Coastal Road Phase 1

The Maharashtra Coastal Zone Management Authority (MCZMA) is yet to give its final nod for the Rs 12,000-crore coastal road project, but the BMC is gearing up to begin work on it and will be rolling out the work tenders for the first phase in three months. The decision to roll out the work tenders was taken after the peer review report on the first phase.

“The peer review report for phase 1 of the coastal road project is complete and the tenders for the first phase stretching from Priyadarshini Park to Bandra will be out in three months,” said Additional Municipal Commissioner Sanjay Mukherjee. Apart from Coastal Regulation Zone (CRZ) clearances, the civic body is also awaiting clearances from the Navy as well as the Coast Guard, before actual construction of the coastal road begins.

The current BMC budget has made an allocation of Rs 1,000 crore for the project.

Bitumen Bleeds at High temp..


Don Openshaw is sick of gravel being thrown onto his driveway as the stones loosen in the increasing temperatures.
ROBERT CHARLES/FAIRFAX NZ
Don Openshaw is sick of gravel being thrown onto his driveway as the stones loosen in the increasing temperatures.

Sick of loose gravel covering his driveway a New Plymouth man has resorted to vacuuming up the nuisance stones. 
Don Openshaw said the problems began when the road in front of his house on Keat Place was re-sealed in May.
"It looked at the time like the council had done a reasonable job," he said. 
"But now stones are coming off the bitumen, they're just not holding in the heat."
Openshaw said the council had swept the road three to four times since re-sealing it but he was still having to sweep his own driveway a number of times a week to remove the excess stones.
"I've even resorted to using a vacuum cleaner," he said.
"With the new rubbish system there are more trucks hurtling round the cul-de-sac and taking off the top layer of gravel."
"There are all types of bitumen and I'm not sure about the quality of the stuff they used here but I think it has to be fit for purpose."
Openshaw said if the road was being torn up in the relatively mild temperatures of spring, it would be a "molten mess" come the hotter summer months.
New Plymouth District Council infrastructure manager David Langford said it was normal for there to be some loose chip once a road had been re-sealed. 
"Keat Place has been monitored by our engineers since the new seal was applied and we are satisfied that the seal is bedding in well and performing as expected," he said. 
Langford said bitumen bleeding in hot weather can also occur on asphalt surfaces. However asphalt was reserved for main roads where a stronger surface was needed to withstand higher levels of traffic. 
"The decision on the treatment option [for a road surface] is based on what the most cost effective solution would be whilst still being appropriate from an engineering point of view," he said.
"In many residential areas there is no actual benefit to be gained by using asphalt that would justify the cost," he said.

Bitumen Market Research Report 2015

Global Bitumen Market (Paving Bitumen, Oxidized Bitumen, Cutback Bitumen, Bitumen Emulsion, Polymer Modified Bitumen and Others) for Roadways, Waterproofing, Adhesives, Insulation and Other Applications -

Industry Analysis, Size, Share, Growth, Trends and Forecast, 2014 - 2020
102 pages   Published Date: 2014-09-09  

Bitumen is primarily used as a binder in road construction along with other applications such as electronics, waterproofing for roofing, and in adhesives due to its resistance to water, insulation properties and high durability.

The properties of bitumen can be altered by adding polymers to it, thereby increasing its application scope. Bitumen is known as “asphalt” or “asphalt cement” in North America.

However, “asphalt” is a term used for a mixture of sand, small stones and other filler materials in the rest of the world. This mixture contains about 5% of bitumen. The mixture is known as “asphalt concrete” or more particularly “blacktop” in North America.

Bitumen is available in a number of grades based upon the standard mentioned by certain tests such as penetration test. Bitumen 80/100, bitumen 60/70 and bitumen 40/50 are the most commonly used bitumen, where the numerical values represent hardness of bitumen.

Softer bitumen represents greater penetration units.

Similarly, VG-10, VG-20, VG-30 and VG-40 are the viscosity grades of bitumen. Thus, different grades of bitumen are often represented as bitumen 80/100/VG-10.

