Description
Technical field
The invention belongs to the coherent paving technical field on on-the-spot making road or aerodrome, be specifically related to which floor different materials paving of making at the scene.
Background technology
Along with the develop rapidly of China's economic construction, the construction of high-grade highway is also maked rapid progress.1985, from building Class I highway, the good speedway in China article one speedway Shanghai was open to the traffic in 1988, and the big speedway in nineteen ninety Shen is open to traffic.After this in more than ten years, the high grade highway development of China linearly increases.Up to the present, China's speedway mileage open to traffic is near 3.5 ten thousand kilometers, and high-grade highway has been broken through 300,000 kilometers, and growth momentum is very violent, but the maintenance work of high-grade highway after building up relatively lags behind.Current, various diseases have appearred on the speedway that many different times build up.Because the increase of the vehicle axle weight and the traffic volume, canalized traffic is on the rise, so rut has become one of main disease of high-grade highway flexible pavement.
Rut is that flexible pavement damages phenomenon because vehicular load acts on the road surface of a kind of shape similar " water channel " that makes runway produce bigger permanent deformation at the wheelpath place and longitudinally form frequently, repeatedly on flexible pavement.The reason that forms rut be because overload of vehicle, the traffic volume is excessive and during pavement design due to the Area during Summer high temperature at engineering place underestimates.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.It generally is in temperature higher season that rut forms, and asphalt surface course produces permanent deformation and VISCOUS FLOW down and forms gradually rolling repeatedly of vehicle.It the side direction protuberance occurs normally when following the asphalt surface course compression subsidence.If untimely processing, not only the road surface can lose the favorable service function, and disease also will continue to worsen.The conference that adds of the rut degree of depth strengthens the athwart ship force 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 crack 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 Pavement Performance and also in the back rut groove that rains ponding, automobile very easily takes place float sliding phenomenon, traffic safety is arrived in serious threat.
The classification of rut is divided into: the rut of slight rut, wearing and tearing rut, horizontal waveform rut, unstable interlayer rut, the not enough initiation of foundation base intension is several.The method of present domestic punishment rut is as follows:
The slight deformation rut can be eliminated canalized traffic by driving control, makes enforcement vehicle cross direction profiles on whole runway more even, and other has traffic bound can make the road surface recover smooth.The rut that the track produces because of excessive wear, the general fluting that adopts evenly sprays or brushing one deck pitch binder applied at bottom land and cell wall, bituminous mixture is inserted in the groove again, shakeouts and rolls.Horizontal waveform rut, the projection that employing will be higher than the road surface scabbles, and partly sprays or brushes pitch binder applied at trough, bituminous mixture is inserted trough and levelling, compacting again.For unstable interlayer and the not enough rut that causes of foundation base intension, earlier unstable interlayer or unstable basic unit are punished, then from new making surface layer.
At present, the method for domestic punishment rut roughly is divided into two kinds of the method for mending by replacing a damaged part and enthesises.These the two kinds major defects of repairing ruts are: the moat groove width that goes out in the milling of the position of asphalt pavement rut and dark, used quantity of material is big, cost is high, corollary equipment is many, complex process, progress are slow, contaminated environment, operating difficulties, wayward, the initial curing time is grown, influence traffic etc.
