Detailed Description
The present utility model will be described in further detail with reference to examples. The following examples are only for the purpose of illustrating the utility model and are not intended to limit the scope of the utility model.
The utility model provides a pouring type semi-flexible anti-rut pavement structure for a station interval of an electronic guide rubber wheel system, which mainly comprises a base layer and a surface layer. As shown in fig. 1, the pavement structure comprises a base layer 1, an asphalt bonding layer 2, a lower sealing layer 3, a lower layer 4, an asphalt bonding layer 2, a middle surface layer 5, an asphalt bonding layer 2 and an upper surface layer 6 which are sequentially paved from bottom to top.
The base layer 1 can be formed by paving continuous reinforced concrete or cement stabilized macadam. As shown in fig. 2, as a preferred embodiment of the present utility model, the base layer 1 is formed by paving continuous reinforced concrete, and has a thickness of 22cm, so that a solid foundation can be provided for the asphalt pavement, structural rutting can be avoided, and meanwhile, the structural thickness of the asphalt pavement can be effectively reduced. In other embodiments of the utility model, the base layer 1 may also be designed to be laid with cement stabilized macadam, the base layer 1 laid with cement stabilized macadam preferably being designed to have a thickness of 40cm. The lower layer 4 is formed by paving coarse dense graded asphalt concrete AC-25, and the thickness of the lower layer is 8cm. The middle surface layer 5 is formed by paving medium-sized dense-graded asphalt concrete AC-20, and the thickness of the middle surface layer is 6cm. The upper layer 6 includes an upper poured semi-flexible layer 61 and a lower hollow steel wire mesh 62, wherein the poured semi-flexible layer 61 is formed by pouring cement-based grouting mortar from porous parent asphalt concrete, and the upper wall surface of the hollow steel wire mesh 62 is provided with a plurality of holes 620 (see fig. 3 and 4), and the holes 620 are communicated with the internal voids of the hollow steel wire mesh 62. Wherein, cement-based grouting materials and hollow steel wires are all commercially available. The application amount of each asphalt binder layer 2 was 0.4L/m 2.
In construction, cement-based grouting mortar is poured into the parent asphalt concrete to form poured semi-flexible layer 61. The cement-based grouting material is high-performance grouting material of G30B in the family of high-performance grouting material of the family of high-quality gravel, which is developed by Zhejiang Wei Hua novel building materials, and is mixed with water according to a water-cement ratio of 0.24 to form cement-based grouting material mortar. The amount of the coarse aggregate and the fine aggregate in the mother asphalt mixture is 84.2%, the amount of the mineral powder is 3.0% and the amount of the asphalt is 2.5%. The thickness of the poured semi-flexible layer 61 is controlled to be 4-8 cm, and the higher the thickness is, the stronger the rut resistance is. When the mortar is poured into the matrix asphalt concrete to form the poured semi-flexible layer 61, the mortar flows into the hollow steel wire mesh 62 through the hole bodies 620, and the poured semi-flexible layer 61 is bonded with the hollow steel wire mesh 62 as a whole. As shown in fig. 4, the voids in the hollow wire mesh 62 and the hole 620 in the upper wall are blocked by the mortar flowing into the poured semi-flexible layer.

The base layer of the paved surface layer is flat, firm, clean, dry and bath, and the elevation and the transverse slope are satisfactory; before paving, uniformly spraying the adhesive layer asphalt by adopting an asphalt sprayer, and constructing according to the coating weight standard of 0.4L/m < 2 >; the paving temperature of the matrix asphalt mixture is preferably 155-165 ℃. The matrix asphalt mixture achieves high compactness and flatness by rolling, and meanwhile, the void ratio of the mixture is ensured to be 20% -30%; when grouting is carried out, the surface temperature of asphalt before grouting mortar is not more than 35 ℃, the construction environment temperature is required to be 5-35 ℃, and construction is recommended at night in high-temperature days in summer. Mortar cannot be poured in rainy days. After 5-10 minutes after pouring, when no bubbles come out of the gaps of the asphalt mixture, the mortar is filled in the gaps of the asphalt mixture, and the mortar can be scraped; after grouting construction is finished, the semi-flexible pavement needs to be subjected to health maintenance for a certain time, and in the health maintenance period, a building is required to be made on site, so that people and vehicles are prohibited from walking. When the construction temperature is below 30 ℃, a special health maintenance mode is not needed; at a temperature of 30℃or higher, it is necessary to use a plastic film for curing.
The above examples are provided for further illustration of the application and are not intended to limit the scope of the application in any way: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
