摘要
随着道路建设发展,冻融循环地区基层材料耐久性受关注。本文聚焦此问题,分析常见基层材料受冻融影响的性能变化,探讨抗压、抗折强度改变及水稳定性差异,对比不同材料耐久性优劣,为道路设计、施工选材提供依据,助力提升冻融区道路寿命。
Abstract
As road construction advances, the durability of subgrade materials in freeze-thaw cycles has gained attention. This paper focuses on this issue, analyzing the performance changes of common subgrade materials under freeze-thaw effects, exploring differences in compressive and flexural strength as well as water stability. It compares the durability advantages and disadvantages of different materials, providing a basis for road design and material selection during construction, thereby enhancing the lifespan of roads in freeze-thaw zones.
