在天然砂料中掺入适量的水泥、灰土和水,按照一定的技术要求拌均匀摊铺和压实,经过养护成型的基层称为水泥灰土稳定砂基层。 广东是多雨湿热地区,随着国民经济的发展,交通量不断增加,重型车辆增多,对公路路面的强度和耐久性提出了新的要求。经过近四年来的使用实践,我们认为水泥灰土稳定砂基层结构是可行的,是一种性能优良的基层材料,这种基层结构有如下优点: In the natural sand mixed with the right amount of cement, lime soil and water, according to certain technical requirements mix evenly paving and compaction, after curing the formation of the grass-roots level called the cement stabilized soil layer of sand. Guangdong is a hot and humid area. With the development of the national economy, traffic volume is increasing and heavy vehicles are increasing. New demands are put on the strength and durability of highway pavements. After nearly four years of practice, we believe that the cement-lime stabilized sand-based structure is feasible, is a good performance of the grass-roots materials, the grass-roots structure has the following advantages:
