Problems solved by technology

[0005] The present invention aims to solve the problem that the packaging temperature is not easy to lose during asphalt transportation during the semi-flexible pavement construction process in the prior art, but the tarpaulins commonly used at present do not have multi-functionality and are easy to stick to asphalt. There

Abstract

The invention provides a semi-flexible pavement construction process and a quality control method, the construction process comprises the following steps: S1, paving a matrix asphalt mixture, S2, preparing cement-based adhesive cement, S3, pouring the cement-based adhesive cement, S4, curing, S5, opening traffic, and S6, treating a construction joint. According to the semi-flexible pavement construction process and the quality control method, the problems that in the prior art, in the semi-flexible pavement construction process, asphalt needs to be packaged during transportation, so that the temperature is not prone to loss, and tarpaulin which is commonly used at present does not have multifunctionality and is prone to adhering to asphalt, in the construction process, pouring of the cement mortar has certain defects, the discharging speed and the discharging amount cannot be controlled according to the actual situation in the moving process of a mixer truck, and the cement mortar conveyed in a discharging pipe all the year round is inconvenient to clean and prone to coagulation and blockage.

Description

technical field [0001] The invention relates to the technical field of pavement construction, more specifically, to a semi-flexible pavement construction process and quality control method. Background technique [0002] Semi-flexible pavement is a new type of pavement combining rigidity and flexibility. It has the advantages of good flexibility, strong crack resistance, no joints and cement concrete pavement, high rigidity, strong bearing capacity, and good anti-rutting performance of asphalt pavement. It is 1 / 5-1 / 2 of ordinary asphalt pavement, and its anti-rutting ability is more than 10 times that of ordinary asphalt pavement. It also has good water resistance, oil resistance, acid resistance and good colorability. It can be used for old The repair of ruts on the pavement can also be used for new pavement, and due to the long service life and reduced maintenance frequency, the social and economic benefits of the whole life cycle are remarkable. Composite with the flexi...
