Abstract

The invention discloses an internal drainage system of a pavement structure capable of excluding water seepage from the road surface, comprising a fine-grained modified asphalt concrete AC-13C layer, an SBS modified asphalt bonding layer, a medium-grained asphalt concrete AC-20C layer, and a porous modified asphalt concrete layer. Permanent concrete base, waterproof layer, adhesive layer, cement-stabilized graded crushed stone subbase, C25 concrete prefabricated slab, C25 cast-in-place concrete shoulder, graded crushed stone blind ditch, soil layer and pipes. The invention is equipped with graded crushed stone blind ditch, which can quickly realize the discharge of seepage water on the road surface.

Description

technical field [0001] The invention relates to a pavement drainage system, in particular to an internal drainage system of a pavement structure capable of eliminating water seepage on the road surface. Background technique [0002] In recent years, my country's transportation industry has developed rapidly, and the construction of highway network has become more and more perfect. However, as an open-air public facility, the highway is bound to be affected by multiple effects of the natural environment. Water damage is the phenomenon of damage to the pavement caused by precipitation entering the pavement structure layer. one of the diseases. [0003] Usually, the sources of water that need to be drained on roads mainly include surface infiltration water, groundwater, capillary water, seepage, and water vaporization, among which surface infiltration water is the main source of pavement water. Therefore, rapid drainage of road surface water is the key to road drainage design...
