本文介绍了第十八届世界道路会议关于半刚性路面讨论会的情况。详细叙述了半刚性的定义,用水硬性结合料或火山灰质结合料处治的目的,材料的组成、配制及设计方法,半刚性路面基层之裂缝的形成及其减小方法。同时阐述了单层或多层水硬性结合料处治层的结构设计方法和养护、修复等问题。本文对我国正在试验、推广的半刚性路面设计和施工都有一定参考价值。由于半刚性路面在世界范围的重要性,十七届世界道路会议柔性路面委员会报告的第九章中讨论过这种结构。1987年9月在布鲁塞尔召开的十八届世界道路会议上由柔性路面技术委员会和刚性路面委员会联合举行了一次有关这种结构的讨论会。本文件是这次讨论会的一个初步报告。
This article presents the eighteenth session of the World Road Conference on semi-rigid pavement. The definition of semi-rigid, the purpose of the treatment with hydraulic binder or pozzolanic binder, the composition of the material, the preparation and design method, the formation of the cracks in the semi-rigid pavement base and the way to reduce it are described in detail. At the same time, the structural design methods, maintenance and repair of the single or multi-layer hydraulic binder are described. This article has some reference value to the semi-rigid pavement design and construction which our country is testing and popularizing. Due to the worldwide significance of semi-rigid pavements, this structure was discussed in Chapter IX of the report of the Flexible Pavement Committee for the 17th World Roads Conference. A symposium on this structure was jointly held by the Technical Committee for Flexible Pavements and the Rigid Pavement Commission at the 18th World Roads Conference in Brussels in September 1987. This document is a preliminary report of this seminar.
