Abstract
The present invention discloses one kind of asphalt modifier, which is prepared with anthracene oil and tanning extract in the weight ratio of 1-3, and through smelting and mixing at 40-80 deg.c, naturally cooling and packing. The asphalt modifier may be used for modifying new asphalt material and waste asphalt material for reuse. The present invention makes it possible to reuse waste asphalt so as to reach the aims of protecting environment and saving cost.
Description
Technical field
The present invention relates to a kind of properties-correcting agent, relate in particular to a kind of asphalt modifier.
Background technology
The drop table label that the frigid zone highway uses should be higher, softening temperature should be less than normal, ductility should increase; The pitch label that torrid zone highway uses is suitable on the low side, ductility can be slightly less than normal in normal value, and penetration degree is suitable less than normal, and softening temperature is suitable higher.In the real work, often the bituminous buying is because of many reasons such as cost, transport power, keepings, so buying pitch quantity is bigger, the pitch that generally can not purchase various labels is standby.But need adopt the pitch of different labels when using by climate.This has just caused the inconvenience of using.Simultaneously highway reconstruction, overhaul, in repair and routine maintenance work in, regular meeting takes a large amount of waste asphalt pavement materials and discards or landfill.Depleted old asphalt pavement material has plenty of use for many years, and change has taken place necessarily to take off the bituminous material pavement performance; Have plenty of on business the road and reconstruct the section of one-tenth discarded and working life of not oversize original highway section, the bituminous material pavement performance takes off and becomes little.In a word, no matter be to take to dig to abandon or landfill, all will cause the environmental pollution and the pitch wasting of resources, also can increase engineering cost.
Summary of the invention
The object of the present invention is to provide a kind of new asphalt modification of low grade that can make is the new pitch of high grade, reaches and can satisfy the service requirements of different climate bituminous pavements to the different pitches label, the asphalt modifier that the waste asphalt modification is utilized again again.
Asphalt modifier of the present invention, its raw material weight proportioning is as follows:
Carbolineum: tannin extract=1:1～3:1.
The production method of a kind of asphalt modifier of the present invention, with above-mentioned materials of weight proportions, hot melt is even under 40～80 ℃ of conditions mixes, naturally cooling, packing promptly gets asphalt modifier of the present invention.
The present invention compares with existing asphalt modifier has tangible advantage and effect, and the present invention both can carry out modification to new pitch.Can carry out modification to the waste asphalt that reclaims again, its penetration degree, ductility and softening temperature three big indexs be changed meeting the road bitumen technical requirements, thereby recover the waste asphalt mixture pavement performance, reach old material recycling purpose.Both saved cost, having reduced in a large number again cuts into a mountain gets stone and the long-pending land occupation of waste, and it is very remarkable to be beneficial to environmental protection economic benefit of the present invention, cost-saved more than 30%; Construction technology of the present invention is simple, is easy to promote and steady quality.
Embodiment
Below example further specifies beneficial effect of the present invention by experiment:
Below be the test-results that embodiment 3 gained asphalt modifiers add waste asphalt, see the following form:
Below be that embodiment 3 gained asphalt modifiers add new bituminous test-results, see the following form:
Embodiment 1:
With tannin extract 90kg, carbolineum 90kg, hot melt is even under 40～80 ℃ of conditions mixes, naturally cooling, packing promptly gets asphalt modifier of the present invention.
Embodiment 2:
With tannin extract 30kg, carbolineum 60kg, hot melt is even under 40～80 ℃ of conditions mixes, naturally cooling, packing promptly gets asphalt modifier of the present invention.
Embodiment 3:
With tannin extract 30kg, carbolineum 90kg, hot melt is even under 40～80 ℃ of conditions mixes, naturally cooling, packing promptly gets asphalt modifier of the present invention.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, any technical solution of the present invention content that do not break away from,, all still belong in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present invention.