Infrastructure activities to improve road networks in developed and developing nations are expected to drive the growth of the bitumen market. Furthermore, increasing applications of polymer modified bitumen (PMB) as chemical additives and adhesives in household and road construction are anticipated to boost the demand for bitumen. Additionally, rising construction activities for industries, commercial buildings and housing are estimated to drive the demand for bitumen over the next six years. However, environmental issues associated with the extraction of bitumen from oil sands are projected to hamper market growth. Increasing substitution of bitumen by concrete is also likely to adversely affect the bitumen market. However, development of bio-based bitumen or bio-bitumen and its commercialization over the next few years is expected to offer opportunities for the bitumen market. Furthermore, development of bio-bitumen is anticipated to ease the production pressure on the depleting fossil fuel reserves.

Paving grade bitumen, which is used in roadway application as a binder for asphalt, was the largest consumed type of bitumen in 2013. It accounted for over 65% of the market share in 2013.

Polymer modified bitumen (PMB) is expected to be the fastest growing segment of the market due to its increasing demand in road construction and roofing applications. Polymer modified bitumen is increasingly used in construction of roadways and waterproofing applications as it offers various advantages such as heating at lower temperatures, ability to increase porosity of roads and enhancement of performance of the applications.

With over 80% share in 2013, road construction was the largest application segment for bitumen due to its high viscosity and stickiness.

Other applications of bitumen include its usage in roofing industry, paints and enamels, adhesives, automotives and decorative applications, and as an insulator in electrical and electronics industry.

Focus of national governments of China and India on improving road network and the consequent inclusion of the same in the five-year plans is anticipated to fuel growth of bitumen in Asia Pacific over the next six years.

However, waterproofing is expected to be the fastest growing application of bitumen during the forecast period, due to growth in infrastructure activities in developing countries such as China and India.

North America was the largest consumer of bitumen in 2013 due to the significant network of roads in the U.S. The region accounted for over 30% of the market in 2013.

Redevelopment and repair of existent roads accounts for the primary consumption of bitumen in this region. This is in contrast to emerging economies where the consumption is driven by development of new infrastructure.

However, Asia Pacific (including China) is expected to be the fastest growing market for bitumen during the forecast period due to rapid industrialization in the region. This is expected to drive infrastructure development in the next few years.

The bitumen market is highly fragmented, with the top eight companies accounting for approximately 39% of the total market share in 2013. Leading bitumen manufacturing companies include Shell Bitumen, NuStar Energy, ExxonMobil, Marathon Oil Company and Valero Energy Corporation.

Looking for Bitumen Tanker Vessels.. Grab One Here

NewLead Holdings Ltd. (OTC: NEWL) ("NewLead" or the "Company") announced today a review of the commercial performance of one of its bitumen tanker vessels, the MT Nepheli ("Nepheli") since the vessel was delivered to NewLead's fleet.
The Nepheli is a 2009-built bitumen tanker vessel of 3,416 dwt and is one of the five bitumen tanker vessels that were delivered to NewLead's fleet in the fourth quarter of 2014.
When NewLead took delivery of the Nepheli in November 2014, the vessel was already chartered-out on a time charter agreement for one year at a net rate of US $6,700 per day. The time charter contract was concluded at the end of July 2015 and from delivery of the vessel to NewLead until such time, 82,473.76 tons of asphalt were transported. Following the conclusion in July 2015, NewLead entered into a new time charter contract, in direct continuation of the prior contract, for a one year period at a gross rate of US $7,400per day less 3.75% commission payable to third parties. The Nepheli will be principally trading in the Middle East area.
Upon delivery of the Nepheli to NewLead in November 2014, the Company invested in the maintenance, improvement and upgrade of the vessel's condition. The vessel's improved technical condition allowed for an increase of approximately 5% in the vessel's cargo in-take capacity and a decrease in the fuel consumption for steaming and cargo heating, as well as an improvement of the speed and consumption of the vessel.
Mr. Michael Zolotas, Chairman and Chief Executive Officer of NewLead, stated, "NewLead's investment in the improvement of the condition of the Nepheli enhanced the commercial performance and tradability of the vessel. Together with the oil major vettings, the Nepheli has been attracting reputable charterers' attention. Our decision to invest in the technical improvement of the vessel upon her delivery to NewLead is expected to enhance the cash flow of NewLead."
Mr. Zolotas added, "The enhanced performance of the Nepheli in the time charter contract upon the delivery of the vessel to NewLead resulted in the renewal of the charter party agreement with improved terms. We will continue to capitalize on the commercial and technical expertise of NewLead which are fundamental in the bitumen market while aiming to expand the Company's fleet with modern bitumen vessels. "
NewLead has approximately 50% and 74.75% of its operating days covered for 2015 and 20% and 16.27% of its operating days covered for 2016 for its dry bulk and tanker vessels, respectively.

