Description
技术领域technical field
本发明属于建筑领域,尤其涉及到一种低温路面水稳基层混合料。The invention belongs to the field of construction, and in particular relates to a low-temperature pavement water-stabilizing base course mixture.
背景技术Background technique
水稳基层,其全称为水泥稳定碎石基层,是在具有一定级配的碎石中,掺入足量的水泥和水,经拌和得到的混合料在压实和养生后,当其强度符合规定的要求时,称为水泥稳定碎石基层。水泥稳定碎石基层具有良好的板体性,它的水稳性和抗冻性比石灰稳定土好,但常会因水分变化而引起干缩裂缝。而且在冬季温度低的条件下或者是高寒地带施工时,会由于低温而造成施工效果差。Water-stabilized base, its full name is cement-stabilized gravel base, which is mixed with a sufficient amount of cement and water in gravel with a certain gradation, and the mixture obtained after mixing is compacted and cured, when its strength meets When required by regulations, it is called cement-stabilized macadam base. Cement-stabilized macadam base has good plate properties, and its water stability and frost resistance are better than lime-stabilized soil, but it often causes shrinkage cracks due to moisture changes. Moreover, when the temperature is low in winter or in the alpine area, the construction effect will be poor due to the low temperature.
