Embodiment Construction

[0045] The following is attached Figure 1-7 The application is described in further detail.

[0046] The embodiment of the present application discloses a construction technology of an asphalt pavement structure.

[0047] refer to figure 1 and figure 2 , a kind of asphalt pavement structure construction technology, comprises the following steps:

[0048] S1, laying the stable base 1, laying the cement stabilized base 1 on the road surface;

[0049] S2, laying the connection structure 2, the connection structure 2 includes connection nails 21 and glass fiber mesh 22;

[0050] 1. Forming connecting nail 21 (refer to image 3 ), the connecting nail 21 includes a pointed nail column 211, and the middle part of the nail column 211 is provided with a through groove 211 along its length direction, so that the nail column 211 is divided into two insertion parts, and both sides of the through groove 211 are fixed with The blocking protrusions 212 that can abut against each othe...

Abstract

The invention relates to an asphalt pavement structure construction process. The process comprises the following steps: S1, paving a stable base layer; S2, paving a stable base layer; S3, paving an asphalt lower surface layer; S4, paving a rib net; and S5, paving an asphalt upper surface layer. The process has the effects that the connecting strength between the asphalt surface layer and the stable base layer is improved, the continuity of the pavement is enhanced, the bearing capacity and deformation resistance of the asphalt concrete pavement structure are improved, and structural damage cracks of the asphalt pavement are limited.

Description

technical field [0001] The present application relates to the field of road engineering, in particular to a construction technique of an asphalt pavement structure. 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] Semi-rigid base asphalt pavement is the main type of pavement structure of high-grade highways and municipal roads in my country. Semi-rigid base refers to the base paved with inorganic binder stabilized soil that can be formed into a board and has a certain bending strength, that is, the base paved with inorganic binder stabilized aggregate or soil materials, which mainly includes The stabilized ba...
