4/27/2017 · Bitumen is a highly viscous form of petroleum which is widely produced in the oil and gas industry. Large natural deposits of bitumen may be found, for example, in Canadian oil sands. The high viscosity of bitumen is at least partly due to the asphaltenes content of bitumen, which can complicate the recovery and transportation of bitumen.
the plant is working, the so-called plant utilization. The greater the plant utilization, the more (preventative) maintenance is required. When companies wrongly perceive these to be a cost, not an investment…they are in trouble. This is like waiting for your car to break down rather than having it regularly serviced

Use fluid bituminous binder, mix it with aggregate at normal temperature. Mixing may be done at a plant (plant mix) or on the prepared roadway base (road mix).
Jan 11, 2016 · Bitumen Emulsion – what, why & how. Bitumen emulsion is a mixture of water & bitumen. Hey wait, we know that bitumen is a oil product and it cannot be mixed with water. That is why we add an emulsifier (a surface active agent) with water before adding bitumen.
bitumen at the mixing plant has been overheated, it may be worth while to check the penetration as excessive heating hardens the bitumen. One particular use of this method of sampling is that if some adjustment is required to the bitumen content, a number of samples may be made at various bitumen contents to determine which is the most ...
