Water-permeable silica sand road shoulder
The invention provides a water-permeable silica sand road shoulder which comprises a water-permeable water-filtering silica sand surface layer, a bonding leveling layer, a rubble layer and a roadbed layer which are arranged from top to bottom, wherein the water-permeable water-filtering silica sand surface layer is used for water permeation and filtration through micro-sized silica sand pores; a micro-sized silica sand pore interface has a water-retention function. The water-permeable silica sand road shoulder has a relatively good water permeation effect.
