Description
Technical field
The present invention relates to a kind of drainage pavement pore plugging prior-warning device, belong to porous asphalt pavement performance monitoring equipment.
Background technology
Porous asphalt pavement makees top layer using Asphalt mix for open-graded friction course, rainfall is penetrated into drain function layer, and pass through
Rainwater is laterally discharged in layer, so as to eliminate the road table moisture film for bringing many driving detrimental effects, significantly improves rainy day driving
Security, comfort, drainage asphalt pavement, which has, to be reduced water mist and dazzle, reduces noise, waterproof drift, improves pavement marker
Visibility and improve wet road surface skid resistance the advantages that, be a kind of high-performance, high-quality Pavement Structure, at present
By multinational extensive use.China just in the construction in Efforts To Develop " sponge city ", porous asphalt pavement rainwater water suction, ooze
Water, diversion, draining link can play an important role, and have vast potential for future development.
Porous asphalt pavement has good saturating, drainage performance at the initial stage of building up, but with the extension of service life, draining
The drainage performance of bituminous paving can be gradually reduced, and tracing it to its cause mainly has two aspects, first, porous asphalt pavement is in passing car
Roll repeatedly under, part hole gradually cave in addition close；Second, sand and dust debris etc., which gradually blocks hole, causes road surface
Drain function reduces.Drainage pavement hole needs to carry out maintenance of surface to it immediately if blocking, and maintenance process is typically
Hole is washed away with high pressure water and compressed air or vacuum pump suctions out debris.
Determine when that carrying out drain function to porous asphalt pavement recovers to be the important step conserved.Curing time
It will cause the unnecessary waste of maintenance fund, curing time too early can not then play the effect of drainage pavement, cause road too late
Area water.It is most of by establishing draining at present for differentiating that the method whether porous asphalt pavement internal void blocks is seldom
Road surface model combination laboratory test carries out estimating for duration of congestion, natural environment and friendship due to porous asphalt pavement location
Logical environment is multifarious, and such a method practical application effect of getting up is poor, can not accurately determine the duration of congestion of hole, and then lead
Cause road maintenance department can not propose effective Maintenance Decision making.
The content of the invention
