The focus of attention in the construction process is always the quality of the project, the progress of safety (including environmental protection) and the cost.
A curb is a monument provided between a road surface and another structure. Curb stones are generally required to be arranged between a separation zone and a road surface of an urban road and between a sidewalk and the road surface, and the curb stones are usually required to be arranged at the edge of a central separation zone of a road, the edge of the right side of a traffic lane or the edge of the outer side of a road shoulder.
The existing kerbstones are generally in two forms, one is prefabricated by common concrete and the other is processed by stone materials, and the two forms are all waterproof materials. The foundation under the kerbstone is typically fine solid concrete, also a water impermeable material. Because the bottom layer of the pavement is a rammed foundation layer with larger thickness and is a watertight layer, and the kerbstone and the lower foundation are not pervious to water, the water in the pavement layer cannot seep downwards or is discharged through the kerbstone and the foundation. The water in the pavement structure layer and the interface between the surface layer and the base layer cannot be smoothly discharged out of the pavement structure, and is one of the causes of early damage to the pavement. Therefore, the existing kerbstone has the following defects: simple structure, poor strength, poor corrosion resistance and poor water seepage performance.
Therefore, it is highly desirable to provide a high-strength, corrosion-resistant and water-permeable curb structure with good overall strength, corrosion resistance and water permeability.
