Eating Bitumen ?

Another day, another tense showdown between a motorist and a cyclist emerges online.
This time the pair clashed in Reading in the UK and the driver has most certainly come off second best by finishing the dispute face down in a gutter courtesy of a ill-considered kick to the rider’s back wheel.

The face off begins when the unknown cyclist gets annoyed at what he sees as a dangerously close pass by the motorist. As any helmet-cam wearing rider would do in this day and age, he pursues the driver to express his views on the situation.
Words are exchanged.
Talks break down. Photo: YouTube
Words like: “Are you a f---ing tank?” and “Do you need to drive in the road?” and “Get a car”.
The pair go on to discuss the pros and cons of helmets, seat belts and the nuances of local road rules. The driver runs out of patience and decides to seize the camera in evidence, we presume, once the cyclist signals his plans to call the police.

A short chase, a swift kick and a painful looking fall later, we have all the makings of yet another viral car versus bike video.
Uploaded last Thursday, more than 1.5 million people have now watched the footage.
Now, we're not saying Australians are perfect. We've had our share of tension between two wheeled and four-wheeled road users too, but tempers in Britain seem to fray a lot on this issue. Maybe it's something to do with the presence of helmet cams though?
Or perhaps it's just that Aussies take a "less talk, more action approach" as this scary video of a car clipping a cyclist shows. The angry man in the previous video, it turns out, was an Aussie ex-pat as well.
Neither locality nor nationality have anything to do with it though. Where ever humans operate vehicles, disputes are bound to happen, as are accidents. Both cyclists and motorists are more than capable of being at fault as well.
And there will always be someone prepared to take matters into their own hands.

Another Bitumen Spill

The product tanker Sunpower overflowed cargo tank with bitumen, which spilled in the Huelva Port, Spain. The spilled quantity is around 20 tonnes and caused water pollution in the Spanish port. 
The local authorities detained the ship and started investigation of the accident. It was estimated that crew had failed to maintain the required procedures during cargo operations, which led to the spill. 
The further investigation is on way and ship operator should pay the clean-up and other associated costs, as well as the fine for the water pollution. 
The port immediately started emergency anti-pollution measures, surrounding the leaking product tanker Sunpower with oil booms to contain the spill. The vessel will be released after the shipowner deposit the due money and fines for water pollution.
The product tanker Sunpower (IMO: 9521643) is owned and operated by the Greek company Queensway Navigation. The ship has overall length of 102.00 m, moulded beam of 16.00 m and maximum draft of 4.50 m. The deadweight of the vessel is 4,999 DWT and the gross tonnage is 3,691 GRT. 
Sunpower was built in 2008 by Zhejiang Tenglong Shipyard in Wenling, China and classified by China Classification Society.

Cement to replace Bitumen ? May be Cheaper



Besieged with low capacity utilisation, cement manufacturers are prodding governments to use cement for making roads instead of the bitumen to spur demand for cement. The Cement Manufacturers Association is harping on the savings that will accrue due to the use of concrete due to the near zero maintenance costs and longer life of the roads.

Manufacturers are ready to provide cement at lower prices for bulk purchases by the road contractors. The price could vary from Rs 250 to 260 a bag compared to Rs 320-350 sold in the retail market, according to M Ravinder Reddy, director (marketing), head of marketing-Vicat India.

Typically, initial costs for a cement road are about 20 per cent higher compared to bitumen roads. In case of the concrete roads, it costs about Rs 1,400 to 1,500 per sq m and Rs 1,100 to 1,200 for bitumen roads. According to Indian Road Congress, a bitumen road has to be topped at least once every five years, implying that the road needs to be re-laid four times in a period of 20 years. However, the frequency in actual situations is higher. In the case of concrete roads, there is no maintenance and they could last for 25 to 30 years, said Ramachandra, technical head (south), Ultratech.

He said white top roads were built for about 150 km in Chennai and in Mumbai. “Typically, cement gets its strength after curing for 28 days. But by using a high grade cement, curing time could be reduced to seven days without affecting the strength,” he said.

Also, most of the bitumen, which is a petroleum byproduct, is imported and costs Rs 38,000 a tonne.

It requires about 800 to 1,000 tons cement for laying one-km-long, two-way road that is 7 m wide. “We are hoping that about 100 km are awarded. This will mean an enhanced capacity utilisation of five to eight per cent,” said Ramachandra, adding that road projects would be executed by contractors and not by cement makers, whose role should be limited to providing technical assistance. It had begun a demo project of one km in Hyderabad.

The total manufacturing capacity in South India is about 150 mt with capacity utilisation ranging from 55 to 60 per cent. Though the sector has seen slow growth, cement players were hopeful of the demand increasing on the back of government housing programmes, irrigation projects, roads and infrastructure projects, said Reddy.

Processed Bitumen Attracts Better Price

Indonesia’s biggest construction company, state-owned Wijaya Karya (WIKA), expects to expand its market to China by selling value-added asphalt that it will soon develop. 

WIKA corporate secretary Suradi said that the company’s asphalt unit, Buton-based WIKA Bitumen, was assessing a plan to develop granular asphalt — extracted asphalt in the form of particles — for which overseas demand, particularly in China, was high. 

In addition, the properly processed asphalt product was marketed at a higher price than raw asphalt, which the company currently focused on, and was easier to pack, enabling shipment at a low cost. 

“The Chinese market has very good potential for exports. However, pricing will still be our biggest challenge as plunging commodity prices have not allowed us to find favorable prices during the discussions with our potential buyers,” Suradi told The Jakarta Post over the phone.

