Construction method for reducing on-site cement cold regenerated mixture base cracks
The invention provides a construction method for reducing on-site cement cold regenerated mixture base cracks. The construction method comprises the following steps: I, preparing an expanding agent adopted for base construction of an on-site cement cold regenerated mixture, wherein the expanding agent comprises calcium sulfoaluminate, pulverized fuel ash and silica fume; II, blending the expanding agent in the step I with the on-site cement cold regenerated mixture in a certain proportion; and III, performing the base construction of the on-site cement cold regenerated mixture, and maintaining the road added with the expanding agent after the construction is completed. The overhigh expansion rate caused by excessive expanding agent is decreased, and further the problem that the expansion damaging phenomenon and the crack problem in the on-site cement cold regenerated mixture base layer due to dry contraction and temperature contraction can be avoided, and the performance of cement is improved to a certain extent.
