Embodiment 3

[0055] A method for preparing warm-mix asphalt concrete for energy saving and consumption reduction, comprising the following steps:

[0056] S1: Prepare warm mix asphalt mixture according to the proportion of ingredients, and heat it for standby;

[0057] S2: Put the mineral material and rubber particles into the asphalt mixing plant for dry mixing;

[0058] S3: Then add the warm-mix asphalt mixture prepared by heating and stir.

[0059] In S1, the preparation method of warm mix asphalt mixture is as follows: after heating the base asphalt, add expanded graphite and stir and mix; then take epoxy soybean oil and polymer to stir and dissolve evenly; then mix the two, and finally add basalt fiber , surfactant, fatty acid to obtain warm mix asphalt mixture.

Abstract

The invention discloses a warm-mix asphalt concrete for energy saving and consumption reduction, which comprises the following raw materials and their parts by weight: 75-92 parts of mineral material, 7-10 parts of warm-mix asphalt mixture, and 15-30 parts of rubber particles; The warm asphalt mixture includes the following components by weight: 70-90 parts of base asphalt, 2-5 parts of polymer, 0.5-2 parts of surfactant, 2-5 parts of fatty acid, and 1-2 parts of basalt fiber; After the warm mix technology, the harmful gases emitted by the asphalt mixture during the mixing production process can be greatly reduced, and the emissions of carbon dioxide and nitrogen oxide gases are reduced by 60.0%-72.6%; the warm mix asphalt mixture can be compared with the corresponding hot mix asphalt The material can save energy by 22.9%-30.2%; it can really realize the good performance of the mixture, and at the same time can reduce the cost of preparation and use, so as to achieve the purpose of saving energy and reducing consumption, which is beneficial to environmental protection.

Description

technical field [0001] The invention relates to the field of warm-mix asphalt, in particular to a warm-mix asphalt concrete for energy saving and consumption reduction. Background technique [0002] Hot mix refers to a construction method in which a certain proportion of aggregate and asphalt are heated to (150-180°C) temperature respectively, and then mixed evenly; although this construction method makes all the properties of asphalt meet the construction requirements, it improves the construction efficiency. The quality and the convenience of construction, but the heating temperature is high during the hot mixing process, which not only consumes a lot of thermal energy, but also discharges a lot of asphalt mixture during the mixing and paving process. Harmful gases such as carbon dioxide, sulfur dioxide, nitrogen oxides, and asphalt smoke produce a large amount of dust at the same time; seriously affect the surrounding air quality and cause environmental pollution. In addi...
