| Abstract. | Low elasticity of bitumen, insufficient performance and crack resistance temperature range performance limit lifespan of asphalt concrete pavement on a hot summer period and at low temperatures. One of the main ways to increase the service life of asphalt concrete pavements because of the physical nature and the structural features of asphalt concrete is to change the structure and properties of binding materials, polymer modification. By varying the polymer content in polymer-bitumen binders can achieve any desired performance. This situation is fundamentally changes the situation with knitting – that is, it becomes possible to regulate regional requirements astringent and implement them. The important features of technology for preparation of polymer-bitumen binders are: rapid alignment of the polymer to the bitumen, the ability to maintain a mixture of long time stability of the structure over time. Thus a better distribution (homogenization) of polymers in bitumen medium is achieved by using a colloid mill disperser, and other similar devices. In the Republic of Tatarstan, since 2005, with the construction, repair and reconstruction of roads leading travel organizations were applied asphalt mixture on polymer-bitumen binders in different parts of a total length of over 63 km. |
