- 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．
