Criteria for Substantiation of Rational Pavement Design as Bases of Traffic Safety throughout Life Cycle of Transport Structures

Presently used conventional Russian pavements including macadam base asphalt covering loses its advantages under the current conditions of heavy and high traffic. In this regard, for the development of the country's economy and transport infrastructure, a rational pavement design is developed, which is presented in rigid fragmented asphalt bedding course. It provides high homogeneity and uniform strength of coating with low variation factors resulting in increase of the pavement life time and service life. The rational pavement design with a fragmented base layer compared to the conventional one has a higher resistance to formation of ruts and cracks that improves safety and reduces the risk of an accident.
