The temporary pavement material layer of vehicle pass-through, utmostly to prevent Construction traffic and road cement from blocking permeable pavement structure surface
Permeable " channel ".The traffic total amount of its thickness foundation construction period is within the scope of 12 to 20cm, according to lot of experimental data table
Bright, compression strength is greater than or equal to 20MPa, flexural tensile strength is not less than 2.5MPa；Through hole can be bored when surface construction so as to saturating
Water, for pore size control 5 to 10cm, excessive will affect can reduce this layer of bearing capacity, too small, should not fill rubble, influence to mat formation
There is weak spot in layer flatness；The rubble that nominal particle diameter is 1-2cm is filled in hole, the spacing of wells is not less than 3 with apart from roadside
Times aperture, spacing is smaller to generate the damage such as through crack.
Preferably, the thickness of the graded broken stone layer within the scope of 20 to 40cm, porosity 40%, partial size 2 to
5cm。
Preferably, the soil matrix is the native compacted lift of element, and the soil compaction degree of the native compacted lift of element is 93% or so.
Preferably, the screed-coat is coarse sands layer, and the thickness of the coarse sands layer is within the scope of 2 to 3cm and ballast grain sizes exist
Within the scope of 0.5 to 1cm.
Preferably, brick road face includes the muti-piece high intensity tile work mutually spliced, adjacent two blocks of high-intensitive tile works it
Between have 1 to 2cm permeable gap, the compression strength of the high intensity tile work is greater than or equal to 50MPa and flexural strength is not less than
5Mpa。
Preferably, the mutual composed pattern of tile work can be divided into three classes according to structural behaviour difference, herringbone pattern, parquets pattern
With running bond pattern.
Compared with prior art, the beneficial effects of the utility model are embodied in: the permeable tile work pavement structure, and design is closed
Reason, structure are simple.By the way that solid cement concrete layer is arranged, the bearing capacity on road surface is significantly improved, while as construction period
The current temporary pavement material layer of road vehicle, utmostly to prevent Construction traffic and road cement from blocking permeable pavement structure
Permeable " channel " on surface；And when last paved surface layer of material, it can punch on it, under allowing the rainwater of infiltration to continue
It seeps, guarantees enough rain penetration abilities, road surface not ponding, in below smooth discharge to road surface and surrounding greenery patches.