Recycled Toners Put to Good and Final Use - Guess What .. Replacing Bitumen

Asphalt is Getting New Life from Recycled Printer Ink

Did you know that the ink in your printer is considered one of the most expensive liquids in the world? If you were to fill up your standard 15 gallon gas tank with printer ink, it would cost you almost $75,000. Ouch.
Once your printer runs out of ink, consumers (hopefully) recycle the cartridges, which leaves millions of them forgotten in landfills. Inside those cartridges, it’s estimated that there is still 13% of unused ink just sitting there goring to waste.
Enter the asphalt industry, king of recycling, to make good use of those old cartridges. This time, it's an Australian company, Downer Group, who has been working to re-purpose this leftover toner powder for use in asphalt mixes.

How it Works

The material inside your toner cartridges is actually a small plastic powder material that is melted down when printed on to paper. When the waste toner is recycled, its low melting point makes it an effective glue in asphalt. This can reduce the use of oil-based bitumen.
TonerPave is the result and it's made by adding MTP (Modified Toner Polymer) to standard asphalt. The toner is blended with recycled oil and is 40% more energy efficient than the manufacturing of standard bitumen, with a relative saving of 270kg of CO2 emissions per ton.
Every ton of the toner-based product used in the asphalt mix replaces 600kg of bitumen and 400kg of fine aggregates, such as sand and soil. Almost 100 toner cartridges are needed to make 1 ton of asphalt.

TonerPave Put to the Test

“We have these toner cartridges and the challenge is to do something with them,” says Peter Tamblyn, marketing manager at Close the Loop. “This is the only commercially viable waste toner solution on the planet, it’s a good thing.”
Currently, the product, called TonerPave is being extracted from cartridges in Melbourne and then transferred to Sydney where it’s being blended and placed as tests on roadways.
The City of Sydney’s construction services manager, Andrew Christie, said the product must prove as resilient as regular asphalt and have the same 30-year lifespan. “In two or three years we should have an indication if it is a good alternative to traditional asphalt. Hopefully we can start to use it across Australia,” he said.
At $150 per ton, the mix costs the same as standard asphalt, but Christie expects this to drop as the product matures. Raw materials represent a small portion of road resurfacing costs, he said, which is mainly taken up by machinery and staffing.
However, this is the first time TonerPave has been combined with warm mix asphalt, which has been in use in Sydney since 2010. Warm mix asphalt is heated at temperatures lower than regular asphalt and saves the city 24,000kg of CO2 emissions each year.
Christie says 30% of this new mix is also comprised of recycled asphalt, significantly higher than the industry requirement of at least 10%.
The measure is part of the City of Sydney’s target to reduce its greenhouse gas emissions by 70% by 2030. It was the first local council in Australia to be certified carbon neutral under the National Carbon Offset Standard.
All of Australia’s waste toner powder could theoretically one day be used in asphalt mix, Tamblyn said, but many people throw their toner out rather than recycle it.
“If we could get our hands on all of Australia’s waste toner we would happily use it,” he said.
Tamblyn says “the rest of the world is looking at this” as the company begins investigating importing toner waste from overseas markets.

