摘要
针对现有高等级公路半刚性基层水泥稳定碎石易出现收缩裂缝的现象,将聚丙烯纤维掺入水泥稳定碎石混合料,阻止和减少裂缝的发生。对其作用机理和路用性能以及路用性能随龄期的变化规律作了介绍。
Aiming at the phenomena of present highquality highway built in semirigid base course with cement stabilized macadam that is easily contracted and cracked, tried mixing polypropylene fibre with cement stabilized macadamix which can prevent cracks or at least reduce them. Introduces the acting mechanism, property of roadmix pavement and the varying laws of property of this kind of road with the growth of service life.
