A kind of pavement crack repairing net and its weaving method and application

Abstract

The invention discloses a pavement crack repair net and a weaving method and application thereof. The repair net is a triangular polyester net formed by weaving polyester silk and one or two types of polyester threads. The polyester materials have an abrasion-resisting property, an inflaming retarding property and an uvioresistant property. The diameter of the polyester silk is 0.2-0.9 mm. The specification of the polyester threads is 150D / 2 or 150D / 3 or 200D / 2 or 200D / 3 or 300D / 2 or 300D / 3. The repair net provided by the invention is provided with an organizational structure with stable positioning, repair structural layers and an original pavement are combined in an interinfiltration and fissure-filling mode, and the overall positioning effect is good; the repair net is of a three-dimensional type, strength belts are evenly distributed longitudinally, strength lines are transversely connected, the displacement-resisting capability is high, and the good stress absorption and dispersion function is achieved; and the repair net is provided with specific silk net structures connected through loop lines, the structural strength and deformation and impact resistance are greatly improved, and the tearing-resisting strength is enhanced.

Description

technical field [0001] The invention belongs to the technical field of road surface repair, and in particular relates to a road surface crack repair net and its weaving method and application. Background technique [0002] In recent years, my country's road construction has developed rapidly, especially asphalt roads are spread all over cities and villages. With the continuous development of new materials, new techniques and new equipment for the construction of asphalt highway pavement, the quality of asphalt highway pavement has been continuously improved. [0003] The current asphalt road surface is smooth and safe to use, noise elimination and vibration prevention, wear resistance and displacement resistance, pavement stability and fast construction, pavement life and maintenance, road environment and construction, and biodiversity protection around the road. All things considered, great progress has been made. [0004] In the maintenance of urban roads, expressways, o...

Problems solved by technology

Untwisted micro-filaments are currently used for glass fiber cloth, and the single-filament diameter is several microns to more than ten microns. Glass fiber micro-filaments have poor wear resistance, high brittleness, and low shear strength. The woven fabric is resistant to tensile fracture. The mechanical properties such as tear resistance, burst resistance, wear resistance, impact resistance or shear resistance need to be further improved, and are easy to be damaged and torn; the quadrilateral structure of glass fiber cloth is unstable and easy to deform, and it is easy to break and slip after deformation. It is easy to produce shear movement and ridges under load, so it is necessary to seek materials and meshes with stable textures; glass fiber cloth is a dense fabric with relatively small or almost no meshes, and the dressing layer formed with asphalt macadam and the maintenance road surface If the combination is not in place, it will affect the repair of cracks; this kind of structural layer has poor drainage, which may cause local water accumulation and affect the quality of pavement repair; the fiberglass cloth is narrow, and the road repair rate is not high; glass fiber cloth is easy to produce irritation to human skin , construction workers must wear protective gloves

Due to the fact that cracks are easy to form in the current road surface application, the phenomenon of displacement and heaping occurs, ruts and track marks exist, and the vehicle’s heavy axle load increases, so that safety hazards cannot be completely cured, and the cost of vehicle operation and road maintenance increases. These problems exist And the urgent need to solve, stimulate the continuous development of new materials, new technology and new equipment for road construction

[0006] In the prior art, steel wires are also used on roads. The existing plastic-steel grids cover steel wires in plastics during processing. This material is mainly used for roadbed reinforcement under water-stabilized layers, and cannot be used for road surface cracks. repair
