Problems solved by technology

[0008] The purpose of the present invention is to provide a shock-absorbing and compressive-resistant durable road with a shoulder-shaped pavement that can discharge water vapor generated underground, so as to solve the problem that the performance of the roadbed and pavement (the base layer in the pavement structure) is greatly reduced due to the muddying of the road, and the pavement is brittle from the surface. The problem of skin and collapse

Embodiment Construction

[0029] Attached below figure 1 The present invention is further described: the groove-type roadbed and the flat pole-shaped road surface shock absorption, compression and durability road are mainly composed of a groove-type roadbed surface, a flat pole-type solid strip-shaped roadbed surface and a road protection ventilation and diversion curbstone. It lies in the fact that the flat pole-type solid belt-shaped roadbed surface is seated on the groove-type roadbed surface, and the road kerbstone is fixed and protected to support the roadbed surface. Road ventilation and diversion kerbstones are provided with kerbstone ventilation holes.

[0030] The subgrade surface is in the shape of a concave arc flat pole, and the subgrade surface and the ground form an angle of 1.5% to 2% of the width of the road surface, and its compression resistance is several times that of the original subgrade surface.

[0031] The groove-type subgrade surface holds up the shoulder-pole-type solid belt...

Abstract

The invention provides a damping compression-resistant durable road with a groove type roadbed and a shoulder-pole type road surface, which relates to a damping compression-resistant durable road. The damping compression-resistant durable road mainly comprises a groove type roadbed surface, a shoulder-pole type entity banded roadbed surface and road-protection ventilate stream-guidance curbs. The damping compression-resistant durable road is characterized in that the shoulder-pole type entity banded roadbed surface is positioned on the groove type roadbed surface, the road-protection ventilate stream-guidance curbs are used for fixing, protecting and supporting the roadbed surface, a line passing hole is reserved on the shoulder-pole type entity banded roadbed surface, and curb ventilation holes are arranged on the road-protection ventilate stream-guidance curbs. The structures of the roadbed and the roadbed surface are stable; compared with the traditional structure, the stability is increased above 3 times, and the damping compression-resistant durable road has simple process and quantities and labor consumption reduction.

Description

technical field [0001] The invention relates to a shock-absorbing and compression-resistant durable highway, in particular to a shock-absorbing and compression-resistant durable highway with a groove-type roadbed and a pole-shaped pavement. Background technique [0002] With the rapid development of various industries in the society, the improvement of people's living standards, the increase of population and other factors, the means of transportation, transportation tools and construction vehicles that people need rushed to the road like a flood. The original old-fashioned curved eggshell and slab pavement structure design was not reasonable enough. The fragile curved eggshell pavement caused excessive overload and unbearable bearing capacity under the condition of overclocking and overloading, and it was crushed under the rolling of passing vehicles. , crushing, deformation, bumps and pulping and other serious damage, resulting in poor driving, traffic jams, avoidance and ...
