Drainage Performance Analysis of Pavement Structure with Permeable Base Course and Edge Drainage System

Abstract:

In order to analyze the drainage performance of the pavement structure with permeable base course and edge drainage system, based on the theory of unsaturated seepage, the rainfall infiltration into the highway pavement is simulated numerically and the two-dimensional seepage analysis model is set up. The AASHTO evaluation index t50 is employed to evaluate the drainage performance. The results show that, in comparison with the pavement without internal drainage system, water can be drained away more rapidly from pavement structure with the permeable base course and edge drainage system and the volume water content in pavement is reduced effectively.
