摘要:
通过一系列室内试验包括液塑限实验、击实试验、强度试验、收缩实验以及稳定性实验,研究了水泥再生灰土材料石灰稳定细粒土的材料组成设计及其路用性能,研究了旧路面底基层材料石灰、水泥或二灰稳定类细粒土是否可以通过冷再生技术获得重新利用.由试验数据可看出,用水泥稳定旧路面灰土材料与典型半刚性材料相比具有类似的物理特性,同时也发现冷再生旧路面材料有很好的路用性能,可以用于道路底基层.这一研究对于合理综合利用废旧路面材料,使经济效益和社会效益共同最大化,对我国环境保护也有深远意义
Abstract:
Concrete sorption capacity is an important index of durability appraisal. The theory and measurement of capillary suction in the concrete were introduced. The effect of water-cement ratio, drying temperature, submerged depth, environmental temperature and relative humidity on sorption capacity in the concrete were investigated by the capillary rise test. The test results showed that water-cement ratio and drying temperature had significant effects on concrete sorption capacity. The submerged depth below 5mm had little effect on it. The increase of the environment temperature and relative humidity could promote the concrete sorption capacity. The sensitivity of the environmental temperature on the sorption capacity was higher than that of the relative humidity
