Embodiment Construction

[0027] A construction method for the asphalt wave road of the first phase expansion project of Shanghai Volkswagen Proving Ground, which specifically includes the following steps:

[0028] (1) Determination of the sine function of the asphalt wave road surface

[0029] According to the pavement sinusoidal curve parameters given in the design documents, the sinusoidal function is obtained, and the encrypted three-dimensional coordinates of each site are calculated by computer;

[0030] (2) Lime soil subgrade and graded crushed stone filling

[0031] First, excavate the road trench and fill it with lime soil, then set the control mileage in the longitudinal direction of the line according to the curve of the wave road, and set fine-adjustable steel wire rope brackets on both sides of the road at the control mileage, and use the steel wire rope as the elevation reference for paving , precisely adjust and lock the elevation of the steel wire rope at each control point, and then u...

Abstract

The invention discloses a construction method of asphalt wave roads, the method comprises the following steps: calculating sinusoidal function according to a sine curve parameter given by a designed file, calculating each on-site encrypted three dimensional coordinate by a computer, selecting elevation datum paved by asphalt by establishing a calculation model, completing the construction of roadbed and base course, paving the parts below a surface layer on the case course, then paving an asphalt mixture to form an asphalt surface layer, successfully finishing the final molding of the asphaltwave roads. The construction method of the invention is capable of greatly raising the quality of pavement construction and effectively guaranteeing the standard performance of asphalt wave pavement molding.

Description

technical field [0001] The invention relates to a road construction method, more specifically to a construction method for asphalt wave roads used in special occasions. Background technique [0002] Asphalt wavy roads are the requirements for road surfaces in some special occasions. For example, the asphalt wavy road of the first phase expansion project of Shanghai Volkswagen Proving Ground includes 5 special longitudinal wavy roads, namely Stucker wavy road (200m long), Changbo road (long 100m), medium wave road (length 80m), short wave road 1 (length 70m), short wave road 2 (length 50m) wave curves are all sine waves. Curb stones are used to control the elevation of asphalt paving for wavy road paving, which is easy to operate. With the continuous maturity of domestic automobile test tracks and the continuous improvement of market requirements for motor vehicle performance, arched uneven roads will be used in each test track . [0003] So far, there is no public report a...
