specific Embodiment approach 1

[0026] Specific embodiment one: this embodiment is a kind of filler that is applied to improving ice-asphalt pavement bonding effect in alpine region by weight and consists of 10 parts to 25 parts of low freezing point additives, 10 parts to 35 parts of zeolite, 10 parts to 40 parts Prepared from 1 part of pure water and 5 to 20 parts of water repellent;

[0027] The low freezing point additive is formate or acetate; the water repellent is organic silicon or polyurea.

[0028] The pure water refers to H without impurities 2 O, referred to as purified water or pure water, is pure, clean water that does not contain impurities or bacteria, such as organic pollutants, inorganic salts, any additives and various impurities. Water that meets the sanitary standards for drinking water is used as raw water.

[0029] The beneficial effect of this embodiment is that the anti-icing and anti-slipping of ice and snow pavement is the main problem faced by road traffic safety in seasonally fr...

specific Embodiment approach 2

[0031] Specific embodiment two: the difference between this embodiment and specific embodiment one is: a kind of filler that is applied to improve ice-asphalt pavement bonding effect in alpine regions consists of 25 parts of low freezing point additives, 30 parts of zeolite, 35 parts by weight Prepared with 1 part of purified water and 10 parts of water repellent. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0032] Specific embodiment three: a kind of preparation method of the filler that is applied to the alpine region to improve ice-asphalt pavement adhesion described in this embodiment is prepared according to the following steps:

[0033] 1. Weigh 10 to 25 parts of low-freezing point additives, 10 to 35 parts of zeolite, 10 to 40 parts of purified water and 5 to 20 parts of water repellent in parts by weight;

[0034] The low freezing point additive is formate or acetate; the water repellent is organic silicon or polyurea

[0035] 2. Grinding 10 to 35 parts of the weighed zeolite into a powder with a particle size of less than 0.6 mm to obtain zeolite powder;

[0036]3. Heat 10 to 40 parts of pure water weighed to a temperature of 60°C to 80°C, then add 10 to 25 parts of low-freezing point additives to the heated pure water, stir until completely dissolved, and obtain a low-freezing point aqueous solution;

[0037] 4. Add the zeolite powder into the low-freezing-point aqueous...

Abstract

The invention discloses padding used for overcoming the ice-asphalt road bonding effect in a high and cold region and a preparing method thereof, and relates to asphalt road padding and a preparing method thereof. The padding and the preparing method aims at solving the problems that the existing technology for processing ice and snow on an asphalt road in the high and cold region mainly depends on passive ice and snow removing aspects such as machines, manual work and chemical snow melting agents, and effective solving measures special for the ice-asphalt road bonding state are lacked. The padding is prepared by low-freezing-point additives, zeolite, purified water and water repellents. The preparing method includes the steps of 1, carrying out weighing; 2, preparing zeolite powder; 3, preparing a low-freezing-point water solution; 4, preparing low-freezing-point-substance-adsorbing ore particles; 5, preparing ore particles wrapped by the water repellents; 6, carrying out drying, and obtaining the padding used for overcoming the ice-asphalt road bonding effect in the high and cold region. The scheme is used for the padding used for overcoming the ice-asphalt road bonding effect in the high and cold region and the preparing method of the padding.

Description

technical field [0001] The invention relates to an asphalt pavement filler and a preparation method thereof. Background technique [0002] The research on ice and snow pavement anti-icing technology has always been a hot spot in the road engineering field. Existing research has explored a variety of road anti-icing technologies, which can be mainly divided into two categories: passive and active. The passive anti-icing method refers to relying on the outside world to act on the road surface to remove the ice layer on the road surface, so as to achieve the purpose of anti-skid. It consists of four methods: physical, chemical, artificial and mechanical. However, this method not only has poor deicing effect, but also cannot completely remove it. The ice layer on the road surface has little improvement on the frozen road surface, and it is very easy to cause adverse effects on the road and the surrounding environment during the application process; therefore, since the 1980s, usi...
