Low city noise；The road surface porosity that polyurethane rubble is laid with is direct with rainfall up to air pollutants such as 30% or so, PM10
Permeate the ground and permanently seal up for safekeeping, thus will not reentrainment of dust, effectively control dustiness dye the problem of；Polyurethane macadam pavement makes full use of respectively
The true qualities of kind lithotome, can keep for a long time color constant, convenient for moulding coloury road surface pattern.This is a kind of ideal
Road surface landscape pavement material can be widely used in the facilities such as town road, town and country Lv Dao, park plaza, station terminal, have wide
Wealthy application prospect is of great significance to the improvement of urban ecological environment.But the country is on the permeable road of polyurethane rubble at present
Corresponding professional standard not yet in terms of face design and construction, when pavement construction, rely on the experience of construction company to carry out mostly, lead
Porous pavement is caused to there is more hidden danger of quality in the construction process.
Summary of the invention
To solve problems of the prior art, the present invention provides a kind of polyurethane broken stone water permeability pavement construction parties
Method, the construction method of the invention compacting machine road pavement before mixture is fully cured are compacted, are polished, and road surface is able to ascend
Finish and flatness；After mixture is fully cured, the extra polyurethane adhesive on abrasive disk road pavement surface layer is used
Stick carries out polishing except glue, while road pavement has also carried out anti-skidding processing, enhances the antiskid effect on road surface.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of polyurethane broken stone water permeability pavement construction method, comprising the following steps:
S1, rubble and adhesive are carried out to prepare mixture with when stirring；
S2, the mixture prepared in step S1 is paved, forms road surface；

His partial size) all can, dust content account for the griotte below of total weight 0.4 ‰ because the ballast grain sizes that can be bought on the market be by
Particle size range classification, be not by grain size grading, it is impossible to buy the rubble that partial size is entirely 3mm or 5mm, what is bought is exactly
One particle size range, and it is suitable for the present embodiment in this particle size range, therefore in embodiment not with specific partial size
Numerical value is defined.
Live drying is carried out to rubble before proportion stirring, it is high to carry out drying degree of making it dry to rubble, has used
The rubble of white drying has great promotion to the quality on road surface after molding, because mixture has moisture content in the curing process
When, polyurethane adhesive can foam, and will lead to pavement cracking, fragmentation, and the moisture content avoided in mixture influences pavement quality, gather
Urethane adhesive uses common xanthochromia glue or color inhibition glue, and polyurethane adhesive divides component A and B component, common xanthochromia glue
The mass ratio of component A and B component (6551 C-B of Elastopave C 6551/202 C-A and Elastopave C) is in water
100:65, component A and B component (6550/100 C-A of Elastopave C and Elastopave C 6550/ in color inhibition glue
100 C-B) mass ratio be 40:100.).In the present embodiment, using common xanthochromia glue, mixing time 45S, after stirring
Standing setting time is 25min, and selecting partial size is the rubble of 3mm-5mm, and water permeability is stronger, while convenient for metaling and poly- ammonia
The mixing of ester gum stick and paving for mixture, within the dosage control 15kg of each polyurethane adhesive, with being accurate to
The electronics Libra of 0.01g weighs, and when mixing first pours into load weighted B component in the container of dried and clean, then by suitable A group
It is sufficiently stirred after pouring in separately container with stirring electric drill；Forbid not carrying out ingredient to scale.
S2, the metaling and polyurethane adhesive that prepare in step S1 are matched, stirred, preparing mixture；Gluing
Agent dosage accounts for the 2.8% of metaling quality, and using mechanical stirring, mixing time 3min, to guarantee construction quality, scene is set specially
People is responsible for material proportion weighing, and the weight error of polyurethane adhesive controls in 1%, and the weight error control of metaling exists
In 2%, the dosage of adhesive is matched according to rubble specific gravity and functional performance attribute in mixture, when pavement construction more
