Improved construction method of old cement concrete pavement
The invention provides an improved construction method of an old cement concrete pavement. The improved construction method comprises the following steps: disposing an old cement pavement disease and performing chiseling on the pavement surface; uniformly paving and spreading a layer of rubber modified emulsified asphalt mixture, and grinding on the old cement concrete pavement to form a crack inhibition function layer; paving a large-void asphalt mixture on the crack inhibition function layer; pouring cement mortar into the large-void asphalt mixture after the temperature of the large-void asphalt mixture is reduced to be under 50 DEG C, scraping the surface laitance with a brush to expose an aggregate structure after the large-void asphalt mixture is fully poured, and maintaining to open the traffic. The pavement constructed by the method can fully inherit the bearing capacity of the original cement concrete and has excellent anti-rutting performance and anti-fatigue performance, no lapped seam is formed on the pavement, the anti-sliding performance of the pavement is enhanced, the running safety is improved greatly and the improved construction method has wide application prospect.
