    In this paper, laboratory tests of recycled aggregate concrete(RAC) were carried out to investigate the influence of net water-binder ratio, sand percentage substitution recycled fine aggregate for natural sand on compressive strength and flexural strength of RAC. The results indicate that relatively high strength and good fluidity of RAC can be obtained by application of suitable chemical admixture addition of fly ash and silica fume, optimization of sand percentage. The application of recycled fine aggregate (RFA) for pavement construction cannot meet the requirements in specification.
