The environmental protection item discard foetus gum powder to change sex asphalt foreground vast

Road political situation in Peking City managed to convene "discard foetus gum powder to change sex asphalt application study" an expert a reviewing meeting in Peking and attended meeting an expert formation consistent of reviewing opinion.The expert think that the topic set is according to the research outline, rightness domestic and international discard foetus gum powder in the road engineering of application open an exhibition thorough of investigation and analysis, carry on a rubber asphalt and mixture anticipate of main function experiment, obtained a stage research result.
Attend meeting an expert to also think, the topic set of this item is in the investigation, summary domestic and international research result of foundation up, put forward of research contents reasonable, want the key technique for solve explicit, technique route and implement project can line.
The road bridge road in Peking interest supplies center held the post of "discard foetus gum powder to change sex asphalt application study"'s technique of the item to offend pass mission, according to should center president Gao Jun4 introduction, this item be a research item of transportation committee in Peking City 2004, from Peking City road political situation, road bridge road in Peking interest supplies center and the science graduate school cooperation of the Ministry of Transportation & Communications highway research.Should item research of the main purpose pass to experiment research, establishment rubber asphalt and rubber asphalt mixture anticipate of technique index sign and standard, combine weather condition, transportation condition and material characteristics of Peking City on this foundation, establishment rubber asphalt in Peking and mixture anticipate a design construction technique guidebook.
Should center general manager, Liu2 Zhen4, tell a reporter, the rubber powder change sex asphalt to used for road noodles in can show Zhao improvement heavy carry the anti- car Zhe, anti- of road noodles to transform with anti- tired ability, reduce thin road noodles thickness, defer glint crack combine the extension road noodles service life, can be significant to lower line car noise in the meantime, is typical model of green environmental protection item.Discard foetus gum powder in the asphalt the mixture anticipate of application can digest a great deal of of the car discard a foetus and ease a tire processing to bring thus of society and environment pressure.Should center total the detailed introduction, now of engineer, Liu3 Hao4, , our country every year of abandon a tire to have 187,000,000 around, take 2003 as an example, put off to abandon tire about 100,000,000, light Peking have 720 have another 10000.So, the whole country processing abandon the pressure of tire very big, if availably expansion discard foetus gum powder to change a sex asphalt technique, that will availably alleviate this kind of pressure.For discard foetus gum powder to change the function of sex asphalt, Liu3 Hao4 introduction, discard foetus gum powder to change the application study of sex asphalt, have already had the history for more than 30 years abroad, from the federal highway in the United States bureau of experiment the data see, the function which discard foetus gum powder to change sex asphalt very superior.While carrying on acceleration to add to carry fatigue test 100,000 times, common asphalt road the noodles appear to open crack etc. the disease harm, but discard foetus gum powder to change sex asphalt intact have no Sun, arrive 300,000 times, discard foetus gum powder to change sex asphalt road noodles still keep having never appeared a disease to harm, but common asphalt road noodles already damaged get fierce.Speak of a problem of decline the Zao, Liu3 Hao4 introduction, the usage discard foetus gum powder to change the road noodles of sex asphalt, can lower noise 2-3 decibels, this equal to car discharge decrease 40%, the building keep off highway 100%.While speak of economy index sign, Liu3 Hao4 tell a reporter, discard foetus gum powder to change sex asphalt price to change sex asphalt cheapness 20% than the SBS or so.Liu3 Hao4 Shuo, discard foetus gum powder to change sex asphalt to have a very strong environmental protection function, function superior, can lower noise, sex price ratio Gao, have extremely vast of development application space.2004, road bridge road in Peking interest supplies center already in Peking agreeable the righteousness area spread to build experiment road segment, up to currently, experiment the effect be equal ideal.
Liu3 Hao4 further introduction say, "discard foetus gum powder to change sex asphalt application study" through a year of experiment research with experiment the segment spread to build, already get first step conclusion, at present stage experiment research of foundation up, the topic set be thin to turn next move work plan, at thorough research rubber asphalt and it mixture anticipate of the foundation of mechanism and function up, further spread to build experiment road segment, argument rubber asphalt mixture anticipate to decline Zao etc. function, further perfect research result, at this foundation top establishment feat, the credibility, viable rubber asphalt in Peking and mixture anticipate design construction technique guidebook, for it application provide a technique basis.
