Using above-mentioned technical proposal, plastic coat is irradiated the gas that can give out peculiar smell be subject to sunlight for a long time, passes through
Absorption of the adsorbent to gas with foreign flavor reduces gas with foreign flavor distributing into air, and then increases what plastic cement race track used
Suitability.
Preferably, the adsorbent is activated carbon layer.
Using above-mentioned technical proposal, by absorption of the activated carbon layer for smell product, gas with foreign flavor is reduced to air
It distributes, in addition, activated carbon layer can be filtered the water permeated downwards by plastic coat, and then to being flowed into runway from hydrophobic layer
Water in the drainage pipeline of both sides carries out pre-filtering, reduces the pollution for interflow subsurface drainage water.
Preferably, expansion joint is offered in the base.
Using above-mentioned technical proposal, when sunlight scorches plastic cement race track, base can expand because temperature raises,
By expansion joint, destruction of base's expansion upheaval for each structure sheaf on base is reduced, further increases plastic cement race track
Durability.
Preferably, pitch filled layer is filled in the expansion joint.
Using above-mentioned technical proposal, when base shrinks due to temperature reduces, expansion joint is filled in by pitch filled layer,
Pitch filled layer applies pulling force to the bases of both sides, reduce the excess shrinkage of base and by the possibility of waterproof layer drawing crack.
In conclusion the utility model has the advantages that：
1. by setting hydrophobic layer between elastic layer and waterproof layer, increase the draining gas permeability of plastic cement race track, and then in time
The water of the elastic layer of infiltration is drained, extends the service life of plastic cement race track, increases the durability of plastic cement race track；
2. by setting thermal insulation layer between waterproof layer and hydrophobic layer, reduce waterproof layer influences waterproof effect due to excessive tensile
Fruit, enhance plastic cement race track use use adaptability；
3. setting adsorbent between plastic coat and elastic layer, inhaled for the gas with foreign flavor of plastic coat diverging
It is attached, peculiar smell smell distributing into air is reduced, increases the suitability that plastic track uses.
