Abstract
The invention discloses a rubber pitch, which comprises the following components according to weight portion: 100 portions of pitch, 25 to 35 portions of rubber, and 10 to 20 portions of modifier. The modified pitch of the invention can effectively improve the property of pitch, is suitable for roadway paving and has long service life.
Description
Technical field
The present invention relates to a kind of rubber asphalt.
Background technology
Bituminous pavement generally is made up of with gathering materials pitch.The use on oxidation, weather condition and the road surface of bituminous cement between its usage period is particularly used through heavy load, has caused the road surface to be degenerated along with the past of time.For example, the road surface is shunk repeatedly owing to temperature variation and has been caused the road surface to form vertical crackle during the night in winter of cold, is called as cold fracture.Bituminous cement becomes too soft during the summer of sweltering heat, caused road surface tension set under heavy loading repeatedly, is called " rut ".In addition, it is tired that the result of successive mechanical stress is that the road surface becomes, and caused forming the crackle as crocodile skin, is called as repeated stress failure.
But the bituminous wax content is higher, and the road surface of causing asphalt paving is easily softening when high temperature, produce pile-up, permeable, form phenomenons such as reflection crack, surface deformation, a large amount of maintenance of surface expenses is had to drop in the havoc road surface therefore.Proposed multiple in the prior art to the pitch method of modification in addition.Chinese patent application 90104833.X (publication number is CN1058412A) has disclosed a kind of modifying asphalt that machinery is extruded the clad metal pipeline that is used for, and its main component is byerlyte, Atactic Polypropelene, short glass fiber, regenerated rubber, talcum powder and linking agent etc.Make miscible crosslinked this modifying asphalt that obtains of above-mentioned substance by physics, chemical process.Do not provide the performance of this modifying asphalt in the document.The softening temperature of modifying asphalt of the prior art still remains to be improved, to satisfy the needs of pavement asphalt better.
Summary of the invention
The objective of the invention is provides a kind of rubber asphalt in order to solve shortcoming of the prior art.
For realizing above purpose, the present invention is achieved through the following technical solutions:
A kind of rubber asphalt is characterized in that, is made of pitch 100 weight parts by weight following component; Rubber 25-35 weight part, properties-correcting agent 10-20 weight part.
Wherein, described properties-correcting agent is the residue of gelatin liquefaction.
Wherein, described properties-correcting agent is made up of toluene and tetrahydrofuran (THF).
Modifying asphalt among the present invention can effectively improve the bituminous performance, is fit to the laying road road surface, long service life.
Embodiment
The present invention will be further described below in conjunction with specific embodiment:
Embodiment 1, and a kind of rubber asphalt is made of by weight following component, pitch 100 weight parts; Rubber 25 weight parts, residue 10 weight parts of gelatin liquefaction in the residue of gelatin liquefaction, are made up of the toluene and 65% tetrahydrofuran (THF) of weight percent 35%.
Pitch is added in the stirred pot, add rubber powder down, fully mix, leave standstill, when temperature is reduced to 150 ℃, add coal liquefaction residue, continue to stir, be warmed up to 220 ℃ and continue to stir 1 hour at 220 ℃.
Embodiment 2, and a kind of rubber asphalt is made of by weight following component, pitch 100 weight parts; Rubber 30 weight parts, residue 15 weight parts of gelatin liquefaction in the residue of gelatin liquefaction, are made up of the toluene and 75% tetrahydrofuran (THF) of weight percent 25%.
Production method is identical with embodiment 1.
Embodiment 3, and a kind of rubber asphalt is made of by weight following component, pitch 100 weight parts; Rubber 35 weight parts, residue 20 weight parts of gelatin liquefaction in the residue of gelatin liquefaction, are made up of the toluene and 60% tetrahydrofuran (THF) of weight percent 40%.
Production method is identical with embodiment 1.
Embodiment 4, and a kind of rubber asphalt is made of by weight following component, pitch 100 weight parts; Rubber 35 weight parts, residue 10 weight parts of gelatin liquefaction in the residue of gelatin liquefaction, are made up of the toluene and 80% tetrahydrofuran (THF) of weight percent 20%.
Production method is identical with embodiment 1.
The foregoing description only is used for that the present invention will be described, does not constitute the restriction to the claim scope, and other alternative means that it may occur to persons skilled in the art that are all in claim scope of the present invention.
