石灰与矿粉对建筑垃圾路基材料强度的影响研究

摘要

为了解决建筑垃圾稳定性能较差的问题,延长道路使用年限,采用无侧限抗压强度试验和水稳性试验方法,对石灰与矿粉稳定的建筑垃圾路基材料强度性能进行研究.研究结果表明:掺入石灰与矿粉明显有助于路基材料强度的提高,路基材料中石灰与矿粉的比例采用1:2比1:3更优;水养时,石灰与矿粉稳定的建筑垃圾路基材料强度略有下降,水稳性稍差.此研究结果对走出天然砂石材料日益枯竭的困境大有裨益,对缓解建筑垃圾围城的窘迫现状效果显著.%In order to solve the problem of poor performance of construction waste and prolong service life of road,the unconfined compressive strength test and the water stability test method were used to study the strength performance of lime and mineral powder stable construction waste subgrade material.Results show: Add in lime and mineral powder may greatly help improve strength of the road subgrade material,better adopting the lime and mineral powder proportion of 1:2 than 1:3;During curing,the strength of lime and mineral powder stable construction waste subgrade material was slightly down and the water stability was relatively worse.The results will greatly contribute to solving the difficult of shortage of natural sand & stone material,and ease the poor situation of cities surrounded by construction wastes.
