Abstract

The invention relates to an asphalt concrete pavement 3D paving construction method. The method includes the following steps that construction is prepared; a construction segment is determined; a three-dimensional digital model of the construction segment is established; laser emitter control points are distributed; design elements of a paved face are determined, and the longitudinal slope of a paved region and the design elevation of a paved belt start point are calculated according to design requirements; laser emitters are installed according to the position of a paved belt, the design elements of the to-be-paved region are input into the laser emitters, and the paved face accuracy set in the laser emitters is detected and checked; a paver and paver parameters are established; the control points, paved face information and laser receiver and laser emitter data are input into a control system, and the control system determines the height of a distributor of the paver; and paving is organized to be implemented. By the adoption of the asphalt concrete pavement 3D paving construction method, the parameters such as the paving thickness, the paving width and the pavement elevation inthe asphalt concrete pavement paving construction process are accurately and automatically controlled.

Description

technical field [0001] The invention belongs to the technical field of highway engineering, in particular to a construction method for 3D paving of asphalt concrete pavement. Background technique [0002] Paving technology is one of the important contents of asphalt pavement construction in highway engineering, and its technical level directly affects the overall quality of the project. At present, in the process of asphalt pavement paving construction, the measurement and setting out of the middle and side piles is the main work content of the measurement before the paving construction. The section design coordinates and the design elevation are separated by 10m. shop. In order to effectively control the elevation error of the base layer, it is necessary to select the overall floating reference beam of the asphalt paver and the construction joint method to carry out the construction of the upper layer and the lower layer of the paver walking reference line. Tension steel ...
