High Grade Highway Asphalt Pavement Of High Performance Mix Design And Application Technology Research

Starting the Beijing-Tianjin Expressway Corridor project management at theBeijing Road and Bridge Road, Hing supplies and Road&Bridge Construction Co.,Ltd., Beijing Xin real cooperation with the U.S. Strategic Highway Research Program(SHRP) is the most important research is one of high-performance asphalt concretepavementasphalt concrete pavement on the highway to re-design, from the experienceof the indicators to move closer to the performance on the basis of indicators,expected to achieve the purpose of improving the pavement performance of asphaltsurface is rough and non-slip dense waterproof. High performance of asphaltpavement SHRP as of the research of proprietary name, it contains a asphalt standardsand aggregate standards, aggregate gradation curve of provisions and mixture of thevolume of the three big content design method, and puts forward the control pointsand the concept of exclusion. High performance modification of the asphalt pavementis advanced it developed a set of new experiment device and method, thusfundamentally changing the current test methods and standard pure nature experienceso as to avoid the which has limitations, high performance of asphalt pavement withmodified asphalt mixture of materials and regulating the new system will test methodand the index of the asphalt pavement with way-use performance establish directrelationship, through high temperature track, the low temperature crack control andfatigue crack, and to improve the purpose of pavement performance, formed aBased on the road with properties on the basis of the asphalt, asphalt mixture to thedesign and construction of new system.This paper, by related project, from the high performance of asphalt concretepavement of the cementing material, aggregate, mixture of test methods and standards,mixture design and performance test and construction mix design and mechanicalequipped with construction aspects to the broad masses of the highway technicalpersonnel in encountered in the construction of the basic problems of technologyprovides some references, and find out the highway pavement in China for a set ofstandards and methods, and promote the high performance of asphalt concretepavement in China in the application of, enhance China’s new technology, newtechnology, new material and new equipment, the popularization and application ofthe level.
