Embodiment Construction
[0043] Attached to the following Figure 1-5 This application will be described in further detail.
[0044] The embodiments of the present application disclose a highway asphalt pavement. refer to figure 1 , including the base layer 11 , the gravel layer 12 and the pavement layer 13 laid in order from bottom to top. The foundation layer 11 is formed by pouring concrete on the foundation 1 , the foundation layer 11 is in the shape of a cuboid, and the length direction of the foundation layer 11 is consistent with the length direction of the foundation 1 . The gravel layer 12 is formed by laying gravel on the base layer 11 , and the pavement layer 13 is formed by laying asphalt on the gravel layer 12 . A water storage structure 2 is arranged on the base layer 11 , and the water storage structure 2 includes a water storage pipe 21 , a vertical plate 22 and a water permeable plate 23 . The water storage pipe 21 is a square tubular structure, the length direction of the water s...

The application relates to the technical field of asphalt pavement, and in particular to a construction method of highway asphalt pavement, which includes a base layer, a gravel layer and a pavement layer laid in sequence from bottom to top, and a water storage structure is arranged on the base layer, and the water storage structure It includes a water storage pipe, a number of vertical plates and a permeable plate. The water storage pipe is fixed on the side of the gravel layer close to the pavement layer. The side of the water storage pipe away from the base layer is provided with a through hole, and several vertical plates are fixed on the peripheral side of the through hole. On the water storage pipe, and between several vertical plates, a water absorption cavity connected with the water storage pipe is formed, the water storage pipe is filled with a water storage body, the water absorption cavity is filled with a water absorption body located on the water storage body, and the water permeable plate is fixed on the water absorption body on the side away from the reservoir. The present application has the effect of good water permeability and water storage performance of the asphalt pavement.
Description
technical field [0001] The present application relates to the technical field of asphalt pavement, in particular to a highway asphalt pavement and a construction method thereof. Background technique [0002] Asphalt pavement refers to various types of pavements that are paved with road asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage caused by traffic and natural factors, making the road smooth and less dusty. Water permeable and durable. Therefore, asphalt pavement is one of the most widely used advanced pavements in road construction. [0003] The existing Chinese patent with the publication number of CN109487655A discloses a construction method of highway asphalt pavement, which belongs to the field of municipal road construction. Mark the paving thickness of the asphalt mixture and the control baseline that guides the running direction and elevation of the paver; S3, paving and leveling, firs...
