针对港区道路的重载交通特性，进行橡胶沥青混合料室内单轴压缩试验、车辙试验及小梁弯曲试验。结果表明：橡胶沥青混合料的回弹模量、高温性能与 SBS 改性沥青混合料相当，但其疲劳性能最好，比基质沥青混合料高1倍多。将橡胶沥青混合料用于试验路段，结果表明：橡胶沥青路面的路表渗水系数、混合料压实度、构造深度以及表面抗滑系数都能够满足规范基本要求。基于试验，提出港区道路适用的路面结构形式为4 cm 橡胶沥青 AC －13＋6 cm 基质沥青 AC －20。

In allusion to heavy load traffic feature of port roads,this paper carries out indoor uniaxial compression test,wheel rutting test and bending test of small beams for rubber asphalt mixture.The results show that the elastic modulus and high -temperature property of rubber asphalt mixture are equivalent to SBS modified asphalt mixture,but fatigue performance is the best and above 1 time higher than matrix asphalt mixture.The paper applies rubber asphalt mixture to test sections,and the results show that the surface water seepage coefficient,compactness of mixture,structure depth and surface resistant coefficient of rubber asphalt pavement can satisfy the basic requirements of the specifications.On the basis of test, the paper proposes pavement structural form 4cm rubber asphalt AC -13 +6cm matrix asphalt AC -20 applicable to port roads.
