Embodiment 1

[0036] This embodiment provides an asphalt concrete pavement structure, such as figure 1 As shown, including the soil foundation 1, the top of the soil foundation 1 is successively laid with a cushion layer 2, a base layer 3 and a surface layer 4, and a layer of filter fabric 5 is laid between the soil foundation 1 and the cushion layer 2. The filter fabric 5 adopts non-woven geotextile, and the specification is 300g / m 2 , its function is to prevent the fine soil from entering the soil foundation 1 and causing damage to the soil foundation 1. The cushion layer 2 is made of building concrete slag, and the width of the cushion layer 2 is 25cm wider than the side of the soil foundation 1. The base layer 3 is made of crushed stone slag Mixture, the width of the base layer 3 is consistent with the width of the cushion layer 2, and the width of the surface layer 4 is narrower than the side 5cm of the base layer 3 on each side; the surface layer 4 includes a lower layer 41, a middle ...

Abstract

The invention provides an asphalt concrete pavement structure and a laying technology thereof. The laying technology comprises the steps that one of crushed building concrete slag, broken stone and gravel is used as a bedding layer, a mixture of broken stone and slag or a mixture of coal cinder and slag or a mixture of broken stone, coal cinder and slag is used as a base layer, the bedding layer and the base layer can make rainwater quickly infiltrated and discharged, the water storage capacity of the bedding layer and the base layer is high, under stress, water cannot go upwards and cannot corrode asphalt concrete, and an asphalt pavement is prevented from being damaged by the water; by using the ATPB asphalt mixture, the AM asphalt mixture and the OGFC asphalt mixture as a surface layer,the rainwater can quickly infiltrate, the adhesion force of asphalt cannot be reduced, the cohesive force between asphalt and mineral aggregates in the asphalt pavement cannot be destroyed, it is ensured that the stress on the whole road structure is uniform, when the road structure is under force at the extreme temperature, the road structure is not prone to deformation, the service life is long, and the temperature stability is high.

Description

technical field [0001] The invention relates to the field of concrete roads, in particular to an asphalt concrete road surface structure and a paving process thereof. Background technique [0002] With the development of society, urban roads have now been completely hardened. Among them, the main roads and highways in cities generally use asphalt pavement. The asphalt material with a certain viscosity and appropriate amount and a certain grade of mineral aggregates are fully mixed to form a mixture. The asphalt pavement has a smooth surface, no joints, comfortable driving, low vibration, low noise, wear resistance, and no dust. With many advantages such as easy cleaning, short construction period, easy maintenance, renewable utilization, and suitable for phased construction, asphalt roads have become a high-grade pavement with the largest paving area in China. [0003] Although asphalt concrete pavement has many of the above advantages, it also has certain limitations. Ordi...
