Grouting slurry and application thereof to cement stabilized gravel layer parting construction process

The invention provides grouting slurry in the cement stabilized gravel layer parting construction process. The cement stabilized gravel layer parting construction process can be completed by the following steps: performing joint cutting on a low fill road section, an arcing point in a road, a road filling and digging junction and a road centerline; filling the cut joint with slurry; and paving anti-cracking patch at the cut joint after crack pouring. In the process, a polyester cement mixture is provided and is particularly prepared from polyurethane or polyvinyl chloride cement, expanded graphite, bentonite or kaolin, coal ash and water. According to the technical scheme of the invention, a water stable layer parting construction method is applied, so that the repair rate of the road surface layer is reduced and the road surface layer does not have crack within the guarantee period. The cut joint is arranged on the water stable layer in advance before asphalt surface layer construction, and parting is arrang