“This is a determining factor on whether or not WIKA Bitumen will continue with the plan,” he added. 

Suradi further emphasized that mass production would only be guaranteed if the product was well absorbed and well received with suitable pricing.

WIKA Bitumen plans to send samples to the East Asian country in a few weeks after trial production with a small amount of the new asphalt product.

To support the development of granular asphalt, WIKA recently injected Rp 10 billion (US$742,804) to WIKA Bitumen, adding to Rp 150 billion it has provided as working capital in the past few weeks. 

WIKA Bitumen made Rp 60.83 billion in revenue in 2014, down 45 percent from the previous year, and Rp 16.98 billion in net profits in 2014, down 36 percent. 

The firm’s expansion into the granular asphalt business will be important as it aims to more than double its revenue this year to Rp 150 billion from last year and its profit by around 40 percent to Rp 35 
billion, Suradi earlier said as quoted by Kontan. The target could be realized if the macro-economic situation improved along with the contribution of its new product. 

WIKA’s venture into the asphalt business began in late 2013 after the company acquired the whole stake of fellow state-owned firm Sarana Karya for Rp 50 billion, a move that helped it become a fully-integrated construction firm. It then changed the name of the acquired company into WIKA Bitumen.

WIKA proceeded to build an asphalt extracting plant following the acquisition. The facility is slated to operate at full capacity this year with annual output of 50,000 tons.

The company was previously reported to have planned a joint venture with a Chinese firm to develop an asphalt mine, which would be WIKA Bitumen’s third mine.

Suradi, however, said that the plan had yet to be realized as the company was awaiting better economic conditions.

New Bitumen Road @ Coimbatore

The new bitumen road, laid at the bunds of Periyakulam lake at Ukkadam in the Coimbatore City will be ready for two-wheeler users within a couple of days. The civic body with the help of city police has also decided to install a CCTV camera to monitor the place.
However the two-wheeler users will not able to use the newly laid 1.6-kilometre stretch of bitumen road starting from Karumbukkadai to Ukkadam in the early hours of morning. “The two-wheeler users cannot use the stretch between 5 am and 8 am as the lane will be allotted for morning walkers,” said K Vijayakarthikeyan, Commissioner of Coimbatore corporation. 
On Sunday, Municipal Administration and Rural Development Minister SpP Velumani and Mayor P Rajkumar along with the city Police Commissioner AK Viswanathan inspected the spot. The bitumen road has been laid at the bunds of Periyakulam to decongest the traffic at Ukkadam.
Though the civic body laid the bitumen road after removing the paver blocks at the bunds of Periyakulam soon after the two wheeler users complained that they were unable to travel on the road as the path had turned slippery, the civic body has not invested any money on the bitumen road work. “The entire cost for the project will be incurred by the contractor and  corporation money will not be spent on it.
The paver blocks dismantled from bunds of Periyakulam at Ukkadam will be used in Perur lake where we are planning to develop bunds,” said Commissioner Vijayakarthikeyan. “We are also planning to setup a CCTV camera near the lane, which will help us monitor the situation round-the-clock and prevent untoward incidents and anti social elements,” the commissioner added further.  
According to sources, the area near the bunds at Periyakulam was used by people to park tourist vans where anti-social elements allegedly gathered.

Bitumen Emulsion - The Two Things that don't mix

Following the news that a Nexen pipeline has spilled roughly 5,000 cubic metres of emulsion, you might be wondering what emulsion is exactly.
We see emulsion in our everyday lives. Do you eat ice cream? Butter? Mayonnaise? All of those things are examples of emulsion.
To understand what emulsion is, just think of oil and water: two substances that don’t mix.
Using something called an emulsifier, you can change those properties so that the two interact better.
In the case of bitumen, in order to extract the oil out of the ground an emulsifier is used, allowing the thick molasses-like substance to flow.
Thursday’s oil spill contained about 5,000 cubic metres of bitumen emulsion over a 16,000 square-metre area. Clearly a concern to the environment, Nexen said that they are taking measures to ensure that the spillage is contained. Of the amount spilled, about 33 per cent was bitumen. The rest was condensed steam and some sand.
WATCH: Concerns over long-term ecological impacts of Nexen oil spill

Ron Bailey, Nexen’s senior vice president of Canadian operations, told reporters, “We’re also taking mitigation steps as it relates to environment and wildlife, and we are setting up protective equipment…We are deeply concerned about this. We sincerely apologize for the impact that this has caused.”

Orpic, Pörner sign deal for bitumen unit

Oman Oil Refineries and Petroleum Industries Company (Orpic) has signed a deal with Austria-based Pörner Group, a leading engineering contractor, to provide proprietary Biturox technology for a bitumen production unit planned in Sohar, according to a report.


The bitumen production unit will be a part of the multi-billion dollar Sohar Refinery Improvement Project (SRIP) and will enable Oman to produce bitumen in the sultanate for the first time, said the Oman Daily Observer.

The country has completely depended on imports from Iran and the UAE for its bitumen requirements in order to carry out projects such as asphalting of roads, and various other infrastructure related works.

Pörner Group said it will support the construction of a bitumen unit featuring a pair of reactors each with a capacity to produce 516 tonnes per day (tpd) of bitumen, it further reported.

In addition to supplying the licence and basic engineering, the group will also undertake the detailed engineering, pilot testing and commissioning of the new Biturox unit.

Additional assistance will be rendered in the form of start-up support, documentation and training, it said.
