Description
Technical field:
The present invention relates to a kind of method of using waste tire rubber pitch synchronous sealing according to ballast grain sizes.
Background technology:
The bitumen macadam seal coat technology was invented in Europe in the 1950's synchronously, be that easy pitch (mulseal) spreading and artificial spade scatter 0～10MM rubble (or river sand) at first, with the method for the early stage illnesss in road surface such as redeck be full of cracks fast, weary oil, pitted skin; Along with science and technology development, just have the higher pitch sprinkling of mechanization degree (mulseal) car and road-metal spreading machine at the initial stage eighties, efficiency of construction improves greatly; But because the restriction of material development at that time, this job practices only is used for the maintenance and the build on town and country road, rural road; Through the eighties and the nineties material science and technology fast development, particularly electronic computer technology under promoting electromechanical integration technology and the development of modified emulsifying asphalt material technology and equipment make the technical level of bitumen emulsion equipment, pitch (mulseal) distribution vehicle and road-metal spreading machine that the variation of matter arranged; Cause the construction quality of this construction technology can satisfy the different brackets highway and maintain requirement in early days and since this construction technology fast and efficiently advantage caused developing rapidly and promoting of this maintenance technology, the improving constantly of equipment and technology level.Spill cloth and rubble spreading incorporate synchronous bitumen macadam seal coat machine and modified bitumen (mulseal) production equipment at the pitch (mulseal) that electronic computer control has appearred in German and the U.S. simultaneously the latter stage nineties; The pressure of this synchronous each shower nozzle of bitumen macadam seal coat equipment and flow all are independent control, the sprinkling amount of pitch (mulseal) and every square metre rubble spreading amount travel speed along with automobile chassis under the control of computer are regulated automatically, its error is very little with setting value, and each shower nozzle of its precision can reach ± and 5g/min, every square metre of rubble spreading precision can reach ± and 1%; Because modified bitumen and the appearance of modified emulsifying asphalt and the interpolation of fortifying fibre makes this construction technology be applicable to different grade maintenance of surface and maintenance; Now, this technology is in the U.S., and Europe and Japan and other countries are used widely, and all there is the crushed stone sealing equipment of multiple pattern various countries.
The synchronous surface dressing machine, with hard pitch (during sprinkling the temperature of heat modification pitch should reach 170a! More than the C) with the even building stones of clean dried almost simultaneously (in the 1s) be sprayed on the road surface, assurance pitch is finished in the shortest time with building stones and is combined, and the effect of outer load constantly forms intensity, aggregate paves when stopping, paving of asphalt binder stops automatically, do not have the asphalt binder course of waiting for aggregate.In conjunction with the time, spray temperature is 170 ℃ a polymer modified asphalt, in conjunction with the time temperature also can guarantee more than 165 ℃, the flowability of asphalt binder is still fine, because the surface tension of fluid asphalt, make the heated bitumen rise of climbing along the building stones surface be about 2/3 of building stones height, and form the one and a half months face on the building stones surface, make building stones be reached 70%, guaranteed that pitch and building stones have enough bond strengths by the area that pitch wraps.Simultaneously, the hair attraction of pitch can produce a concave surface, and mobile well pitch enters in the microcosmic texture of aggregate surface, like inlaying jewelry, does not therefore have aggregate and runs off between this concave surface and aggregate.Roll by natural traffic bound or rubber-tyred roller then and form the individual layer bituminous macadam.Use mainly as road surface table place seal, also can be used for the surface construction of low-grade highway.Synchronous pavement surface dressing has shortened that cementing agent sprays and the interval between the spreading of gathering materials, and has increased the area that wraps of aggregate particle and cementing agent, and easier assurance stable proportionate relationship between them has improved operating efficiency, has reduced construction cost.The bitumen macadam seal coat technology mainly contains following advantage synchronously:
1) synchronous surface dressing is the technology that low-yield asphalt binder infiltrates the substrate surface microcrack smoothly, plays good joint seal effect.
2) synchronous surface dressing essence is by certain thickness asphalt membrane (the ultra-thin asphalt macadam top dressing layer of 1～2MM) bonding, its whole mechanical characteristics is flexible, can increase the road surface cracking resistance, cure the road surface net crack, reduce the road reflection crack, improve road surface percolation-proof performance, be used for road maintenance and can prolong service life of road surface more than 10 years, if use high viscosity binding material effects such as polymer modified asphalt, rubber asphalt better.
3) as the water shutoff layer of newly-built semi-rigid asphalt pavement, outstanding water sealing effect is arranged not only, and the reflection crack of semi-rigid type base is had significant retarding action.
4) synchronous surface dressing can improve the friction factor on former road surface greatly, promptly increases the road surface non-skid property, and can make surface evenness obtain to a certain degree recovery.
5) by adopting the job practices of local multilayer pouring different-grain diameter building stones, synchronous surface dressing can effectively be cured diseases such as reaching the above rut of 10cm, depression deeply, and this point is that the general maintenance method is incomparable.
6) synchronous surface dressing can be used as the transiens road surface of low-grade highway, to alleviate the contradiction of highway construction fund wretched insufficiency.
7) the synchronous surface dressing operation is simple, speed of application is fast, immediately the speed limit open to traffic.
8) no matter be used for road maintenance still as the transiens road surface, the ratio of performance to price of synchronous surface dressing obviously is better than other table prescribing methods, thereby reduces the maintenance cost of road greatly.
Yet there is following shortcoming in present technique at present: in the process of synchronous sealing, rubble is too much, and it is overlapping to understand appearance behind the spreading, is that rubble and junked tire asphalt membrane are wrapped up in attached deficiency, and adhesion stress descends;
Rubble is very few, and the junked tire asphalt membrane is blocked up, after road roller rolls, sticking wheel phenomenon can occur.
Technology controlling and process is a difficult problem in concrete practice process.
