Description
Technical field
The invention belongs to the ground surface material technical field, be specifically related to a kind of asphaltum with high viscosity and production method thereof and device.
Background technology
Drainage road, cement pavement covering bituminous pavement (being called for short " paracetamol "), steel construction bridge floor asphalt concrete etc., all need to use asphaltum with high viscosity.
Drainage asphalt pavement is a kind of high voidage bituminous pavement with water exhaust system.Its Main Function is: during the rainy day because it has high connectivity gap and vertically and horizontal drainage measure, make the unlikely ponding of road table, moisture film around mixture particle is also unlikely too thick, thereby played the effects such as anti-sideslip, anti-dazzle, water-mist-proof, reduced the probability of rainy day traffic accident; In addition, the mutual embedded squeezing of this road surface coarse aggregate, skeleton function is obvious, has also improved the anti-rut performance of road.
Paving Bituminous Concrete surface layer on cement concrete pavement (" paracetamol "), can improve the use function of cement pavement, improves the planeness on road surface.But the stretching action caused in contraction or the displacement of cement concrete plate horizontal direction, or the flexural tensile stress of surface layer bottom, or the vertical shearing stress located of the cement sheeting seam (crack) under action of traffic loading, all can produce reflection crack at asphalt concrete pavement, affect the work-ing life of oil mat, the destruction under low temperature condition is especially remarkable.For effectively preventing, delay, reduce the appearance of reflection crack, adopt asphaltum with high viscosity to lay one deck stress absorbing layer, be effective means.
Emerging in multitude of steel structure bridge, make bridge floor asphalt concrete become the problem of whole world research, and the appearance of asphaltum with high viscosity, for this problem many again a kind of selection.
In existing technology, the technology of relevant asphaltum with high viscosity is a lot, and many patent documentations all have report to this, as: CN101457009 B, CN1351096 A, CN1132883 C, CN19990593 A, CN101613515 B etc.The asphaltum with high viscosity production method that these patented technologies are introduced, can be generalized into three kinds of methods: 1. batch production production, the equipment of namely fixing by the whole series, produce asphaltum with high viscosity at production plant, then with special-purpose vehicle, deliver to batching plant, make the asphaltum with high viscosity concrete.2. mobile equipment production, namely pass through movably equipment of the whole series, produces near batching plant, after producing asphaltum with high viscosity, is delivered directly to batching plant, makes the asphaltum with high viscosity concrete.3. with whole plant production particulate state asphaltum with high viscosity, directly render to mixing in cylinder of batching plant, make the asphaltum with high viscosity concrete.Above production method 1,2 all needs huger whole plant, the transportation of special-purpose vehicle and heating repeatedly, and not only power consumption causes greatly and easily the aging of material, the while complex process, the production cycle is long, and relative efficiency is lower.The particulate state asphaltum with high viscosity that method 3 is produced, due to its quality product technical indicator, with the quality index of asphaltum with high viscosity compound, there is no directly inevitable dependency, must make the asphaltum with high viscosity of liquid state, could measure its quality and technical index, determine whether to prepare qualified asphaltum with high viscosity compound, therefore, the particulate state asphaltum with high viscosity, practical application fewer.
