The Affect And Research Of Heavy Traffic For Port Road Pavement Structure

The topic for the Binhai New Area "overloading, soft ground, salinization" feature,topics in theoretical studies and traffic surveys, based on the set Port in heavy traffic axleload conversion method, flexible base pavement structure, the structure and combinationsystematically studied, under normal traffic conditions typical asphalt pavement structure,beyond the regulatory requirements of the typical structure of heavy traffic asphaltpavement, the subject of the main conclusions are as follows:1、The truck was set in the axis a representative of port traffic models. Set Port inheavy traffic axle load level, tire pressure standards, axle load times are beyond the scopecovered by existing norms, from the road design and traffic management measures to dealwith heavy traffic. Single wheel group raised more than130KN axle load standard as aheavy axle load limits, the axis load conversion accuracy and determine whether toconsider the impact of heavy convenience.2、Recommended the Binhai New Area, a typical asphalt pavement structure, andreload the typical asphalt pavement structure.3、Uunder heavy load conditions and measures for roadbed reinforcement in the form...
