摘要
针对目前我国普通国省干线公路平交道口车辙病害处治技术研究现状和低标号沥青应用状况,采用某50号沥青,借鉴法国高模量沥青混合料设计方法体系,设计了抗车辙能力强、易压实、抗推移的混合料,工程应用表明该混合料适用于交叉口道面车辙快速处治,可为类似工程提供借鉴,也为50号沥青的应用拓展了思路。
In view of the present treatment technology research on ordinary arterial highway ＇s level - crossing pavements rut status and low grade asphalt application status, the paper used one kind of No. 50 as- phalt and borrowed from the French High - modulus asphalt mixture design method, designed a kind of mix- ture which had strong anti - rutting ability, easy compaction and resistant to shift performance. The engineering application indicated that this mixture was suitable for the rapid rutting treatment of level - crossing pave- ment. The research could provide reference for similar projects, and also expand the train of thought for the application of No. 50 asphalt.
