不同空隙率条件下沥青路面抗滑性能对比

沥青路面的抗滑性与车辆的行驶安全息息相关,基于SAC-16和AC-16I两种级配类型的沥青混合料进行室内试验,通过在不同空隙率条件下对室内轮碾成型的车辙试件进行构造深度试验、摩擦系数试验,对沥青路面抗滑性与沥青混合料空隙率的关系及抗滑性影响进行了试验研究,研究表明：随着空隙率的增加,沥青混合料的表面构造深度增加,沥青混凝土表面层摩擦系数、混合料级配和空隙率没有明显的变化.

Pavement Skid Resistance Comparation Based on Different Porosity Conditions

The asphalt pavement skid resistance is closely related to driving safety, based on laboratory test of two gradation types of asphalt mixture of SAC--16 and AC--16I, for structural depth test, through structure depth and friction coefficient test of rutting samples created by interior wheel compaction under different porosity conditions, this paper makes research of the relation between asphalt pavement skid re- sistance and asphalt mixture porosity and of the influence on skid resistance. The research shows that the depth of surface structure of asphalt pavement increases with the increasing porosity, while the friction co- efficient of the surface asphalt concrete layer, the mixture gradation and the porosity have no change.
