Snow-melting and deicing epoxy asphalt mixture and preparation method thereof

Abstract

The invention discloses a snow-melting and deicing epoxy asphalt mixture and a preparation method thereof. The asphalt mixture comprises the following components in parts by mass: 0.7-2.6 parts of anepoxy asphalt component A epoxy resin, 0.2-1.9 parts of an epoxy asphalt component B curing agent, 2.9-4.5 parts of an epoxy asphalt component C matrix asphalt, 75-96 parts of aggregate and 1-15 partsof a snow melting agent. The snow-melting and deicing epoxy asphalt mixture disclosed by the invention has the beneficial effects that (1) the epoxy asphalt material body is high in strength, so thatthe prepared epoxy asphalt mixture can have high strength, can effectively resist a vehicle load effect and reduce rut diseases, can have long fatigue life so as to guarantee the long pavement structure of the epoxy asphalt mixture; and (2) the snow-melting agent cannot be directly exposed in the air in a large area under the wrapping of a stable epoxy asphalt cross-linked network structure, andcan slowly absorb moisture to achieve the purpose of slow release.

Description

technical field [0001] The invention relates to the technical field of road building materials, in particular to an epoxy asphalt mixture for melting snow and deicing and a preparation method thereof. Background technique [0002] Most areas in my country belong to seasonally frozen areas. In the cold winter, the snow on the road is compacted under the repeated action of temperature changes and vehicle loads, and thin ice is easily formed on the road surface, which greatly reduces the adhesion coefficient of the road surface. The braking stability and steering operation stability of the car will become worse, which often make the car easy to skid, run off, the braking distance will be significantly extended, and even the brakes will fail and the direction will be out of control, resulting in serious traffic accidents. In addition, when driving on icy and snowy roads, due to long-term strong light reflection stimulation, it is easy for the driver to suffer from eye pain, teari...

AI Technical Summary

Problems solved by technology

[0008] 1. Cause damage to the pavement structure and material properties, ranging from corroding the road surface to endangering the grassroots structure;

[0009] 2. The snow-melting agent used will saline the land, pollute the groundwater, and have adverse effects on the environment;

[0010] 3. The physical methods such as thermal melting of ice and snow will consume a lot of electricity, generate high economic costs, and cause a lot of energy consumption;

[0011] 4. The performance of the salt-storage self-melting snow-melting modified asphalt mixture is greatly affected by the snow-melting agent, which reduces the durability and service life of the road to a certain extent;

[0012] 5. The technology of encapsulating snowmelting agent in capsules or thermosetting shells is relatively difficult, the implementation steps are complicated, and the economic cost is high;

[0013] 6. With the increase of use time, the snow melting and deicing function of the formed self-melting snow pavement material decays rapidly, resulting in a short service life
