Problems solved by technology

[0005] But at the same time, there are still many problems in the actual application of permeable asphalt mixture: poor durability, because of its large void ratio, it is easy to be eroded by water, aging the asphalt film and accelerating road damage; high production cost, High viscosity modified asphalt is used in permeable asphalt mixture, and the cost of raw materials is high; the mixing time is longer than that of ordinary asphalt mixture, and the mixing temperature is higher than that of ordinary asphalt mixture, so the production cost is high; the maintenance cost is high, and the permeable asphalt mixture is used in summer. Under the load of the vehicle, it is easy to produce rutting

Embodiment 1

[0025] First, heat the finished SBS modified asphalt to a molten state in an oven at 165°C, and then preheat 11,760g of coarse and fine aggregates and 240g of mineral powder (limestone with a particle size below 0.075mm) in an oven at 195°C for more than 6 hours for heat preservation. Heat to the mixing temperature of 170°C, then add 11760g of preheated coarse and fine aggregates (the mass of 1# material, 2# material, 3# material and 4# material are 3960g, 5640g, 660g, 1500g respectively) and mix Mix in the pot for 15 seconds, add 36g of chopped basalt fiber and 50.1g of HVA high-viscosity agent and mix for 90 seconds, add 552g of the above-mentioned SBS modified asphalt for heat preservation and mix for 90 seconds, mix in 240g of preheated mineral powder and mix In 90s, the rutting slab test piece was formed by rolling and forming with a wheel roller forming machine to prepare the rutting slab mixed with chopped basalt fiber OGFC-13 asphalt mixture; the asphalt-asphalt ratio w...

Embodiment 2

[0027] First, heat the finished SBS modified asphalt to a molten state in an oven at 165°C, and preheat 3920g of coarse and fine aggregates and 80g of mineral powder (limestone with a particle size of 0.075mm or less) in an oven at 195°C for more than 6 hours for heat preservation. Heat to the mixing temperature of 170°C, then add 3920g of preheated coarse and fine aggregates (the mass of 1# material, 2# material, 3# material and 4# material are 1320g, 1880g, 220g, 500g respectively) and mix Mix in the pot for 15 seconds, add 12g of chopped basalt fiber and 16.7g of HVA high-viscosity agent and mix for 90 seconds, add 192g of the above-mentioned SBS modified asphalt for heat preservation and mix for 90 seconds, mix in 80g of preheated mineral powder and mix In 90s, the Marshall test piece was prepared by the compaction method, and the Marshall test piece was formed by the asphalt mixture mixed with chopped basalt fiber OGFC-13; the asphalt-asphalt ratio was 4.8%.

Abstract

The invention discloses a preparation method of an OGFC (Open Graded Friction Course)-13 asphalt mixture doped with short-cut basalt fiber. The method comprises the following steps: firstly heating finished SBS-modified asphalt in a drying oven at 165 DEG C till the SBS-modified asphalt is in a molten state, respectively preheating coarse and fine aggregate in mineral aggregate and mineral powder for six hours or more at 195 DEG C, heating a mixing pot till the mixing temperature reaches 170 DEG C, firstly adding the preheated coarse and fine aggregate into the mixing pot for mixing for 15-18 seconds, then doping short-cut basalt fiber and HVA (High-Viscosity Agent) for mixing for 90 seconds, adding the SBS-modified asphalt subjected to heat preservation for standby for mixing for 90-95 seconds, and finally doping the preheated mineral powder and mixing for 90-95 seconds to prepare the mixture. According to the prepared OGFC-13 asphalt mixture, a proper amount of short-cut basalt fiber is doped into the asphalt mixture, so that the water stability can be improved; meanwhile, the high-temperature-resistant stability can also be improved; the method is simple and convenient to operate; the cost is reduced.

Description

technical field [0001] The invention belongs to the research field of road building materials, and in particular relates to a preparation method of asphalt mixture mixed with chopped basalt fiber OGFC-13. Background technique [0002] Open Graded Friction Course (OGFC for short) refers to paving with asphalt mixture with large void ratio, which can quickly drain rainwater from the inside of the road surface, and has anti-skid, noise reduction, anti-glare, The road paving material that seeps into one body is generally used as the upper layer or the upper layer and the middle layer of the drainage pavement. With the application and popularization of drainage pavement, the use of OGFC as the most important surface material of drainage pavement has increased sharply. [0003] With the rapid development of my country's economy, the traffic conditions of expressways present the characteristics of heavy load, high flow and obvious channelization, and the quality requirements for a...
