The Study on Road Performance and Pavement Structure Analysis for the Base Layer Material Stabilized by SRX

Abstract:

In order to overcome the weakness of semi-rigidity base layer，the road performance of the SRX(Solution Road RomixSoilfix) stabilized base material and the mechanics response of asphalt pavement with the base layer stabilized by SRX have been studied in this paper. The CBR value and resilient modulus of SRX stabilized base material were given by indoor test. Based on the multiple layer elastic theory, both the mechanical responses of asphalt pavement structure with the SRX stabilized base and semi-rigid base were given, and according to the calculation results, the two kinds of pavement structure fatigue life were analyzed. The results have shown that the CBR value of SRX flexible material is greater than that of graded crushed stone; the SRX stable material can be used as pavement base layer, but the fatigue performance of SRX flexible base materials should be paid much attention.
