早期修建低等级公路路面结构大修设计技术研究

摘要

结合早期修建的低等级公路路面结构设计情况和使用状况,在充分考虑利用旧路路面结构剩余强度、降低大修工程建安费和保证路面使用寿命等的技术思路上,提出了路面结构大修设计方案、水稳层顶面弯沉控制标准.%According to the early construction of the low grade highway design and usage situation, Technical ideas based on the use of the old road surface structure residual strength、 reduce the overhaul engineering construction and installation cost and ensure the service life of the pavement, and the pavements design schemes and the standard of flexture value of the stable layer are put forward. Provide technical reference for similar engineering.
