Key Technologies Based On The Layer Division Of The Durability Of Highway Asphalt Pavement Structure Design

Based on the current structural design of asphalt pavement in the durability of asphalt at homeand abroad there are certain problems, this paper is to expand research on the durability of asphaltpavement design.First proposed a long-life asphalt pavement design standards, design principles, design ofindicators, as well as at home and abroad durability of asphalt pavement structure based ondivision of the durability of asphalt pavement layer structural design, and proposed a typicalstructure force analysis, the changes in the critical layer thickness and modulus, obtained the bestvalue of the layer, at the same time to study the impact of these two variables on a different road;and then from the long-life asphalt pavement material selection; the durability of semi-rigid asphaltpavement with the ordinary semi-rigid asphalt pavement, full life-cycle analysis of the economic,confirmed the economic feasibility of the construction division of the durability of asphaltpavement layer.