Kazakhastan Builds Bitumen Plant


1/3
   KAZINFORM In a month, i.e. November 20, there is planned the output of the first trial batch of bitumen at the plant named «Caspi Bitum», that has been stated at the workshop on implementation of the investment project called  "Production of bitumen road ", which was being conducted at the plant.

"Construction of the plant is complete, there is active phase of commissioning. As for power supply all works have been finished. The first batch of oil is to be October 25 and October 30 there will be the second supply.

 Running-in of oil product processing equipment will be carried out on October 26. Prior to October 28 the working committee will finalize its activity, and the state acceptance of the plant is to be take place November 7 this year", said the chairman of the Board of Kazakhstan Petrochemical Industries JSC (KPI) Dauletkeri Ergaliev.

Despite these optimistic forecasts, the participants voiced a number of problems and their solutions.

"In February, I was reported on the fact that in April the plant would be launched. Closer to the summer I was again reported on the readiness by September. It is worth remembering that the project is a part of the Republican map of industrialization, it is planned to produce bitumen that is required for development of the manufacturing industry. It will be produced in solid form and not in liquid. There is not yet a plant producing this sort of bitumen on the territory of the CIS", said the mayor of Mangystau region Alik Aidarbayev.

The total cost of the project is subject to payment of interest, since it runs on borrowed funds - 290 million U.S. dollars. The client is «Caspi Bitum» JV, project participants are  « KPI » JSC and "CITIC Kazakhstan", and funding is provided from two sources: 80 % -  "BANK of CHIN" borrowings, and 20 % are the means of the project parties.

Canada's Fuel Cost to Raise with the Pipelines ?

Comments made by the late Peter Lougheed hung over public hearings Monday about a pipeline that would ship bitumen from Alberta's oilsands to Asian markets.Both sides in the debate tried to claim the support of the former Alberta premier who died Sept. 13.

Rick Neufeld, lawyer for pipeline proponent Enbridge (TSX:ENB), suggested Lougheed backed the line's construction."In one of his last interviews, didn't he say the (Northern Gateway) pipeline was essential for Alberta?" he asked while cross-examining Gil McGowan, president of the Alberta Federation of Labour.
In response, McGowan suggested Lougheed was sympathetic to the federation's concerns that too many oilsands projects were exporting raw bitumen and robbing Albertans of some of the benefits they would reap from upgrading it in the province.

"Lougheed took an activist approach to ensure we had a value-added industry," McGowan told the National Energy Board. "It wouldn't have been here without government policy and intervention."

The federation's previous testimony that the $6-billion project would make it harder to create upgrading and refining jobs in Alberta, as well as increase fuel prices throughout Canada, came under repeated attack in Monday's cross-examination.

Neufeld pointed out there is no shortage of bitumen currently available for anyone interesting in building a refinery. Nor has Calgary-based Enbridge ever said it would restrict access to bitumen.

He disputed the notion that pipelines encourage the export of raw natural resources. He noted that the Transmountain pipeline originally built to transport crude now moves both oil and refined products.
McGowan responded that the labour group believes projects such as Northern Gateway help price Alberta out of the market for new industrial development. He said the pipeline would only help speed oilsands development, creating demands for labour and materials that drive up their cost.

Neufeld also grilled federation adviser Robyn Allan over her testimony that the 550,000-barrel-a-day pipeline would drive up fuel costs in the rest of Canada.

"So if Canadian producers get higher netbacks in Edmonton, refineries will have to pay more in New Brunswick?" he asked.

Allan responded that oil shipped to Asia would no longer be available to North Americans, which will eventually raise its price.

"When you take oil out of North America and take it to Asia the price increase is going to affect all markets in the long run," she said.

Enbridge analysts have argued that the price of oil is set globally and the Gateway pipeline wouldn't change the price of the Venezuelan, European and Middle Eastern oil on which refineries in Central Canada rely.
In afternoon testimony, federation lawyer Leanne Chahley revisited potential Chinese ownership shares in the pipeline.

