As a modification of the present invention, described step (3) specifically includes following steps:
(3.1) asphalt is heated to 170～190 DEG C, stirs when adding mixture, the speed setting of agitator is extremely
Few 900 revs/min, continue heated and stirred,；
(3.2) continue 170～190 DEG C of keeping temperature, to be mixed develop 20～60 minutes after, subsequent natural cooling, work as temperature
Degree is reduced to 100～120 DEG C, makes to obtain Oleum Gossypii semen low-viscosity rubber asphalt product.
A kind of implement above-mentioned utilization Oleum Gossypii semen and produce the product that low-viscosity rubber asphalt method is obtained, its each component and weight
Amount percentage ratio is as follows:
Asphalt 50～60%,
Waste-tyre rubber-powder 10～20%,
Oleum Gossypii semen 20～30%.
A kind of above-mentioned utilization Oleum Gossypii semen produces the prepared product of low-viscosity rubber asphalt method come making Lamina,
Oleum Gossypii semen low-viscosity rubber asphalt product is mixed with having the mineral aggregate phase that a deciding grade and level joins, obtains asphalt, wherein Colophonium
Compound mix drop temperature is 95～105 DEG C, forms Lamina after bituminous mixture laying is rolled.
As a modification of the present invention, the thickness of described Lamina is 1～2.5cm.
The invention has the benefit that the technique of the method for present invention offer is simple, it is easy to accomplish, extremely low using contaminative
And the Oleum Gossypii semen of relative low price, by optimization of C/C composites and adopt science preparation technology, can prepare have good application property,
Workability and oligosaprobic Oleum Gossypii semen low-viscosity rubber asphalt product, simultaneously take account of its low temperature performance well, anti-cracking ability by force,
But the weaker feature of high-temperature behavior, uses it for making Lamina in bituminous pavement preventive maintenance, the thickness after decking and rolling
Degree controls between 1～2.5cm, can use as ultra-thin wearing layer during bituminous pavement preventive maintenance, has low cost, apply
Work workability is good, and the advantages of smoke dust pollution, free from extraneous odour, the road surface low temperature anti-cracking ability of making is strong, and good endurance is comprehensive
Can be good, thus saving petroleum resources, environmental protection, reduces cost, beneficial to wide popularization and application simultaneously.
With reference to embodiment, the invention will be further described.
