Problems solved by technology

However, due to the influence of the environment and vehicle loads on the asphalt concrete pavement during use, various early diseases, such as cracks, ruts and potholes, etc., gradually appear, among which cracks are the most common and most important form of disease, and micro cracks are the early development of pavement cracks State, if not controlled, will often lead to more serious damage
The current potting materials are generally only for wide cracks due to their high viscosity, and there is no repair material specifically for micro cracks

Embodiment 1

[0018] Put 8g of epoxy resin, 4ml of methacrylic acid, 0.5ml of N,N-dimethylaniline, 50ml of methyl methacrylate, 15ml of butyl methacrylate, and 3.5g of asphalt into a three-necked flask , stir and mix evenly with a high-speed homogenizer at room temperature, put it in an oil bath at 90°C, take it out after reacting for 3 hours, cool to room temperature, add 1.6g of benzoyl peroxide, 3.5g of inorganic filler (quartz powder 0.66g, mineral powder 1.77g, talc powder 0.56g, titanium dioxide 0.51g), 0.5ml of γ-aminopropyltriethoxysilane and 0.5ml of N,N-dimethylaniline, with a high-speed homogenizer Stir and mix evenly to obtain a low-viscosity asphalt pavement micro-crack quick repair material.

[0019] Depend on figure 1 It can be seen that the curing reaction of the repair material is very rapid, and the viscosity increases exponentially. When the curing time is 13 minutes, the viscosity of the repair material has reached 177mPa·s, that is, the repair of micro-cracks needs to...

Embodiment 2

[0021] Put 7g of epoxy resin, 3ml of methacrylic acid, 0.4ml of N,N-dimethylaniline, 40ml of methyl methacrylate, 10ml of butyl methacrylate, and 3.5g of asphalt into a three-necked flask , stir and mix evenly with a high-speed homogenizer at room temperature, put it in an oil bath at 90°C, take it out after reacting for 3 hours, cool to room temperature, add 1.4g of benzoyl peroxide, 3.5g of inorganic filler (quartz powder 0.66g, mineral powder 1.77g, talc powder 0.56g, titanium dioxide 0.51g), 0.5ml of γ-aminopropyltriethoxysilane and 0.4ml of N,N-dimethylaniline, using a high-speed homogenizer Stir and mix evenly to obtain a low-viscosity asphalt pavement micro-crack quick repair material.

Embodiment 3

[0023] Put 10g of epoxy resin, 6ml of methacrylic acid, 0.7ml of N,N-dimethylaniline, 60ml of methyl methacrylate, 20ml of butyl methacrylate, and 3.5g of asphalt into a three-necked flask , stir and mix evenly with a high-speed homogenizer at room temperature, put it in an oil bath at 90°C, take it out after reacting for 3 hours, cool to room temperature, add 2.0g of benzoyl peroxide, 3.5g of inorganic filler (quartz powder 0.66g, mineral powder 1.77g, talc powder 0.56g, titanium dioxide 0.51g), 0.5ml of γ-aminopropyltriethoxysilane and 0.7ml of N,N-dimethylaniline, using a high-speed homogenizer Stir and mix evenly to obtain a low-viscosity asphalt pavement micro-crack quick repair material.

Abstract

The invention relates to an epoxy acrylate type low-viscosity rapid repairing material for microfractures of an asphalt pavement and a preparation method of the rapid repairing material. The preparation method comprises the steps of uniformly mixing epoxy resin, N,N-dimethylaniline, methyl methacrylate, methacrylonitrile butyl ester, asphalt and the like, reacting at 60-90 DEG C for 3-4 hours, cooling to the room temperature, adding benzoyl peroxide, an inorganic filler, gamma-aminopropyl triethoxysilane and N,N-dimethylaniline, stirring, and uniformly mixing, so as to obtain the rapid repairing material for the microfractures of the asphalt pavement. The performance of the prepared rapid repairing material can meet the requirements on dynamics, thermology and durability of the asphalt pavement, and the rapid repairing material can coordinate with a primary asphalt pavement; and meanwhile, the repairing operation construction is simple and convenient, the repairing time is controllable, and the influence to traffic flow is reduced. By utilizing a method for preparing epoxy methylacrylate resin by opening an epoxy ring by virtue of methylacrylic acid and epoxy resin, the problem that the initial viscosity of the repairing material is sensitive to pre-polymerization time is improved.

Description

technical field [0001] The invention belongs to the technical field of rapid repair of micro-cracks in asphalt pavement, and relates to an epoxy acrylate type low-viscosity asphalt pavement rapid repair material for micro-cracks and a preparation method. Background technique [0002] As a seamless continuous pavement, asphalt concrete pavement is widely used in the construction of high-grade highways because of its good mechanical properties, stable driving, low noise and no dust. However, due to the influence of the environment and vehicle loads on the asphalt concrete pavement during use, various early diseases, such as cracks, ruts and potholes, etc., gradually appear, among which cracks are the most common and most important form of disease, and micro cracks are the early development of pavement cracks state, if not controlled, will often lead to more serious and other damages. The current potting materials are generally only for wide cracks due to their high viscosity,...
