Study On Optimization And Function For Thin-layer-asphalt Pavement Structure

National road improvement of quantity and quality of benefits, it makes roadconstruction economy increasingly attention, thin layer the resulting. Because of drivingcomfort, asphalt pavement construction speed is quick, convenient maintenance, thin layermainly for asphalt pavement the road.Through the analysis of the different functions of each structural layer of asphaltpavement and characteristics of modified asphalt macadam, waterproofing, drainage ofpavement crack layer composition design, and designed the low temperature tensile test,compression test at low temperature, low temperature resistance to impact test and othertest methods.
