摘　　要：玻璃纤维掺入到二灰碎石基层中,对其强度和刚度进行试验。结果表明,掺量一定时,玻纤可提高二灰碎石半刚性基层的强度,随着玻纤掺量的增加,其刚度则有所降低。另外,玻璃纤维还可有效改善二灰碎石基层的韧性。In this research the lime-fly-ash bound macadam was joined with glass fibers in lab tests.The study focuses mainly on the strength and the rigidity of the lime-fly-ash bound macadam enhanced by different content of glass fibers.Based on the test,the conclusion was driven that the glass fiber can increase the strength when the content of glass fibers is proper.With the develop-ment of the content of glass fibers,the rigidity is decreased.The glass fiber can strengthen the flexibility of the lime-fly-ash bound macadam.

关 键 词：玻璃纤维 二灰碎石 强度 刚度
