Description

A kind of Asphalt Pavement Damage repair cold-repairing material and preparation method thereof
Technical field
The invention belongs to asphalt preparation field, it is related to a kind of Asphalt Pavement Damage repair cold-repairing material and its preparation Method.
Background technology
Bituminous paving has preferable mechanical strength, adapts to various drivings as a kind of jointless continuous pavement Load, and have many advantages, such as driving steady, comfortable, low noise and easy to repair, it is more and more widely used.Asphalt road Face is during long-term use, it may appear that the diseases such as pit slot, loose, peeling influence road normal use, or even cause traffic Accident.The diseases such as pit slot, the breakage therefore occurred for road surface need to be repaired in time.Road surface pit repairing vulcanizes method and cold Place is concentrated in 2 type of reinforcing method, traditional hot patching construction, and the larger pavement maintenance of quantities is feasible, but for Place disperses, and the small pavement maintenance of quantities is inconvenient, and cannot normal construction in rain and snow.Cold-patch method compensates for The deficiency of method is vulcanized, can also be constructed in rain and snow, it is easy to operate, while can be energy saving, reduce environmental pollution.
In the 1990s, external cold asphalt mixture initially enters China, to drive research and development of the China to cold-repairing material.Through The effort of recent two decades is crossed, occurs the cold-repairing material of many domestic independent brands in succession.But the cold-repairing material quality of domestic production is good Green bristlegrass is uneven, and cold-repairing material is low temperature resistant and high temperature resistance is poor, and the brittle crust of low temperature environment, hot environment easily softens, and causes road Surface evenness is deteriorated, and often initial strength is not high for cold-repairing material, causes performance poor, is easy loosely to fall off so that cold-patch Material often can only be as the interim handle measure of disease.
Invention content
In view of this, the purpose of the present invention is to provide a kind of Asphalt Pavement Damage repair cold-repairing material and its preparation sides Method.
In order to achieve the above objectives, the present invention provides the following technical solutions:
1. a kind of Asphalt Pavement Damage repair cold-repairing material, including gather materials, pitch and cold-patch agent, it is described to gather materials including rubble And Machine-made Sand, ballast grain sizes 5mm-16mm, bitumen aggregate ratio 4-6%, the cold-patch agent account for cold-repairing material gross mass 1.0~ 1.5%.
Further, bitumen aggregate ratio 5%.
Further, the cold-patch agent is made of following mass fraction formula components:Terpene resin 30-34%, epoxy resin 2-4%, heavy oil 16-18%, diesel oil 44-52%.
Further, the Machine-made Sand is limestone;The pitch is matrix pitch or SBS modified pitch.
Further, described to gather materials in mass ratio for 10-15mm:5-10mm:0-5mm=10-12%:45-47%:42- 44%.
Further, described to gather materials in mass ratio for 10-15mm:5-10mm:0-5mm=11%:46%:43%.
Further, the grading limit gathered materials is:Gathered materials 13.2mm sieve pores percent of pass be 100%, cross 9.5mm sieve Hole percent of pass is 70%-100%, and it is 40%-70% to cross 4.75mm sieve pore percent of pass, and it is 18%- to cross 2.36mm sieve pore percent of pass 38%, it is 8%-20% to cross 1.18mm sieve pore percent of pass, and it is 4%-15% to cross 0.6mm sieve pore percent of pass, crosses 0.3mm sieve pores and passes through Rate is 3%-12%, and it is 2%-9% to cross 0.15mm sieve pore percent of pass, and it is 1%-7% to cross 0.075mm sieve pore percent of pass.
Further, rubble and Machine-made Sand are mixed and stirred according to determining ratio, it is 120~130 DEG C to mix and stir temperature, then sprays drip Blueness after 5~10 seconds, sprays miberal powder uniform mixing, at least 50 seconds mixing time, adds pitch cold-patch agent, stir, It paves and waits drying in the air to room temperature.
Further, asphalt temperature is 120-130 DEG C.
Further, after the agent of pitch cold-patch is added, mixing time is 5~10 seconds.
The beneficial effects of the present invention are:The present invention provides a kind of pitch cold-repairing materials to overcome traditional asphalt cold repairing mixing Material is easily hardened, durability is poor and workability is poor, and with repairing at any time, workability is good, temperature stability is good, and shaping strength is high, water The features such as excellent in stability, durability is good, easy to store, effectively extends cold-repairing material service life, has broad application prospects.It is cold Terpene resin, epoxy resin can form complicated colloform texture again in the cold-patch agent added in feed supplement between aggregate and pitch, It can significantly improve the wetness degree of aggregate, improve the bonding force of aggregate and pitch, heavy oil, the diesel oil of rational proportion improve cold The low temperature fluidity of feed supplement.The cold-patch agent significantly improves asphalt softening point, needle penetration and rutting resistance and improves Resist low-temperature bending damage capability.
