Abstract:
Both the repeated triaxial test(RTT)and the Hamburg wheel tracking test(HWTT)are adopted to evaluate the high temperature performance of the stone mastic asphalt(SMA)and the mastic asphalt(MA). The correlation of the permanent deformations of the MA and the correlation of the deformation developments of the SMA between the two tests are analyzed, respectively. Results show that both the two tests can effectively identify the high temperature performance of mixtures, and the correlation between the final results of the two tests as well as that between the deformation developments of the two tests are excellent with R2>0.9. In order to further prove the correlation, viscoelastic parameters estimated from the RTT results is used to simulate the rutting development in the HWTT slabs by the finite element method(FEM). Results indicate that the correlation between the two tests is significant with errors less than 10%. It is suitable to predict the rutting development with the viscoelastic parameters obtained from the RTT.
采用重复三轴试验和汉堡车辙试验对SMA和MA两种沥青混合料的高温性能进行评价, 并分别分析了这2种试验之间的MA最终变形的相关性及SMA变形发展过程的相关性. 结果显示, 2种试验方法均能够有效区分混合料高温性能的优劣, 且两者的最终变形及变形发展过程均呈现极好的线性相关关系, 相关性系数均大于0.9. 为了更进一步验证相关性, 利用重复三轴试验获得混合料的粘弹性参数, 对车辙试验进行有限元模拟, 结果表明2种试验方法具有显著的相关关系, 误差小于10%. 将采用重复三轴试验获得沥青混合料的粘弹性参数用于预测车辙的发展是合理有效的.
