摘要
石灰粉煤灰三渣作为路基基层,已被广泛应用。该文针对某项目的个别标段的路基基层,出现不均匀的起伏和沉陷现象,以及路面多处出现沥青混凝土破损的问题,做了初步的分析,并建议加强对SO3和游离氧化钙予以控制。
Three dregs of lime fly ash taken as the roadbed has been widely used.The article preliminarily analyzes the asymmetric waving and cave phenomena of the roadbed in a bidding section of a project,and the damaged asphalt concrete at many pavements,and suggests to strength the control of SO3 and free calcium oxide.
