Road infrastructure is a vital system that has a direct influence on economy of states. In this regard, there is a direct relationship between the coating conditions of automobile roads and the countryпїЅs industrial development. This dynamic increases intensity and traffic congestion constantly. Thereby, it is necessary to eliminate the damages and increase the exploitation time of road coatings. This concerns mostly asphalt - concrete pavements which form the basis of automobile road networks in countries. Based...

Thermal recovery methods within catalytic aquathermolysis is a new promising exploitation approach in extracting heavy oil and natural bitumen. In this technology, the catalyst is added in a stage of injecting high-temperature steam. At the pay zone, three types of reactions takes place: thermolysis, reaction of high temperature steam and catalysis. As a result, the injected steam changes to water transferring its heat to rocks across the interface. Thus, the interfaces of catalyst solutions and hot rocks are cruc...

Changes in group chemical composition in the modification processes are not dependent just on physical and chemical characteristics of bitumen, but rather on structural features of raw material composition and its modification products. The investigation of bitumen is difficult due to formation of paraffinic, naphthenic and aromatic group combinations. The result of modification is bitumen transformation, and this phenomenon is observed by quantitative change in structural fragment content. One of the most informa...
