Problems solved by technology

However, the material of the mesh permeable aqueduct is different from that of the substrate layer, and the connection effect between the two gradually deteriorates with the prolongation of the service life, and the installation appears to be separated, which makes it difficult for the water in the permeable substrate layer to be discharged smoothly

Abstract

The invention discloses a road surface paving plate with a waterproof surface layer and a permeable base layer, and a production technology thereof. The road surface paving plate comprises a surface layer and a base layer, wherein the surface layer contains the following raw materials in parts by weight: 14-28 parts of water, 20-30 parts of cement, 10-15 parts of slag, 6-8 parts of coarse whiting,0-2 parts of metakaolin, 32-42 parts of fine sand, 1-2 parts of poval, 0.1-0.2 parts of tartaric acid, 0.01-0.02 parts of tri-isopropanolamine, 1-1.5 parts of pure acrylic emulsion, 0.05-0.1 parts ofcellulose ether, 1-1.5 parts of emulsion powder, 0.3-0.5 parts of first additive, 6-8 parts of water, 16-18 parts of cement, 4-6 parts of coal ash, 41-47 parts of macadam, 16-21 parts of coarse sand,0.05-0.1 parts of xanthan gum, and 0.2-0.4 parts of second additive. The road surface paving plate has the advantages of being excellent in waterproofness of the surface layer and permeability of thebase layer, and beneficial to smooth drainage after the road surface paving plate is arranged.

Description

technical field [0001] The invention relates to the technical field of paving slabs, more specifically, to a pavement paving slab with an impermeable surface layer and a water-permeable base layer and a manufacturing process thereof. Background technique [0002] The impermeability of pavement slabs is poor, and rainwater easily seeps into pavement slabs, and accumulates in the gaps formed after assembling pavement slabs over time, causing the laying of pavement slabs to become uneven. During the driving process, water splashes are prone to occur. [0003] The Chinese patent with the authorized announcement number CN206521660U and the authorized announcement date of September 26, 2017 discloses a water-permeable pavement pavement, including a water-permeable finish layer and a water-permeable substrate layer, and the water-permeable finish layer is installed on the water-permeable substrate layer On the above, the substrate layer is built with a reinforced fiber layer and a...
