Abstract
The invention relates to an asphalt road surface material which is applicable to crossroads and bus station platforms in severe cold regions, aiming to solve the problem that the asphalt road surfaces on the bus station platforms which buses drive into frequently and on the side of stop line at crossroads with larger traffic flows in large cities in northern severe cold regions are rugged due to frequent braking. In the invention, the mass of rubber modified asphalt accounts for 9.6-10.3% of the total mass of aggregate and filler, the mass of iron ore tailing sands accounts for 2.8-4.2% of the total aggregate mass, the grain diameters of basalt are 5-8mm and 14-17mm. The inventive asphalt road surface material can not have upheavals or tracks in summer even under the condition of frequent braking, or crack in winter, thus being especially suitable for frequent braking positions at bus station platforms, crossroads with larger traffic flows, slope base of descending sections in cities in severe cold regions.
Description
Technical field:
The present invention relates to a kind of asphalt pavement material.
Background technology:
In the city of northern extremely frigid zones, often can see a kind of like this road conditions, frequent platform of stopping of full-sized bus and the intersection that has signal lamp to control, owing to excessive reason of motorbus deadweight and the kinetic energy factor that produced when frequent starting and braking in above-mentioned highway section, tend to road pavement and cause quite serious destruction, road crust damages and produces to disclose and wraps and groove.Make that this place's bituminous pavement is uneven, vehicle walks to herein all can produce severe turbulence, has influenced the stability of driving, when especially bus enters platform just the passenger disseat and prepare to get off, cause to run foul of each other and trample because vehicle jolts and makes passenger's astasia this moment.Even the new bituminous pavement of laying after through the use in 1 year, also can produce above-mentioned situation.The destructive road surface has also influenced the image in city to a certain extent, traces it to its cause, and be to fail to consider above-mentioned factor in the design on this road surface, and design and construction is with normally the road surface is identical.The way of dealing with problems is the pavement material that improves this highway section, increases road surface elasticity and intensity, with the destruction of avoiding this highway section to be caused.
The temperature difference in the bituminous pavement 1 year of north extremely frigid zones is more than 70 ℃, and the pavement temperature in winter is lower than subzero 30 ℃, and the pavement temperature in summer (under the sunlight) is higher than 40 ℃ above freezing.The design department of road should consider that the anti-low-temperature cracking problem of bituminous pavement considers the high-temperature softening deformation problem on road surface again, the road surface temperature difference greater than 70 ℃ situation under, the high low temperature problem of taking into account bituminous pavement is more thorny really.
Summary of the invention:
The objective of the invention is the public transport platform and the bigger intersection of vehicle flowrate of frequently sailing into for the big or middle city bus that solves northern extremely frigid zones, because frequently braking and starting make that this place's bituminous pavement is uneven, vehicle walks to all can produce herein and jolts, influence vehicle and exercise the problem of stability, a kind of asphalt pavement material that is applicable to extremely frigid zones city intersection and public transport platform is provided.
The object of the present invention is achieved like this: asphalt pavement material of the present invention is by rubber modified asphalt, gather materials and filler make, the quality of described rubber modified asphalt is to gather materials and 9.6～10.3% of filler total mass, described rubber modified asphalt is made by petroleum pitch and waste and used rubber tyre powder, the quality of described waste and used rubber tyre powder is 18～21% of an oil pitch quality, the granularity of described waste and used rubber tyre powder is divided into two kinds in 10 orders and 30 orders, wherein 10 purpose waste and used rubber tyre powder account for 45～65% of all waste and used rubber tyre powder total masses, 30 purpose waste and used rubber tyre powder account for 35～55% of all waste and used rubber tyre powder total masses, described filler is a prepared from tailing sand of iron ore, the quality of described prepared from tailing sand of iron ore is 2.8～4.2% of the total mass of gathering materials, described gathering materials is the basalt building stones, the particle diameter of described basalt building stones is divided into 5～8mm and 14～17mm two kinds, wherein the basalt building stones of 5～8mm particle diameter account for 50～75% of the total mass of gathering materials, and the basalt building stones of 14～17mm particle diameter account for 25～50% of the total mass of gathering materials.The making method of asphalt pavement material of the present invention is: described petroleum pitch is dissolved the waste and used rubber tyre powder that the back adds two kinds of specifications, under 180 degrees celsius, mix and stirred 1～1.5 hour, be incubated 30～60 minutes then and make rubber modified asphalt, add when the temperature of rubber modified asphalt is reduced to 150 degrees centigrade and gather materials and filler stirs and gets final product.The laying of asphalt pavement material of the present invention should meet the requirement of " asphalt highway construction technique normalizing " (JTG F40-2004).
The invention has the beneficial effects as follows:, high temperature resistant, antifatigue, cracking resistance seam, advantage such as anti-aging are arranged by the rubber modified asphalt of macrobead waste and used rubber tyre powder preparation and the asphalt pavement material that is mixed with the prepared from tailing sand of iron ore preparation.Even promptly gather around bag, rut at the high temperature season frequently braking in summer with starting to walk can not produce, road pavement can not damage yet yet, and can not produce the crack cold season in winter yet.The work-ing life of this asphalt pavement material is higher more than 30 one 50% than plain asphalt ground surface material, is particularly suitable for extremely frigid zones city bus platform, intersection, descending highway section that vehicle flowrate is bigger are laid near frequent brakes place such as the ends, slope and used.Even above-mentioned highway section traffic flow is big, also can guarantee the work-ing life in 10 years.In addition, this bituminous pavement adds rubber powder and has the noise that produces when certain elasticity can reduce car brakeing, low about 4～6 decibels of the noise of other bituminous pavement of noise ratio of this bituminous pavement, and sensation can be more comfortable when travelling on such highway section.In addition, the present invention has utilized prepared from tailing sand of iron ore, and CHARACTERISTICS OF TAILINGS SAND belongs to utilization of waste material, can reduce unnecessary occupation of land and to the pollution of environment.
