摘　　要：将玻璃纤维掺入水泥稳定碎石中,采用正交试验方法对其进行抗拉强度试验。结果表明,玻璃纤维在早期对水泥稳定碎石的抗拉性能增强作用较大,随着龄期的增加其增强作用逐渐减弱。In this research, the cement stabilized crushed base material was joined with glass fibers in lab tests. The study focuses mainly on the strength of cement stabilized crushed base material with orthogonal experimental design. Based on the tests, the conclusion was drawn that the glass fiber can notably increase the tension strength at early stage. With the increase of the age, the enhancement of tension strength is decreased. The glass fiber can strengthen the flexibility of the lime-fly-ash bound macadam.
