Abstract
The rut resisting admixture for high-grade asphalt highway consists of low density polyethylene of 20-50 kD 50-85 weight portions, high density polyethylene of 10-30 kD 10-45 weight portions, petroleum asphalt in 10-50 needle penetration 5-10 weight portions and diatomite 5-20 weight portions. Experiment shows that the rut resisting admixture of the present invention has low material consumption, low production cost, good waterproof performance, high wear resistance and other advantages, and may be used a the rut resisting material for asphalt road.
Description
Technical field
The invention belongs to the material technology field, be specifically related to the track-resistant additive that bituminous pavement is used.
Background technology
Rut be bituminous pavement since vehicular load frequently, effect makes runway produce bigger permanent deformation at the wheelpath place repeatedly, and phenomenon is damaged on the road surface of the similar groove of a kind of shape that forms at bituminous pavement upper edge vehicle heading.The reason that forms rut be because overload of vehicle, the volume of traffic is excessive and engineering location summer high temperature underestimated during Pavement Design due to.In addition because road surface or compactness of subbase deficiency during excessive, the construction of oil mass during Asphalt Mixture Design, the soil compaction degree is on the low side or soil matrix in reason such as weak intercalated layer is arranged.Rut generally occurs in temperature higher season, and oil mat produces tension set and VISCOUS FLOW down and forms gradually rolling repeatedly of vehicle.It the side direction protuberance occurs normally when following the oil mat compression subsidence.The conference that adds of the rut degree of depth strengthens the transverse horizontal component that wheel load produces, after temperature falls after rise, surface material becomes fragile, bossing with the rut limit at the bottom of the rut brings horizontal component and all may produce longitudinal slit under formed indirect flexural tensile stress effect, and the infringement meeting that road pavement causes when rainfall, snow is more serious.When rut reaches certain depth, not only can influence the steady and comfortableness of driving, and ponding in the back rut groove that rains, serious threat is to traffic safety.
Asphalt pavement rut is one of primary highway disease of China.In recent years, increase considerably though modifying asphalt, modified asphalt SMA, modifying asphalt Superpave are used, the rut of bituminous pavement does not obviously reduce.
Anti-rut agent is a kind of multicomponent Chemicals, mixes the slip resistance and the non-deformability that can significantly improve bituminous pavement in the asphalt, thereby can stop or delay the generation of rut.
The early stage research of raising of the anti-rut performance of asphalt high temperature mainly concentrates in the directly modification to bituminous material, and by the research that the modification to asphalt improves its anti-rut performance be nearly more than 10 years inchoate.The research of asphalt modification technology starts from the sixties in 20th century.At that time, two swedish company had been developed and a kind ofly by admixture rubber powder in asphalt it had been carried out the dry method upper layer compound of modification, and name of product is RUBITTM.The later stage seventies has been applied for United States Patent (USP) by U.S. four seasons paving company (ALL SEASONS SURFACING CORPORATION).Owing to exist rubber grain with gather materials or pitch can not be compatible fully, reason such as compound compacting difficulty, make the application of this product be subjected to very big restriction, fail to obtain to promote always.The end of the nineties, the U.S. has obtained success in the research aspect the asphalt modification technology, by using for reference the successful experience of the U.S., many in the world companies have obtained success in the product of developing the asphalt modification, after this developed again and be exclusively used in the product that improves the mixture anti-rutting performance, shell SEAM asphalt additive produced in USA is arranged, the DUROFLEX asphalt additive that Germany produces, the asphalt PRI PLAST series additive product that France produces.The common feature of these asphalt mixture anti-rutting products is in the world: it is remarkable, easy to use to improve the mixture anti-rutting performance, but the selling price costliness makes promoting the use of of these products be restricted.
China had also obtained some achievements to the research of asphalt mixture anti-rutting agent in recent years, " mix the research of fiber asphalt Asphalt Mixture outward " etc. as western transport science and techonologies project " technical study that waste rubber powder is used to build the road ", Sichuan Province transportation department science and technology item, but up to the present, matured product does not appear in the newspapers yet.Therefore, strengthening the development of anti-rut agent Products Development, is to need a urgent technical problem that solves in the current asphalt roads construction.
