Asphalt Pavement Strength Variation And Conservation Countermeasures

Highway is an imporant fundamental facility of economy construction. The period of highway construction is short, but highway maintenance is a long period work. The target of the highway maintenance is managing and curing highway seriously, keeping highway a good technology condition and providing a safe and comfort traffic facility for vehicles. A field examination about some bituminous pavement stages of PUYANG city artery is done 'by Dynatest 8000 FWD(Falling Weight Deflectometer), With-the examination data, this paper analyzed and evaluate evety stage technology conclusion about bituminous pavement intensity changed theory.-many science justified maintenance methods a-re carried out, which not only elongate highway usage period but also reduce the cost of maintenance.
