山渣料工程性质的研究

基于山渣料具有强度特性、变形特性、风化程度等变异性大的特点,公路建设中对其工程特性缺乏系统地认识。针对西汉高速公路山渣料应用现状,取样进行了室内击实、压缩、浸水破碎试验及现场试验检测研究。结果表明,山渣料最大干密度、压缩模量与粗粒含量有关,粗粒含量小于一定值时,最大干密度、压缩模量随着粗粒含量的增加而增加。山渣料水稳性较好,现场压实施工时松铺厚度以不超过40 cm为宜。

Study on Engineering Property of Rock Slag Mixture

Because of the dear systematically variability of strength, deformation, efflorescence of rock slag mixture, its engineering property has not been systematically studied. Directed against the applied status of the rock slag mixture in XI- HAN expressway, tests were carried out to study the indoor compaction, compression, crashing in water and the field detection of the rock slag mixture. The test results show that the biggest dry density and compression module are related to the coarse material content, and when the coarse material content is less than a certain value, the biggest dry density and compression module increase with the increasing of the coarse material content. The rock slag mixture has good stability in water, and the loose thickness is less than 40 cm.
