对掺减缩剂水泥稳定碎石进行了抗压强度试验、劈裂强度试验和干缩试验.结果表明,减缩剂具有减水效应,掺减缩剂水泥稳定碎石90 d抗压强度和劈裂强度增加,但90 d劈裂应变减小,不利于抗裂性能的提高;掺减缩剂水泥稳定碎石干缩应变大幅减小;水泥稳定碎石掺减缩剂的最佳掺量为2%.

The tests of compressive strength, splitting strength and dry shrinkage were made for cement-stabilized macadam with shrinkage reducing agent. Results indicated that shrinkage reducing agent can reduce the optimum water content. With shrinkage reducing agent, the compressive strength and splitting strength at the age of 90 d increases, but the splitting swain decreases. Shrinkage reducing agent can reduce dry shrinkage of cement-stabilized macadam greatly. The optimum dose of shrinkage reducing agent is 2 percent.
