Experimental study on the tensile performance of cement stabilized recycled aggregate pavement base

As the main bearing stratum of pavement, the base mixture is equivalently subject to external shear stress when unevenly stressed, so the splitting performance is an important parameter to measure its engineering characteristics. The results of splitting and splitting rebound test showed that the st...

Summary:As the main bearing stratum of pavement, the base mixture is equivalently subject to external shear stress when unevenly stressed, so the splitting performance is an important parameter to measure its engineering characteristics. The results of splitting and splitting rebound test showed that the strength and rebound modulus of cement stabilized macadam and cement stabilized recycled aggregate increased exponentially with age. Through comparative analysis, it was found that the splitting and tensile properties of cement stabilized recycled aggregate were slightly inferior to that of cement stabilized macadam. Finally, the strength calculation formula of the mixture was derived, which could provide reference for practical engineering.
