Description
Technical field
The present invention relates to a kind of pitch, especially a kind of anti-rutting asphalt.
Background technique
Bituminous pavement under local function caused by track, push away gather around, wave, gather around packet etc. diseases the road of bituminous pavement is used
Performance declines rapidly, and these problems are primarily generated on runway, when vehicle in the process of moving, be moved slightly away from direction of traffic
When left and right vehicle wheel will be caused to shake, bring the uncomfortable feeling of passenger.When track reaches certain depth, it is sufficient in wheelmark
Band internal water accumulation, will lead to Water Damage on Asphalt Pavement, while the vehicle of fast running thereon being made to be easy to produce water drift.For cold
Cold season section, ponding freeze, and the antiskid performance on road surface will substantially reduce, and influence traffic safety.And traditional glass asphalt mixing
Material is easily crushed since there are cullet in gathering materials, and stability is lower, and road surface is easy to appear the diseases such as track and cracking, and
Since the presence of cullet will affect construction safety, construction personnel is easy to be scratched by cullet at work.
Summary of the invention
The object of the present invention is to provide a kind of anti-rutting asphalt, the pitch is at low cost, density is big, intensity is high, Rut resistance effect
Fruit is good, while can be improved the antistrip performance and reflective function of asphalt, has good intensity, stability and resistance to
Long property.
To achieve the above object, the technical scheme is that a kind of anti-rutting asphalt, includes 8-15 parts by weight ratio
The low grade hard grades of bitumen of needle penetration 15-35dmm, 20-30 parts of miberal powder, 20-30 parts of rubble, 5-10 parts porous anti-
Light glass microsphere, 0.5-1.5 parts of fiber stabilizer, 50-68 parts of aggregate, 0.5-1 parts of antistripping agent, 1-8 parts of modifications
Agent, the modifying agent are the mixture of chlorinated polyethylene rubber and thermoplastic elastomer (TPE), and the weight part ratio of the two is 2-6:3-5,
Wherein low grade hard grades of bitumen includes 45-65 parts of bitumen mother liquors, 2-4 parts of chlorinated polyethylene rubbers and 35-55 parts of petroleum drips
Blueness is constituted；
Further, the miberal powder is the mixture of basalt powder and niter powder.
Further, the antistripping agent is LOF65-00 amides antistripping agent.
Further, the partial size of the perforated retroreflective glass microballoon is 2.5~4mm, and aperture is 30-60 μm, refractive index is 2~
2.5；
The gradation of the rubble meets: by sieve pore be 19mm, 13.2mm, 9.5mm, 4.75mm, 1.18mm, 0.5mm,
When the screening of 0.3mm, 0.15mm, 0.05mm sieve, the ratio of the gradation of the rubble be 100:91~88:60~78:50~
59:25~45:22~30:12~25:8~18:8~12:6.
The beneficial effects of the present invention are: the pitch is at low cost, density is big, intensity is high, Rut resistance effect is good, without additional
Anti-rutting additive etc. only needs simple asphalt material mix construction, can effectively prevent to push away and gather around, wave, gather around asking for packet
Topic, while can be improved the antistrip performance and reflective function of asphalt, have good intensity, stability and durable
Property.
