Embodiment Construction

[0009] The present invention will be further described below in conjunction with specific embodiment:

[0010] A road asphalt, in terms of weight percent, is composed of the following components: 100 parts of asphalt, 4 parts of styrene-butadiene rubber, 3 parts of neoprene rubber, 3 parts of isoprene rubber, 5 parts of polystyrene, N-isopropyl- 1 part of N-phenyl-p-phenylenediamine, 2 parts of dimethyl phthalate, 0.5 part of p-tolualdehyde, 4 parts of mica powder, 4 parts of sodium alkylbenzene sulfonate, 6 parts of polyvinyl alcohol, 2 parts of caustic soda. Among them, polystyrene has good mechanical properties as the modified resin, mica powder is used as the modification auxiliary agent, and the functional auxiliary agent is selected from isoprene rubber.

[0011] Compared with the existing road asphalt, the road asphalt is much better than the existing products in all indicators. After testing, it is found that the splitting strength of the present invention can reach 3...

Abstract

The invention discloses road asphalt. The road asphalt is prepared from the following components by weight percentage: 80-100 parts of asphalt, 3-15 parts of styrene butadiene rubber, 2-5 parts of neoprene, 2-5 parts of isoprene rubber, 2-6 parts of polystyrene, 0.3-3 parts of N-isopropyl-N-phenyl-p-phenylenediamine, 0.5-5 parts of dimethyl phthalate, 0.1-1 part of p-tolualdehyde, 3-10 parts of mica powder, 1-7 parts of sodium alkyl benzene sulfonate, 3-8 parts of polyvinyl alcohol and 1-3 parts of caustic soda. The road asphalt has a good interlayer bonding degree, the high-temperature stability performance of the asphalt can be effectively improved, and meanwhile, the brittleness temperature is decreased so that the low-temperature anti-cracking performance of the asphalt can be improved; the asphalt is high in viscosity, resistant to high temperature and good in waterproof property, and has high ability of resisting high-temperature and rainy weather, and thus, the damage rate of roads is greatly decreased.

Description

Technical field: [0001] The invention relates to an asphalt, in particular to a road asphalt. Background technique: [0002] With the rapid development of highway construction in our country, while the mileage of highways has increased rapidly year by year, the traffic flow and heavy-duty vehicles on the highways have increased rapidly, and the wear and tear of the road surfaces has greatly increased compared with before. It has become urgent to improve the quality of the road surface and prolong the service life of the highway. Especially in summer or in some areas prone to high temperature and rainy weather, the viscosity of the road surface will be greatly reduced, and the passage of traffic will easily damage the road. With the large-scale, heavy-duty, and overloading of vehicles in my country's road transportation, the requirements for high-temperature stability, low-temperature crack resistance, aging resistance, and durability of modern roads are getting higher and hi...
