摘　　要：对再生料的级配进行测定,通过级配计算出各档料的用量。通过改变碾压混凝土中粗细集料中再生料的含量,对比碾压混凝土抗压模量,劈裂强度和弹性模量,研究碾压混凝土中的再生粗细集料对碾压混凝土的性能影响,最后得出当再生的粗细集料各占碾压混凝土集料的50%时,性能最好。虽部分性能与全天然集料有所差异,但是仍能满足低等级路面的要求。By testing the grading of reworked material,and calculate the consumption of each gear material.By changing the thickness of RCC of reworked material content in the aggregate,compare the roller compacted concrete compressive modulus,cleavage strength and elastic modulus,study of regeneration in the roller compacted concrete thickness effects on the performance of roller compacted concrete aggregate,and finally it is concluded that when the regenerated aggregate RCC of each degree of 50%,the aggregate performance of the best conclusion.Though there are still some difference between part of the performance and the natural aggregate,it still can meet the requirements of low grade pavement.
