摘　　要：随着城市交通建设的快速发展和公路通行量的不断增加,路面反射裂缝问题日益严重,因此在公路建设时铺设防裂基布显得尤为重要。聚丙烯长丝针刺土工布因其良好的力学性能,已被广泛应用于公路建设中。以G314线阿克苏过境段公路建设工程为例,介绍了聚丙烯长丝针刺土工布在公路工程中的具体施工过程,并对比了实际应用前后的路面状况。结果表明,使用聚丙烯长丝针刺土工布作为防裂材料可以显著延长路面使用寿命,具有明显的经济和社会效益。With the rapid development of urban traffic construction and the continuous increase of highway traffic,the problem of pavement reflection cracks has become increasingly serious,so it is particularly important to lay anti-crack base cloth during highway construction.Polypropylene filament needle-punched geotextile has been widely used in highway construction because of its good mechanical properties.Taking the highway construction project of Aksu transit section of line G314 as an example,the specific construction process of polypropylene filament needle-punched geotextile in highway engineering was introduce and the pavement conditions before and after practical application were compared.The results show that the use of polypropylene filament needle-punched geotextile as anti-crack material can increase the service life of the pavement,which has obvious economic and social benefits,and can provide a reference for highway construction projects.
