Embodiment 1
[0062] Conditions of this embodiment: the first layer of asphalt and gravel are sprinkled (scattered) in an asynchronous manner, the asphalt is spread with hot asphalt, and the oil content for mixing (the content of evaporation residue components mainly refers to the content of asphalt including modifier components) For 60% modified emulsified asphalt, use MS-3 (MS: the abbreviation of English Micro-Surfacing is the micro-surfacing; 3: model) type slurry mixture as the penetrating material, and build a new FH-40 (40: sprinkler The maximum particle size of gravel is 40mm, which is also the thickness of the road surface) type modified emulsified asphalt slurry mixture penetration type asphalt pavement.
[0063] When implementing it, the first thing to do is to carry out the design of FH-40 modified emulsified asphalt slurry mixture penetration type asphalt pavement materials.
[0064] FH-40 modified emulsified asphalt slurry mixture penetration type asphalt pavement material des...
Embodiment 2
[0097] Conditions of this example: the first layer of asphalt is sprinkled (sprinkled) in a synchronous manner with gravel, the first layer of asphalt is sprinkled with hot asphalt, the second layer of asphalt is artificially sprinkled with modified emulsified asphalt, and the modified emulsified asphalt is used for spreading and mixing. The oil content of the emulsified asphalt is 60%, and the MS-2 slurry mixture is used as the penetrating material to fill the 30mm deep rut.
[0098] During specific implementation, the first work to be done is to design the materials used to fill the ruts.
[0099] The material design for filling ruts is divided into two parts: sprinkling (sprinkling) cloth and penetrating material:
[0100] 1) Sprinkle (sprinkle) cloth: According to research, the amount of asphalt sprinkled on the first layer is 0.3kg / m 2 ;Because the maximum particle size of 10mm~30mm gravel is 30mm, which is consistent with the depth of ruts, so choose to use 10mm~30mm gr...
Embodiment 3
[0132] Conditions of this example: serious rutting occurs on the asphalt pavement of the guide road, the original pavement is 60mm thick and fully milled, the modified emulsified asphalt with an oil content of 60% is used for spreading and mixing, and the MS-2 type slurry mixture is used as the penetration Material, use FH-60 modified emulsified asphalt slurry mixture to penetrate into asphalt pavement repair.
[0133] When implementing it, the first thing to do is to carry out the design of FH-60 modified emulsified asphalt slurry mixture penetration type asphalt pavement materials.
[0134] FH-60 type modified emulsified asphalt slurry mixture penetrating asphalt pavement material design is divided into two parts: sprinkling (sprinkling) cloth and penetrating material:
[0135] 1) Sprinkle (sprinkle) cloth: According to research, the amount of asphalt sprinkled on the first layer is 0.8kg / m 2 Modified emulsified asphalt; because the maximum particle size of 30mm-60mm gravel...
