specific Embodiment approach 1

[0030] Embodiment 1: The continuous prefabricated asphalt pavement in this embodiment is composed of a prefabricated asphalt pavement slab, an upper layer 6, a cushion layer 7 and a soil foundation 8;

[0031] The cushion layer 7 is arranged on the upper surface of the soil foundation 8, the prefabricated asphalt road slab is arranged on the upper surface of the cushion layer 7, and the upper layer 6 is arranged on the upper surface of the prefabricated asphalt road slab and bonded by an emulsified asphalt adhesive;

[0032] The prefabricated asphalt road slab is composed of a plurality of prefabricated slab units; the prefabricated slab unit is composed of a base layer 1, a lower layer 2 and a middle layer 3; the lower layer 2 is arranged on the upper surface of the base layer 1 and bonded by an emulsified asphalt adhesive , the side of the lower layer 2 is set on the inner side of the side of the base layer 1, the middle layer 3 is set on the upper surface of the lower layer ...

specific Embodiment approach 2

[0037] Specific Embodiment 2: The difference between this embodiment and Specific Embodiment 1 is that the double-tenon coupling block is composed of two tenons 5 with the same shape and matched with the tenon groove 4. One end of the tenon 5 is a larger end surface, and the other end is The smaller ends of the two mortises 5 are relatively fixed. Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0038] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the tenon groove 4 is a trapezoidal groove, and the smaller bottom side of the tenon groove 4 is an opening. Other steps and parameters are the same as those in the first embodiment.

Abstract

The invention discloses a continuous prefabricated asphalt pavement and a construction method thereof, and relates to a prefabricated asphalt pavement and an installation method thereof. The continuous prefabricated asphalt pavement and the construction method thereof aim to solve the problems that an existing prefabricated asphalt pavement slab is prone to generate a reflection crack and is low in construction efficiency. The prefabricated asphalt pavement is composed of a prefabricated asphalt pavement slab, an upper surface layer, a cushion layer and a soil foundation; and the prefabricatedasphalt pavement slab is arranged on the upper surface of the cushion layer, the upper surface layer is arranged on the upper surface of the prefabricated asphalt pavement slab and the upper surfacelayer and the prefabricated asphalt pavement slab are bonded through emulsified asphalt adhesive, and a gap between adjacent lower surface layers and a T-shaped joint between adjacent middle surface layers are filled with asphalt mixture. The method comprises the following steps of manufacturing prefabricated slab units and dual-tenon joint blocks in a prefabricated field, paving the soil foundation on a construction site, laying the cushion layer on the soil foundation, assembling the prefabricated asphalt pavement slab, and paving the upper surface layer. The continuous prefabricated asphaltpavement has good flatness, integrity and continuity, the reflection crack is reduced, the durability is good, and the construction period is short; and the continuous prefabricated asphalt pavementand the construction method thereof are suitable for asphalt pavement paving.

Description

technical field [0001] The invention relates to a prefabricated asphalt pavement and its installation method. Background technique [0002] Asphalt pavement is widely used in municipal roads and expressways in our country due to its advantages of high flatness and strong comfort. At present, the construction technology of cast-in-place asphalt pavement mainly has problems such as long construction period, difficulty in controlling construction quality, and environmental pollution. First of all, the construction period of asphalt pavement is seriously affected by weather and temperature, the construction procedure is low in automation, and the base construction and maintenance time is long, resulting in a long construction period. Secondly, the construction technology of cast-in-place asphalt pavement is difficult to precisely control the construction process due to the long distance of material transportation and serious differences in the construction environment, which in...
