Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the layers are only bonded together through the adhesive layer, and during the acceleration or sudden braking of the driving vehicle, a large horizontal shear stress will be applied to the road surface, causing the layers to be separated from each other. Misaligned separation between layers, resulting in road damage

Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0048] Such as figure 1 As shown, an asphalt pavement includes a soil layer 1, a graded crushed stone layer 2, a concrete layer 3 and an asphalt layer 4 from bottom to top.

[0049] Such as figure 2 As shown, the concrete layer 3 is laid with steel mesh 5 along the horizontal direction, and the crack resistance of the concrete layer 3 is improved through the steel mesh 5 . Each node of the reinforcement mesh 5 is bound with a vertically upward stainless steel rod 6 , and the lower end of the stainless steel rod 6 passes through the graded crushed stone layer 2 and is inserted into the soil layer 1 . The upper end of the stainless steel rod 6 extends to the middle of the asphalt layer 4, and an external thread is formed outside the upper end. The upper end of the stainless steel rod 6 is threadedly connected with a hemispherical hollow casing 7, and a thro...

Abstract

The invention relates to the technical field of road construction, in particular to an asphalt pavement and a construction method thereof. The asphalt pavement has the advantages that the road is not easy to damage. The asphalt pavement sequentially comprises a soil layer, a graded gravel layer, a concrete layer and an asphalt layer from bottom to top, a concave hemispherical groove is formed in the upper surface of the concrete layer, and a hemispherical bulge corresponding to the hemispherical groove is formed in a position, corresponding to the hemispherical groove, of the asphalt layer. The hemispherical groove is formed in the concrete layer to cooperate with the hemispherical bulge of the asphalt layer, so as to achieve the effect of tightly combining the concrete layer and the asphalt layer. Meanwhile, the mutually cooperatively inserted structure of the concrete layer and the asphalt layer can also play a role in preventing dislocation between the concrete layer and the asphalt layer.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to an asphalt pavement and a construction method thereof. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the road smooth, less dusty, impermeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. [0003] The existing utility model patent with authorized notification number CN203270399U discloses an asphalt pavement, which consists of a warm-mixed asphalt mastic macadam layer, a high-modulus asphalt mixture layer, and an emulsified asphalt factory-mixed cold-mixed asphalt pavement from top to bottom. Reclaimed course, rubberized asphalt stress absorbing course and base course. [0004] The above-mention...
