Paper Title:
Experimental Study on Shear Resistance and Water Retention of Graded Gravel Base
  Abstract

Abstract. Through the experimental analysis on performance of the water permeability and conservation and the shear resistance of graded gravel base, the influencing factors and changing rules, as well as the internal relations of the drainage ability and structural performance are found out; the key factor for balancing the contradiction lies in the scope and content of the fine aggregates of graded gravel. Provided that other constraint conditions are met during the gradation design, good water permeability and conservation performance of graded gravel permeable base shall be guaranteed as long as the content of the fine aggregates of graded gravel could be controlled within a reasonable scope, meanwhile, the mechanical stability could also be ensured. The paper provides the method for determining the content scope of fine aggregates of graded gravel, and references for the design of graded gravel permeable base of the porous pavement.