Cross-examining a panel of energy producers who hope to ship on Gateway, Chahley pointed out that one of them — Nexen — is being bought out by the Chinese National Offshore Oil Corp. Nexen holds one of 10 shares that give it an option for a five per cent ownership stake.

MEG Energy — owner of another of the ownership options — is about 15 per cent owned by the Chinese corporation.

Chahley also pointed out that Total E and P Canada, another hopeful Gateway shipper, is involved with two developments that include some level of Chinese investment.

Zambia Reopens Bitumen Plant

THE government says the reopening of the bitumen production plant at Indeni Refinery in Ndola will help reduce the cost of road construction in the country.

Indeni used to produce bitumen as a by-product of crude oil processing but the plant was closed down after the machinery and equipment became obsolete.

In an interview yesterday, energy permanent secretary George Zulu said the government was spending US$20 million to refurbish the plant whose commissioning is set for this October.

"It will have a capacity of 400 tonnes per day and this will be sufficient for local requirements and we shall be able to export some quantities. We are happy because the reopening of the plant will help reduce the cost of road construction since bitumen is a major component," said Zulu.

"The bitumen plant will have drum filling facilities and now the residue of crude oil will be put to good use as compared to the current situation where everything is lost after refining crude oil."

Last week, Sable Transport and Contractors managing director Iqbal Alloo observed that non-availability of bitumen and heavy rainfall in some parts of the country affected progress on most road works being undertaken by the company.

Noise Supressing Rubberized Asphalt

Noise-suppressing rubberized asphalt to be used - Bitumen EngineeringAbstract:
City of Canyon Lake, California, USA decided to apply rubberized asphalt layer on existing road surfaces to reduce traffic noise, improve durability and increase lifetime of pavements.

Article:
When the Railroad Canyon Rd. (in City of Canyon Lake, California, USA) improvement project is completed in eight months, the main drag through Canyon Lake will be wider, better looking and quieter.

The $9 million construction project will expand RRC Rd. in Canyon Lake from four lanes to six, result in new monument signs at the City’s entrance as well as retaining walls, drought-tolerant landscaping and decorative features.

“Although there seems to be more noise coming from Railroad Canyon Rd. after the trees and shrubs were removed, the final product will be much quieter and smoother,” says Mayor Jordan Ehrenkranz.

The retaining wall will be rebuilt, new landscaping will be added and the road will be made of noise-suppressing rubberized asphalt.

The road surface will consist of regular asphalt that is mixed with crumb rubber made from ground-up used tires. Not only does the road material recycle discarded tires that might otherwise end up in a landfill, but the rubberized asphalt road lasts longer than a conventional road and can dramatically reduce road noise.

The Arizona Department of Transportation discovered that asphalt rubber overlays on roads resulted in up to a 12-decibel reduction in road noise, with a typical reduction of seven to nine decibels.

A three-decibel reduction in road noise has the same effect as doubling the distance between the source of the noise and the person hearing it. Or put another way, reducing traffic noise by 50 percent.

The overlay is an economical alternative to sound walls, which are expensive to build and may cause the noise to reflect or “bounce” to a wider area.

Rubberized asphalt roads also last longer. Roads paved with conventional asphalt require some sort of maintenance every few years. Because of the resistance to cracking and aging exhibited by rubber-modified asphalt, roads paved with rubber-modified asphalt applications generally experience longer service lives before maintenance is required.

Longevity is not the only benefit. Each year, more than 60 million tires end up in stockpiles and landfills. Depending upon the application, between 500 and 2,000 scrap tires can be recycled in each lane mile of rubberized asphalt pavement. That means for a one-mile section of a six-lane highway, anywhere between 3,000 and 12,000 tires can be used in creating a safer, quieter, longer-lasting road!
During all the work on RRC Rd., the City and the contractor ask drivers to keep their cars out of the work zone, watch out for truck crossings, pay attention to flag people and obey the 35 mph speed limit in the construction zone. Violators face double fines.
