水泥粉煤灰稳定碎石基层施工工艺

Construction Technique of Cement-fly-ash Stabilized Macadam Base

水泥粉煤灰稳定碎石基层作为一种新型的半刚性基层类型,具备水泥稳定类和二灰稳定类材料的优点,并摒弃了两者的缺点,具有早强、高强、减少裂缝、提前开放交通、后期强度仍有较大增长的特点,有利于满足日益增长的交通需求特别是重载交通的需求。

As a new type of semi-rigid base, cement-fly-ash stabilized macadam base possesses the advantages of cement stabilized materials and fly-ash stabilized materials, meanwhile eliminates the disadvantages of the two. Cement-fly-ash stabilized macadam base has such characteristics as earlier strength, higher strength, less cracks, being open to traffic in advance, greater increase of anaphase strength, which helps to meet the demand of increasing traffic volume, especially the over loading traffic.
