Cracks in asphalt are a common sight, but a pain to repair. It is expensive and because the roads need to be closed down for construction, traffic jams occur. Researchers at polymer institute of research and development in Iran are working on a solution by creating pothole proof, self-healing asphalt, which can be mended using a magnet field.Bitumen is a sticky, viscous black binder used in road construction, made from petroleum. The bitumen is mixed with aggregate particles for the use of road construction, but slowly crumbles down due to wear and tear, differences in temperature and chemical substances. The cracks that develop are first microscopic, but eventually grow under the weight of traffic.Benefit of Gilsonite in self repair asphaltTo make the self-healing asphalt which is blended by Gilsonite and [...]
The Rice lab of chemist James Tour developed anodes comprising porous carbon made from gilsonite that showed exceptional stability after more than 500 charge-discharge cycles. A high-current density of 20 milliamps per square centimeter demonstrated the material’s promise for use in rapid charge and discharge devices that require high-power density.Above image -Scanning electron microscope images show an anode of gilsonite, graphene nanoribbons and lithium at left and the same material without lithium at right. The material was developed at Rice University and shows promise for high-capacity lithium batteries that charge 20 times faster than commercial lithium-ion batteries. Courtesy of the Tour Group“The capacity of these batteries is enormous, but what is equally remarkable is that we can bring them from zero [...]
Due increase of crude price and then bitumen price Chinese started to buy Gilsonite from Iran again in high volume.Normally they are buying in raw form and pulverizing in very fine particle size to save some cost and control the quality.On September and October compare other months since 2013 till today,Iranian exporter suppiled Gilsonite based on 7000MT lump to Qingdao port packed in 1000Kg jumbo bag.On end of October and Novermber more than 10000MT booked and in high season of Gilsonite China would be the market for Iranian miner.The only problem from now to March is rainly season and stop of business in mine area [...]
