Embodiment Construction

[0052] In order to ensure that the asphalt mixture on both sides of the expansion joint has sufficient compaction, the upper asphalt concrete is normally constructed after the concrete backing plate at the outer road end of the tunnel is pre-buried, and the mixture at the location of the expansion joint is removed when the expansion joint is installed. The specific steps for the installation of the mauler seam are as follows:

[0053] 1.) Slit slotting

[0054] ① On the pavement that has passed the inspection, draw the edge markings corresponding to the original reserved position. The markings should be straight and parallel to the axis of the expansion joint, but at the same time, avoid the distance between the markings being smaller than the width of the groove. The range of ~3mm is better, the reason is to prevent the settlement and deformation of the edge of the road surface during the installation process.

[0055] ② After the marking line is confirmed to be qualified, t...

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 relates to a method for treating the end of a concrete highway pavement, in particular a method for easily solving the end treatment of a continuously reinforced concrete pavement, and belongs to the technical field of highway 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 dry shrinkage, the concrete slab needs to be equipped with transverse joints 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 give The use brings many disadvantages, such as low load transfer capacity and poo...
