The interactions among large air voids, the dynamic hydraulic pressure, the non-uniformly distributed load, the overload, the environment condition and the material lead to the deficiency of the adhesion between asphalt and aggregate. The immigration of the asphalt leads to the new bleeding and inside raveling. The pumping and settlement occurred once the water penetrates the whole asphalt layer.

大空隙率、动水压力、荷载的非均布、超载以及气候条件与路面材料的相互作用造成了沥青与集料粘附性的相对不足，面层内部沥青膜剥落后向上部迁移，这是新泛油、内部松散的产生机理；更为严重的情况下，外界水直接贯穿沥青面层对基层顶面的冲刷将诱发泛浆和沉陷。
