Abstract:
The start point in this paper is dynamic load damage caused by hydrodynamic pressure to the inside void of cement stabilized macadam base considering the affect of gradation type, testing time and cracking simulation. Then the moisture damage rule of cement stabilized macadam was investigated in the lab by using the hydrodynamic pressure simulation device and testing system. Test results shows that the cement stabilized macadam with dense framework structure has better moisture resistant performance than mixtures with suspend dense structure. And the strength deterioration is just one third of origin one when crack in base is loaded by hydrodynamic pressure.
Key words: cement stabilized gravel base hydrodynamic pressure compressive strength loss rate
