Construction of Outer Ring Road /MONICAH MWANGI
Road contractors have abandoned more than 60 projects since 2013 due to nonpayment by the county. The projects are worth Sh1.7 billion.
For years residents have been complaining about the high number of stalled projects and poor services by the county government.
The contractors who quit will lose out because the county will not pay them even for the little work they had done before they withdrew their services. City Hall has already re-advertised the projects.
Acting Transport chief officer Fredrick Karanja says many more infrastructure projects worth billions of shillings have stalled. But contractors have agreed to carry on with the work after the new administration committed to pay them.
“We have been engaging them and we will pay those who have agreed to come back. We have so far paid out Sh300 million,” Karanja said.
This comes as it emerged that at least four people are killed each day on the newly constructed Outer Ring Road in Eastlands.
Abandoned projects include John Osogo and Muigai Kenyatta roads in Dandora. The two, which lead to Dandora dumpsite, were allocated Sh210 million in the 2016-17 financial year. Others include Ole Sagane Road in Madaraka, which was being rehabilitated, construction of a non-motorised transport route in Kibera and rehabilitation of California Road in Eastleigh.
tenders paid
Transport executive Mohammed Dagane said non-payment of contractors is the sector’s main problem. In the current financial year, the executive said, Sh1.2 billion of Sh4.9 billion tenders awarded have been paid.
The two spoke during a breakfast meeting with journalists at the Sarova Stanley Hotel. All the CECs attended the forum.
Dagane also blamed the poor state of roads in the county on inadequate technical personnel, lack of county-owned basic construction equipment, under-investment in public transport and massive encroachment on road reserves.
Meanwhile, the county government has written to the Kenya Urban Roads Authority to construct footbridges and other safety structures to reduce the numbers accidents on the road.
“We have asked them to introduce safe crossing ways like tunnels and underpasses. But another problem is the habit of Kenyan drivers who always want to test their vehicles whenever a new road is built,” Karanja said.

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.
