山区高速公路风化岩路基填料工程特性及施工关键工艺研究

青质料、黄质料、灰质料和隧道石是四种具有不同风化程度的填料.击实试验结果揭示经击实所形成的结构与粒料组成、含水量等因素的相关关系.击实前后粒料级配的变化分析可揭示其破碎性.风化石料施工应采用与一般填料不同的控制指标.

Engineering Properties and Key Construction Technology of Weathered Rock Subgrade Fillers in Hill Expressway

Green material, yellow material, gray material and tunnel rock are four kinds of fillers with different weathering degrees. The compaction test results discovere the relationship of compacted structure with the factors of granular composition and water content. Analysis on the aggregate gradation change before and after compaction can reveal its crushing. Weathered stone construction is ought to use control indexes different with common fillers.
