Durable asphalt pavement and construction method thereof

Abstract

The invention discloses a durable asphalt pavement. The durable asphalt pavement comprises a soil base, a cushion layer, a fabricated concrete slab layer, a reinforced layer and a surface layer whichare sequentially arranged from bottom to top, wherein the fabricated concrete slab layer is formed by splicing a plurality of prefabricated slab units in the longitudinal direction of a road; each prefabricated slab unit comprises a drainage concrete base layer and a top layer which is arranged above the base layer and is bonded through a bonding agent; the reinforced layer is arranged on the topsurface of the fabricated concrete and comprises a plurality of net supporting units extending in the length direction of the road; the surface layer comprises a drainage part and a waterproof part except the drainage part; and a protection slope is arranged on the outer side face of a stone plate, and a plurality of flow guide holes are formed in the road extending direction at intervals. The invention discloses a construction method of the durable asphalt pavement. The asphalt pavement structure has the beneficial effects that effective drainage is achieved, and meanwhile the overall durability of the asphalt pavement structure is improved.

Description

technical field [0001] The invention relates to the field of road construction. More specifically, the present invention relates to a durable asphalt pavement and its construction method. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials added to mineral materials, and is a widely used pavement in existing road construction. Especially with the continuous development and construction of the city, public buildings, housing, road construction, etc. harden the surface environment and destroy the surface water cycle. In order to change the status quo of the water cycle in the city, the construction of a sponge city is currently advocated to strengthen the city's water absorption when it rains , The ability of water storage and seepage. [0003] When the porosity of the pavement material is designed to be 18-25%, it has good drainage performance. The drainage asphalt pavement adopts large-pore open-graded large-parti...

Problems solved by technology

[0003] When the porosity of the pavement material is designed to be 18-25%, it has good drainage performance. The drainage asphalt pavement adopts large-pore open-graded large-particle-size asphalt mixture, which is a new pavement form to achieve this goal. However, due to the overall structure The large porosity leads to a relatively low ability of the overall pavement to resist vertical loads and stable loads, and it is easily affected by the air and ultraviolet rays of the sun to accelerate the aging of asphalt, resulting in poor pavement durability
