[0003] The anti-cracking construction method of asphalt pavement splicing is the construction method of widening and splicing the asphalt pavement. At present, the construction method of widening and splicing the asphalt pavement is directly carried out by tearing off the release paper when installing the waterstop waterstop at the splicing position. Bonding, poor bonding stability, prone to deformation, and poor adhesion of the waterstop, which seriously affects the waterproof effect of the waterstop, reduces the quality of the widening and splicing of the asphalt pavement, and leads to widening and splicing of the asphalt pavement cracking

Embodiment Construction
[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0035] Such as figure 1 As shown, a crack-resistant construction method for asphalt pavement splicing includes the following construction steps:
[0036] S1: Milling of asphalt pavement base, use milling machine or cutting machine to carry out milling construction, set up splicing pits on one side of asphalt pavement, and use milling machine on the side of splicing pits that fits with asphalt pavement Or the cutting machine cuts out the splicing steps;
[0037] S2: Material selection, according to the depth and width of asphalt pavement splicing pit milling, select double-sided water stop strips and fiberglass grids that are suitable for the width;
[0038] S3: Gra...

The invention discloses an anti-cracking construction method for asphalt pavement splicing. The construction method comprises the following construction steps: asphalt pavement base layer milling, material selection, base layer facade treatment, adhesive layer oil coating, water stop belt and glass fiber grating installation and asphalt mixture paving. When a water-stop belt is installed, the water-stop belt is baked in advance through a baking gun for softening treatment. After being softened, the water-stop belt is uniformly hammered and attached through a rubber hammer and fitting effect ofthe water-stop belt is improved. After bonding, the water-stop belt is integrally fixed through nylon nails to improve the stability of a water injection zone and prevent occurrence of offsets, the water seepage prevention effect of the water-stop belt is obviously enhanced; the asphalt pavement widening and splicing quality is improved, the asphalt pavement widening and splicing position is prevented from cracking, and when the asphalt pavement base layer is milled, the surface layer and the base layer of the asphalt pavement are subjected to layered milling construction, so that the qualityof recycled materials is not influenced, and the asphalt pavement widening and splicing quality is improved.
Description
technical field [0001] The invention relates to the technical field of asphalt pavement splicing, in particular to an anti-crack construction method for asphalt pavement splicing. Background technique [0002] Asphalt pavement is various types of pavement formed by paving and rolling asphalt concrete. Asphalt concrete is a mixture of asphalt materials with a certain viscosity and an appropriate amount and a certain grade of mineral aggregates, which are fully stirred. , Asphalt concrete, as an asphalt pavement material, must bear the repeated action of vehicle loads and the long-term impact of environmental factors during use. Therefore, asphalt concrete must have good resistance to natural factors while having a certain bearing capacity. Durability, asphalt binder improves the ability of paving aggregates to resist damage to the road surface caused by driving and natural factors, making the road surface smooth, less dusty, impermeable and durable. Therefore, asphalt paveme...
