According to above-mentioned technical proposal, the pervious asphalt layer is that nominal maximum particle diameter is that 16mm or 20mm open gradation pitches mix Material is closed, voidage is 15~20%.

According to above-mentioned technical proposal, the thickness of pervious asphalt layer is 50-80mm.

According to above-mentioned technical proposal, described grading slag aggregate water conservation layer is that nominal maximum particle diameter is 25mm or 30mm Grading slag aggregate.

According to above-mentioned technical proposal, the thickness of grading slag aggregate water conservation layer is 200~400mm.

According to above-mentioned technical proposal, the drainage layer is natural sand or slag fine aggregate or recycled fine aggregate.

According to above-mentioned technical proposal, the thickness of drainage layer is 20~40mm.

According to above-mentioned technical proposal, the soil matrix layer is compacted soil, and the compacting factor of compacted soil is more than 95%, soil matrix layer Thickness be 200~300mm.

The utility model has the advantages that：

Water-permeable colored asphalt surface course, pervious asphalt layer, grading slag aggregate water conservation layer, the drainage from top to bottom set gradually Layer and soil matrix layer, each structure sheaf are respectively provided with preferable water penetration, and rainwater can permeate rapidly, avoid the formation of rainwash, simultaneously Rainwater directly infiltrates into soil horizon, recharge of groundwater, maintains the underground ecological balance；Grading slag aggregate water conservation layer employs slag Aggregate, because slag possesses loose structure, makes the structure sheaf have compared with general graded broken stone layer excellent as moisture structure layer Different water retention property, moisture can be discharged in dry conditions, the moisture in soil and air is supplemented, have obvious " sponge " adjustment effect；Water-permeable colored asphalt surface course uses porous color bituminous paving as superficial layer, more permeable than in general mixed What solidifying soil surface had ride and walking comfort；The double-layer porous pitch that water-permeable colored asphalt surface course and pervious asphalt layer is formed Pavement structure has excellent sqouynd absorption lowering noise performance, shows according to domestic and international research, can reduce by 3~5dBA of city noise, especially suitable Together in the low load pedestrian such as vast park, cell, green road or non-motor vehicle road.

Brief description of the drawings

Fig. 1 is the schematic diagram for the colored road structure thoroughly of low load for being applied to sponge city in the utility model embodiment；

In figure, 1- colorful water-permeable asphalt uplayers, 2- pervious asphalt cutting optimals, 3- grading slag aggregate water conservation layers, 4- filters Water layer, 5- soil matrix layers.

Embodiment

The utility model is described in detail with reference to the accompanying drawings and examples.

Shown in reference picture 1, the low load in a kind of embodiment provided by the utility model applied to sponge city is colored thoroughly Road structure, including water-permeable colored asphalt surface course, pervious asphalt layer, the grading slag aggregate water conservation from top to bottom set gradually Layer, drainage layer and soil matrix layer.

Further, the water-permeable colored asphalt surface course is the OGFC that nominal maximum particle diameter is 10mm, The voidage of OGFC is 15~20%.

Further, described water-permeable colored asphalt surface course is prepared using transparent cementitious matter, and adds pigment, pigment color It can be one kind in red, green, yellow, and not limit to and above color.

Further, the thickness of water-permeable colored asphalt surface course is 30-40mm.

Further, the pervious asphalt layer is that nominal maximum particle diameter is 16mm or 20mm open gradation asphalts, empty Gap rate is 15~20%.

Further, pervious asphalt layer uses modified pitch or rubber asphalt as cementitious matter.

Further, the thickness of pervious asphalt layer is 50-80mm.

Further, described grading slag aggregate water conservation layer is that nominal maximum particle diameter is 25mm or 30mm grading slag Aggregate.

Further, because slag has loose structure, this structure sheaf has the work(of water-absorbing-retaining while porous Can, make pavement structure that more there is " sponge " effect.

Further, the thickness of grading slag aggregate water conservation layer is 200~400mm.

Further, the drainage layer is natural sand or slag fine aggregate or recycled fine aggregate.

Further, the thickness of drainage layer is 20~40mm.

Further, the soil matrix layer is compacted soil, and the compacting factor of compacted soil is more than 95%, and the thickness of soil matrix layer is 200~300mm.

In one embodiment 1 of the present utility model：

This structure includes surface layer, grading slag aggregate water conservation layer, drainage in colorful water-permeable asphalt uplayer, pervious asphalt Layer, soil matrix layer.

The OGFC-10 compounds that colorful water-permeable asphalt surface course is prepared using modified transparent cementitious matter, voidage 20%, mix Add the ferric oxide red colorant of mixture quality 2%, thickness 30mm；Surface layer is prepared using SBS modified pitch in pervious asphalt OGFC-16 compounds, voidage 20%, thickness 50mm；Grading slag aggregate water conservation layer uses Wuhan Iron and Steel Plant slag, nominal maximum Particle diameter is 30mm, thickness 400mm；Drainage layer uses slag fine aggregate, thickness 30mm；Soil matrix layer is compacted soil, compacting system Number is more than 97%, thickness 300mm.

In summary, compared with Traditional Landscape is mated formation, each structure sheaf is respectively provided with preferable water penetration in this structure, and rainwater can Rapid infiltration, the formation of rainwash is avoided, while rainwater directly infiltrates into soil horizon, recharge of groundwater, maintains underground ecology Balance；Slag aggregate is employed in this structure sheaf as moisture structure layer, because slag possesses loose structure, make the structure sheaf with General graded broken stone layer can discharge moisture in dry conditions, in soil and air compared to having excellent water retention property Moisture is supplemented, and has obvious " sponge " adjustment effect；This structure uses porous color bituminous paving as surface layer, than one As riding of having of pervious concrete pavement and walking comfort；The double-layer porous asphalt pavement structure of this structure has excellent Sqouynd absorption lowering noise performance, show according to domestic and international research, 3~5dBA of city noise can be reduced.

The power for being only preferred embodiment of the present utility model, the utility model can not being limited with this certainly above Sharp scope, therefore the equivalence changes made according to present utility model application the scope of the claims, still belong to the scope of protection of the utility model.
