Abstract

The invention discloses a concrete road. The concrete road is formed by laying a base layer and a wear-resistant layer, wherein the wear-resistant layer is directly applied on the base layer, the baselayer is a concrete base layer, the wear-resistant layer is a permeable concrete layer modified by a polymer elastomer, the thickness of the permeable concrete layer is less than 4 centimeters, the void content is 5%-20% of the volume, the optimized void content is 5%-10% of the volume, and the largest diameter of an elastomer aggregate which exists in the permeable concrete layer modified by theelastomer is 10 mm. According to the concrete road, the mechanical performance is good, the bending/compressive strength ratio is high, compared with traditional permeable concrete, the concrete roadhas higher anti-fouling capability and high bonding strength, slip resistance and drainability, and multiple aspects of performance of the concrete road are close to the performances of a bituminouspavement, while the cost is far lower than the cost of the bituminous pavement.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular, the invention relates to a concrete road. Background technique [0002] Compared with asphalt concrete pavement and concrete pavement, the advantages and disadvantages of the two are as follows: 1. Asphalt pavement is a flexible pavement, which is comfortable to drive and has low noise; as a rigid pavement, cement concrete pavement is not as comfortable as asphalt pavement. The setting of expansion joints also affects driving comfort. In addition, asphalt concrete is relatively easy and fast to repair after partial damage, and the impact on traffic is short; cement concrete is difficult to remove after local damage due to its high strength. The surface of asphalt concrete pavement is rougher, and its anti-skid ability is stronger than that of smooth cement concrete pavement. It is not easy for cars to skid in rainy days, and the braking distance is relatively shor...
