摘要:
应用BISAR软件计算了不同层间接触条件下的沥青面层剪应力,通过直剪试验测定了洒布不同粘层材料的复合马歇尔试件的抗剪强度,并采用车辙试验测定复合式车辙板的Ds和总变形量.研究结果表明:完全光滑的层间接触条件大幅提高了沥青面层的最大剪应力,加速沥青面层发生剪切破坏而出现车辙;粘层提高了层间抗剪强度,不同的粘层材料对层间接触条件的改善效果不同;高抗剪强度的层间接触能提高复合式车辙板的高温性能.
Abstract:
The influence of different interlayer touch types on high—temperature of asphalt pavement was dis—cussed．The influence of different interlayer touch types on shear stress of asphalt pavement was studied withthe soft of BISAR，and the anti—shear strength of compound Marshall sample bonded with different tack coatswas tested with the method of direct shear test．At last，the DS and total deformation of compound rutting sam—pie was tested by the rutting test．The results showed that：the shear stress of asphalt surface increased sub—stantially when the interlayer touch type was smooth，and as aresult，the rutting was easier to oceurred；thetack coat improved the anti—shear strength of interlayer and different materials had different effect；the interlayer touch with high anti—shear strength would help to improve the high—temperature of compound sample；it is meaningful to take appropriate measures to improve the interlayer touch condition for improving high tern—perature performance of asphalt pavement．
