Description
Technical field
The invention belongs to bituminous pavement preventive maintenance material field, particularly relate to a kind of rubber asphalt ultra-thin wearing layer and mix
Close material and there is the rubber asphalt ultra-thin wearing layer of noise reduction antiskid.
Background technology
Along with national economy and the development of communication, people are to the requirement of asphalt highway service level increasingly
High.Highway traffic noise has become as a main source of pollution from environmental noise, and the control problem about traffic noise is got over
More cause the attention of people.In China large-and-medium size cities, the particularly ground automobile pollution such as Beijing, Shanghai, Guangzhou increases year by year
Add, therefore create sound pollution and vehicle accident, the metropolis persistent ailment such as block up.Health of people problem is produced tight by traffic noise
Ghost image rings, and can affect the nervous system of people, produces the phenomenons such as irritability, irritability, impact sleep.Therefore, in China, the China people are altogether
In " the improving the instruction of town and country sound environment quality about strengthening noise pollution prevention work " issued with Chinese Ministry of Environmental Protection of state
Emphasize to strengthen traffic noise pollution preventing and treating.
Although China uses a lot of methods in terms of traffic noise reduction, as noise reduction afforests forest belt, sound barrier technology, green wall technology
Deng, reduce a part of noise to a great extent, but these measures bring environment unsightly, resident is made troubles etc. and to ask
Topic.Above several method is all traditional method reducing noise.Above-described noise reduction measure, seldom from pavement of road angle
Set off in search solution.For small and medium-sized car, along with the raising of running velocity, tyre noise is in the noise that automobile produces
Ratio increasing, directly build Low Noise Pavement and seem more meaningful.
In recent years, have absorb traffic noise, the ground surface material that improves pavement skid resistance function becomes the focus of research.Therefore
The teaching of life, rest environment and the school along the line of subjective reflection is disturbed by traffic noise big for flow, the high generation of speed
And the rainy day increases the most serious problems such as traffic safety, research and develop a kind of Colophonium having and reducing noise with strengthen security function
Ground surface material, is allowed to have good reduction traffic noise and raising antiskid performance effects, and can strengthen road safety performance
Ground surface material, road improvement road-ability.
In recent years China's rubber asphalt ultra-thin wearing layer prepare raw material mainly have rubber asphalt AC ultra-thin wearing layer compound,
Rubber asphalt SMA ultra-thin wearing layer compound, and open gradation OGFC asphalt.Wherein, rubber asphalt AC ultra-thin wearing layer
Rubber asphalt AC ultra-thin wearing layer prepared by compound is little due to its voidage, does not seeps water in road surface；And superficial makings is less,
Pavement friction is the least, and therefore, its noise reduction is not ideal enough, antiskid poor performance.Rubber asphalt SMA ultra-thin wearing layer compound system
Standby rubber asphalt SMA ultra-thin wearing layer has preferable superficial makings structure, but owing to voidage is less, is unfavorable for reducing
Noise, noise reduction is poor, and does not seeps water in road surface；And join compound due to it to need to fill certain fiber so that it is
Cost increases.Open gradation OGFC Air Voids of Asphalt Mixtures is maximum, but just because of its voidage is big, early stage acoustically effective
Ideal, pavement usage time length, dust foreign material easily block space, and later stage noise reduction is bad, thus adds
Maintenance cost；It addition, its water stability, durability are worst.The noise reduction capability of above-mentioned rubber asphalt ultra-thin wearing layer is the most poor.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of rubber asphalt ultra-thin wearing layer compound and there is noise reduction resist
Sliding rubber asphalt ultra-thin wearing layer, rubber asphalt prepared by the rubber asphalt ultra-thin wearing layer compound that the present invention provides is ultra-thin
