Description
Technical field
The present invention relates to geotechnical process field, specially a kind of polypropylene high-strength geotextile and its applying for road surface is applied to
Work method.
Background technology
China's geosynthetics is in the case where the policy of reform and opening-up promotes, though product has certain basis and scale, low water
Flat polyisomenism is serious, and product development and home and abroad market survey are thinked little of, and it is greatly poor to exist compared with the country of prosperity
Away from the not perfectly flat weighing apparatus of development of every field, some designs and the relevant specification constructed are not kept pace with coming.Research institutions' also not yet shape
Into the complete subject group of raw material, the manufacturing, detection and construction application.
At the same time, selection of the domestic geosynthetics industry to raw material is smudgy, particularly to terylene and third
Synthetic fibre chemical characteristic understanding deficiency.The dacron product that facile hydrolysis generates salt and gradually failed in the basic conditions is widely used in alkali
In property environment, chemical metallurgy antiseepage, or some other environment directly contacted with alkaline matters such as cement and limes.Polypropylene fibre is immersed in
In PH=12.3 calcium chloride solution, intensity does not almost reduce；And polyester fiber be immersed in PH=12.3 calcium chloride+
In 0.03%FeSO4 solution, intensity decreases 25%, therefore, reply are any limitation as with the material that engineering material directly contacts, and are
This, it is proposed that a kind of polypropylene high-strength geotextile suitable for extremely frigid zones.
The content of the invention
It is an object of the invention to provide a kind of polypropylene high-strength geotextile, is asked with solve to propose in above-mentioned background technology
Topic.

Preferably, waterproof anticracking base fabric is applied on road surface, including roadbed, and it is steady that the upper end of the roadbed is equipped with subgrade drainage
Layer, the upper end of the roadbed steady layer of water are equipped with waterproof anticracking base fabric, and the upper end of the waterproof anticracking base fabric is completely covered with asphalt road
Surface layer, the permeable groove is interior to be filled with coal tar, and the lower end of coal tar is connected with roadbed steady layer of water.
Preferably, the roadbed steady layer of water is mixed by cement, flyash and rubble, and the weight ratio of cement account for it is total
Than 4%-8%, the weight ratio of flyash is accounted for always than 9%-15%, rubble polishing.
The construction method that a kind of polypropylene high-strength geotextile is applied to road surface comprises the following steps：
S1, with rammer compacter road surface is tamped；
S2, rubble is uniformly layered on roadbed, is uniformly added into flyash, finally upper cement, carried out levelling；
S3, waterproof anticracking base fabric is layered in not dry roadbed steady layer of water, after after roadbed steady layer of water parches, permeable recessed
The full coal tar of filling in groove；
S4, the waterproof anticracking base fabric completed upper end spray 1.0-1.2Kg/m2Blacktop (4)；
S5, before the uncolled solidification of blacktop, one layer of uniform particle sizes thickness 0.8-1.2cm of spread, and clean dustless
Load-bearing grain stone；
S6, load-bearing grain stone form hard surface through rolling to be embedded into blacktop.
Preferably, the thickness of the blacktop is between 3-5cm, the thickness of waterproof anticracking base fabric 1-1.5cm it
Between.
Preferably, the load-bearing grain stone uses basalt or granite grain stone.
Preferably, the blacktop maintains the temperature at 120 DEG C -140 DEG C during sprinkling.
Compared with prior art, the beneficial effects of the invention are as follows：Polypropylene high-strength geotextile of the present invention is especially
Suitable for extremely frigid zones, waterproof anticracking base fabric forms pitch complex waterproof layer with coal tar, because pitch complex waterproof layer is with height
The polypropylene fibre base fabric of intensity is carrier, and pitch penetrates into all fine spatials of fiber, and waterproof effect is extremely stable, and this is multiple
The drain function that waterproof layer is also equipped with horizontal direction is closed, underground water is after upwardly direction is obstructed by pitch complex waterproof layer, meeting
Discharged from horizontal both sides, reduce the water pressure inside road structure, important function is served to integrally-built stabilization, passed through
To roadbed steady layer of water gather materials for sand, rubble, cement and gather materials for flyash, rubble, cement two kinds of proportioning tests, as a result send out
Not only its workability is preferable for the cement stabilizing compound of existing adding coal ash, and test block is easily molded, and the present invention has structure
Simply, good water-proof effect, the features such as suitable for extremely frigid zones.
