Problems solved by technology

SMA (asphalt mastic macadam) asphalt pavement is such a pavement. Theoretically speaking, its anti-rutting performance is very strong. Relatively low, unstable performance of mechanical equipment, relatively low softening point of binder, material segregation and other factors lead to relatively insufficient anti-rutting performance of SMA asphalt pavement. The fact is that SMA asphalt pavement also often appears rutting

Embodiment 1

[0027] Conditions of this embodiment: the first layer of asphalt and gravel are sprinkled (scattered) in an asynchronous manner, the sprinkled asphalt is hot asphalt, and the modified emulsified asphalt with an oil content of 60% is used for mixing. Department; 3: Model) type slurry mixture is used as the penetrating material, and FH-40 modified emulsified asphalt slurry mixture is used as the maintenance overlay for the penetrating asphalt pavement.

[0028] During the specific implementation, the first steps to be carried out are as follows:

[0029] 1. Carry out the material design of FH-40 modified emulsified asphalt slurry mixture penetration type asphalt pavement.

[0030] FH-40 type modified emulsified asphalt slurry mixture penetrating asphalt pavement material design is divided into two parts: sprinkling (sprinkling) cloth and penetrating material:

[0031] 1. Sprinkle (sprinkle) cloth: According to research, the amount of asphalt sprinkled on the first layer is 0.4k...

Embodiment 2

[0049] Conditions of this example: use the first layer of asphalt and gravel to sprinkle (sprinkle) cloth in a synchronous manner, use hot asphalt for spreading asphalt, use modified emulsified asphalt for mixing, oil content is 60%, and use MS-2 type slurry mixture Used as penetrant to fill 40mm deep ruts.

[0050] During the specific implementation, the first steps to be carried out are as follows:

[0051] 1. Carry out the design of FH-40 modified emulsified asphalt slurry mixture penetration type asphalt pavement filling rut materials.

[0052] The design of FH-40 modified emulsified asphalt slurry mixture penetration type asphalt pavement filling rut materials is divided into two parts: sprinkling (sprinkling) cloth and penetrating material:

[0053] 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 20mm~40mm gravel is 40mm, which is consistent with the depth of the ...

Embodiment 3

[0071] Conditions of this embodiment: new FH-40 type modified emulsified asphalt slurry mixture penetrating asphalt pavement, semi-rigid base, emulsified asphalt with an oil content of 50% for the permeable asphalt, using permeable asphalt (the first layer Asphalt) and gravel are sprinkled (sprinkled) in an asynchronous manner, the second layer of asphalt is sprinkled with hot asphalt, and the modified emulsified asphalt with an oil content of 60% is used for mixing, and MS-3 type slurry mixture is used as the penetrating material.

[0072] During the specific implementation, the first steps to be carried out are as follows:

[0073] 1. Carry out the material design of FH-40 modified emulsified asphalt slurry mixture penetration type asphalt pavement.

[0074] FH-40 type modified emulsified asphalt slurry mixture penetrating asphalt pavement material design is divided into two parts: sprinkling (sprinkling) cloth and penetrating material:

[0075] 1. Sprinkle (sprinkle) fabri...

Abstract

The invention provides a mixture for constructing an emulsified asphalt and dilute slurry mixture bituminous penetration road. The mixture is an FH-40 type mixture, and the bituminous road constructed by using the mixture can achieve an effect of preventing tracks. The mixture can be used for maintenance of new roads and constructed roads, and can also be used as a protective layer, a wearing layer and an anti-skid layer and used for paving a bridge deck, beautifying, preventing noise and filling tracks. In the emulsified asphalt and dilute slurry mixture bituminous penetration road, the maximum gravel diameter of the aggregate is consistent with the thickness of the road; a suspended compact bituminous mixture, which forms skeletons and is padded between the skeletons and formed by gravels of other diameters and bituminous cement, is a unity of a skeleton structure and a suspended compact structure, called as a skeleton-suspended compact composite structure, abbreviated as a composite structure and expressed as 'FH'; and 40 expresses that the maximum diameter of the scattered gravel is 40mm, and is also the thickness of the road.

Description

technical field [0001] The invention relates to materials used in asphalt pavement, in particular to a mixture for building emulsified asphalt slurry mixture penetrating asphalt pavement. The asphalt pavement built with this material can prevent rutting and ensure road use quality. Background technique [0002] Most of the roads and urban roads that have been built in my country are asphalt roads. Due to the serious overloading of vehicles, large traffic volume, channelized driving, and high temperature weather, rutting has become the most important disease in the early stage of asphalt pavement, such as the climbing section of the expressway, the BRT (Bus Rapid Transit) lane and Rutting is the most likely and serious place on the guide road, etc. According to the data, 80% of the asphalt pavement has different degrees of rutting. It is a stubborn disease in road diseases and has not been solved. [0003] At present, the typical asphalt pavement structure is divided into th...
