Damping road structure and construction method thereof

Abstract

The invention discloses a damping road structure and a construction method thereof and relates to the technical field of road structures and construction. The damping road structure comprises an asphalt mixture paving layer, a precast concrete road board and a roadbed from top to bottom; a damping mortar layer used for damping is disposed between the precast concrete road board and the roadbed, awaterproof layer is disposed between the damping mortar layer and the roadbed, and insertion grooves and insertion heads are arranged on the side face of the precast concrete road board at intervals;the insertion grooves are inclined downward to the lower portions of the inner side of a board body of the precast concrete road board to form oblique surfaces, openings are formed in the lower ends of the insertion grooves, and the insertion heads are inclined downward to the lower portions of the outer side of the board body of the precast concrete road board to form oblique surfaces; every twoadjacent precast concrete road boards are connected with each other through the corresponding insertion grooves and the corresponding insertion heads. The problems that damping road structures are likely to be damaged and have a short life are solved, and a road can have great damping performance, a long service life and excellent bearing capacity.

Description

technical field [0001] The invention relates to the technical field of road structure and construction, in particular to a vibration-damping road structure and a construction method thereof. Background technique [0002] Due to the unevenness of the road surface and the self-vibration of the vehicle engine, the vehicle will have an impact on the road surface when driving, thereby exciting the entire road surface structure to vibrate. The generation of secondary noise affects people's work and life. Especially in the road forms such as roads inside or above the underground space, elevated bridge pavement structures, road sections with high requirements for vibration and noise reduction, or roads near important buildings, a vibration-reducing and vibration-isolating structure is required. road structure. [0003] In the prior art, the following methods are generally used to reduce the vibration of the road surface: one is to set the vehicle's own vibration damping system, bu...

AI Technical Summary

Problems solved by technology

Since the adjacent precast concrete road slabs are welded by steel bars, the relative position between the adjacent precast concrete road slabs is limited, when a single precast concrete road slab is vibrated, the vibration will be transmitted to the adjacent precast concrete road slabs, It will not be transmitted downward to the CA mortar layer. Once the vibration is too large, the welded part of the steel bar will break, and the connection between the adjacent precast concrete road plates will be disconnected, forming a height difference and causing cracks on the road surface.
