High-strength pervious concrete pavement structure and application thereof

Abstract

The invention discloses a high-strength pervious concrete pavement structure and application thereof. The high-strength pervious concrete pavement structure comprises a base layer, a bearing layer and a high-strength reactive powder concrete layer which are sequentially arranged from bottom to top, and the high-strength reactive powder concrete layer is a small-pore pervious layer. The high-strength reactive powder concrete layer contains reactive powder so that the powder is tightly stacked, reasonably and compactly filled, a high-strength cement matrix is formed, the porosity of cement paste is reduced, the microstructure of pervious concrete and bonding among aggregates are improved, and when the high-strength reactive powder concrete layer is applied to a road surface, water permeation is facilitated, the blocking of leaves, branches, garbage and the like can be effectively blocked, the bearing layer can transfer the upper load, and the overall strength of the pavement structure is improved. The invention further discloses application of the high-strength pervious concrete pavement structure to sidewalks, bicycle lanes and outdoor parking lots.

Description

technical field [0001] The invention relates to the technical field of municipal construction, in particular to a high-strength permeable concrete pavement structure and its application. Background technique [0002] In recent years, the roads in cities are no longer the dirt roads they used to be, but have been replaced by cement asphalt and other roads, and these roads are often paved with water-blocking materials, so these roads are impermeable and will break down under certain circumstances. Bring adverse effects to the ecological environment of the city. Permeable concrete is a green and environmentally friendly material. It is a porous concrete made of aggregate, cement and water. It does not contain fine aggregate. The surface of the coarse aggregate is covered with a thin layer of cement paste to bond with each other to form a uniform distribution of pores. The honeycomb structure has the characteristics of air permeability, water permeability and light weight, whic...
