摘　　要：为了增加道路工程验收的方便性与科学性,本文结合2017版沥青路面设计规范,通过间接拉伸模量试验、单轴贯入剪切试验和间接拉伸蠕变试验对施工现场芯样进行试验测试,试验结果表明:不同混合料类型的间接拉伸模量和单轴压缩试验之间均存在明显的比例关系,相关性较强,可以采用间接拉伸模量转化后的单轴压缩模量作为与设计参数进行符合度检验的标准;进行高度修正后的试样单轴贯入剪切试验可以对沥青混合料的高温性能进行验收;采用沥青混合料试件的低温性能来评价沥青胶结料的低温性能具有较好的结果,并且对于路面芯样具有较好的适用性,可以用来验收沥青路面的低温抗裂性能。In order to increase the road engineering acceptance conveniently and scientifically,it is combined the 2017 asphalt pavement design code with the core samples of construction site to be tested by indirect tensile modulus test,uniaxial penetration shear test,and indirect tensile creep test.The indirect tensile modulus and uniaxial compression test of different mixture types have obvious proportional relationship,and the correlation is strong.The uniaxial compression modulus transformed from indirect tensile modulus can be used as the standard for compliance test with design parameters.The high temperature performance of asphalt mixture can be checked and accepted by the uniaxial penetration shear test after height correction.It has a good result to evaluate the low-temperature performance of asphalt binder by using the low-temperature performance of asphalt mixture test piece,and it has a good applicability for the core sample of the pavement,which can be used to check and accept the low-temperature crack resistance performance of the asphalt pavement.
