摘要
天然沥青高模量混合料的动态模量超过14000 MPa,远大于常规改性沥青混合料的模量。因此,将其应用到国道工程中,可大幅提升承载力,延长路面使用寿命,解决国道车辙问题。基于此,结合108国道工程实际情况,探讨天然沥青高模量混合料的应用思路,以获取更加真实、实用的数据及参考质量,为同类工程施工建设提供参考及借鉴。
The dynamic modulus of natural asphalt high-modulus mixture exceeds 14000 MPa,which is much larger than that of conventional modified asphalt mixture.Therefore,applying it to the national highway project can greatly improve the bearing capacity,extend the service life of the road surface,and solve the problem of rutting on the national highway.Based on this,this article combined with the actual situation of National Highway 108 project,explores the application ideas of natural asphalt high modulus mixture,in order to obtain more realistic and practical data and reference quality,to provide reference and reference for similar projects.
