吹填砂在水泥稳定碎石层中的应用

Application of Hydraulically Reclaimed Sand in Cement Stabilized Crushed Stone Course

在曹妃甸矿石码头一期堆场工程的水泥稳定碎石层的级配设计中,依据嵌挤原则和密实骨架的特点,因地制宜,就地取材,使用堆场吹填砂作为混合料的填充料,经过室内专题试验和工程实际应用证明,吹填砂在水泥稳定碎石层中的应用方案可行,具有明显的经济效益。

During the gradation design of the cement-stabilized crushed stone course for the first phase of the stacking yards for Caofeidian Ore Terminal, based on the principle of wedging and the characteristics of dense skeleton and by adjusting measures to local conditions and getting raw materials from local resources, the hydraulically reclaimed sand in the site for the stacking yards was used as the filling material. Laboratory tests and field use of the material showed that it is feasible to use hydraulically reclaimed sand in cement stabilized crushed stone courses and produces significant economic benefits.
