摘要
在研究分析和对比GTM与M arshall试验方法和标准的基础上,侧重论述了GTM试验数据与施工应用二者之间的结合问题。GTM试验方法和理论设计表明,加大压实功(垂直压强)可以进一步提高压实密度,降低最佳油石比;在实际应用中,提出了高温碾压、保热压实工艺。
On the basis of research,analysis and comparison of test method and standard of GTM and Marshall,the combination of GTM test data and the application in construction is elaborated particularly.GTM test method and theory design show that the compaction density could be improved further and the best proportion of oil and stone,could be reduced by increasing the compaction function further（vertical pressure）.The technical of high temperature rolling compaction and heat retention compaction are put forward in the aspects of practical application.
