Problems solved by technology

However, asphalt pavement construction needs to go through high-temperature processes such as mixing, transportation, paving, and rolling, and the construction equipment involved is complex and expensive; For road projects that are in short supply, narrow construction work area, strict environmental protection requirements on the construction site, or local disease treatment on the road surface, the application of asphalt concrete is greatly limited, and even construction cannot be carried out.
In addition, the asphalt pavement is porous and has high water permeability. In severe cold areas, frost heaving is obvious and the service life is low.

Abstract

The invention discloses a concrete structure assembly type pavement which comprises a concrete precast block formed by pouring reinforced concrete. Hexagonal patterns distributed in an array mode are distributed on the upper surface of the concrete precast block, each hexagonal pattern is composed of two guide lines with the same length and four friction resistance lines with the same length, the two guide lines are arranged in the front-back direction, a fixed included angle alpha is formed between the guide lines and the friction resistance lines, and the range of alpha is 110-130 degrees. The length ratio of the guide lines to the friction lines ranges from 1 to 2. The anti-freezing tire has the advantages of being simple in construction process, small in construction amount, convenient to lay, low in requirement for construction machinery, low in construction cost, convenient to maintain, low in maintenance cost, good in guidance quality, good in braking performance, small in friction resistance, small in tire noise, not prone to frost heaving, long in service life and the like.

Description

technical field [0001] The invention relates to the technical field of road and bridge engineering, in particular to a concrete structure assembled pavement. Background technique [0002] Asphalt pavement (asphalt concrete) has the characteristics of smooth surface without joints; comfortable and stable driving, low vibration and low noise; good surface skid resistance and high driving safety; main structural form. However, asphalt pavement construction has to go through high-temperature processes such as mixing, transportation, paving, and rolling, and the construction equipment involved is complex and costly. For road projects with shortage, narrow construction work surface, strict environmental protection requirements on the construction site or treatment of local road surface diseases, the application of asphalt concrete has been greatly limited, and even construction cannot be carried out. In addition, the asphalt pavement is porous, has high water permeability, obvio...
