Abstract
The invention discloses a water proofing and draining combined type integrated draining system for a pavement. The system comprises an upper asphalt concrete surface layer, an asphalt adhering layer, a lower asphalt concrete surface layer, a draining base layer, a water proofing layer, an adhering layer, a subbottom layer, a first-grade broken stone blind ditch, a water collecting pipeline, a C25 concrete precast plate, a C25 cast-in-place concrete shoulder, a backfilling layer, a retaining belt, a second-grade broken stone blind ditch and an embankment stream trough. According to the water proofing and draining combined type integrated draining system for the pavement, a method in which the combination of an impermeable asphalt pavement layer and a permeable base layer is adopted is performed for achieving the integrated draining of the pavement, and therefore, the service life of the pavement can be prolonged.
Description
technical field [0001] The invention relates to a pavement comprehensive drainage system, in particular to an anti-drainage combined pavement comprehensive drainage system. Background technique [0002] As an open-air public facility, highways are subjected to multiple effects of the natural environment, and water damage is the phenomenon of damage to the pavement after precipitation enters the pavement structure layer. At the same time, water damage is one of the most common and most destructive diseases among the early diseases of asphalt concrete pavement. [0003] Usually, the sources of moisture on the road mainly include surface infiltration water, groundwater, capillary water action, seepage action, water vaporization, etc. Among them, the water infiltration on the surface of the road surface is more harmful and the most difficult to eliminate. Therefore, the infiltration of water into the pavement surface is the key point of road drainage design. A lot of research ...
