基于中法标准的改性沥青混合料性能评价
Performance Evaluation of Modified Asphalt Mixture Based on Sino-French Standards
摘要
Abstract
In order to compare the evaluation systems of asphalt mixtures performance testing between China and France,the road performance of typical mixtures(AC-13 and BBSG-14)under the two systems were evaluated.The above two types of asphalt mixtures were formed with FLEX 20 modified asphalt.The performance was evaluated by Marshall specimen performance tests,immersion Marshall tests,high-temperature rutting tests,low-temperature bending tests under Chinese standard system,as well as complex modulus tests,rutting deformation rate tests,and Doraemon tests under French standard system.The experimental results show that FLEX 20 modified asphalt mix-ture has good high-temperature performance,low-temperature performance and water stability;The dynamic sta-bility of AC-13 is 6 times that of BBSG-14;The bending strength of AC-13 is only 66％of BBSG-14;In terms of water stability,the difference is relatively small.The Chinese evaluation method is more rigorous.The asphalt mix-ture road performance evaluation methods of Sino-Franch have a certain correlation.The test results are of great sig-nificance for promoting Sino-Franchroad performance evaluation system of asphalt mixtures.关键词
