摘　　要：为更加系统地了解高模量沥青混凝土材料的组成特性,分析了法国高模量沥青混凝土材料组成设计方法,从级配类型、成型方法、沥青用量的确定和验证试验等方面对中国马歇尔设计方法进行调整,并经过了室内马歇尔试验、车辙试验、水损害试验和模量试验的验证。结果表明:调整后的设计方法适用于添加外掺剂的高模量沥青混凝土配合比设计,设计出的高模量沥青混凝土能够满足《公路沥青路面施工技术规范》的技术要求;同时建议将模量试验作为高模量沥青混凝土材料配合比设计时的验证试验。In order to realize composition character of high modulus asphalt concrete （HMAC）, the material composition design method of HMAC in France was analyzed, special adjustments about grade type, molding method, determination of the optimum asphalt content, certification tests of Marshall design method were conducted and were verified with Marshall test, rutting test, moisture damage test and modulus test. Results show that the adjusted method is suitable for mixture ratio design of the HMAC which is produced by adding additives into conventional asphalt mixes, the performance of the high modulus mixtures can meet the requirements of the Specification Technical Standard for Highway Asphalt Pavement Construction of China; it is also proposed that the modulus test should be taken as the certification test for HMAC. 9 tabs, 5 figs, 6 refs.
