Embodiment Construction

[0051] In order to ensure sufficient compaction of the asphalt mixture on both sides of the expansion joint, the upper asphalt concrete shall be normally constructed after the concrete pads on the outer pavement end of the tunnel are pre-buried, and the mixture at the location of the expansion joint shall be removed when the expansion joint is installed. The specific steps of Maurer seam installation are as follows:

[0052] 1.) Cutting and slotting

[0053] ① On the road surface that has been tested and qualified, draw the edge markings to be grooved corresponding to the original reserved positions. The markings should be straight and parallel to the axis of the expansion joint, but at the same time, avoid the spacing between the markings and the groove width. The range of ~3mm is better because it prevents the edge of the road from settling and deforming during installation.

[0054] ②After the marking line is confirmed to be qualified, the asphalt concrete surface layer can be ...

Abstract

The continuously reinforced concrete pavement end processing method is easy to treat the continuously reinforced concrete pavement end. Its special steps are as follows: 1) cutting seam and slotting. 2) Clearing preset slot. 3) Transportation and installation. 4) Welding. 5) Pouring cement concrete. 6) Embedding maurer expansion joint sealing rubber belt. With the good performance of the maurer expansion joint, it has advantages of wear resistance, antiskid, waterproof, good anti-aging performance, small vibration, no noise, long service life and easier maintenance etc.

Description

Technical field [0001] The invention is a method for the end treatment of concrete road pavement, in particular to a method that is easier to solve the end treatment of continuous reinforced concrete pavement, and belongs to the technical field of road pavement construction. Background technique [0002] Cement concrete pavement is one of the main types of high-grade highway pavement structure. Compared with asphalt pavement, it has the advantages of high bearing capacity, durability and less maintenance. It has been gradually promoted in my country since the 1980s. In order to reduce the damage caused by temperature shrinkage and drying shrinkage, the concrete slab needs to be equipped with transverse and longitudinal joints. The joints are the weak points of the cement concrete base. These joints will not only increase the complexity of concrete pavement construction, but also The use brings many disadvantages, such as low load transfer capacity and poor flatness at the joints,...
