Embodiment 1

[0020] The present invention also provides a preparation device for asphalt mixture, comprising a base 1, two vertical boards 2 correspondingly arranged are fixedly mounted on the upper surface of the base 1, and a rotating shaft 3 is rotatably mounted on the two vertical boards 2, And the two rotating shafts 3 are coaxially arranged, any one of the rotating shafts 3 is connected with a rotating drive module, a vertical barrel body 4 is fixed between the two rotating shafts 3, a top plate 5 is arranged above the barrel body 4, and the top plate 5 The upper part is rotatably equipped with a vertical shaft 6 coaxially arranged with the barrel body 4, and the bottom end of the vertical shaft 6 is fixedly connected with a stirring shaft 7 coaxially arranged therewith, and the surface of the vertical shaft 6 above the stirring shaft 7 is fixed along the circumferential direction Several crossbars 8 evenly distributed are installed, and an electric heating rod 9 parallel to the verti...

Embodiment 2

[0029] Example 3

[0030] An asphalt mixture, including matrix raw materials and asphalt additives, the formula of the raw materials by weight is as follows: 4 parts of matrix raw materials, 0.7 parts of asphalt additives.

[0031] The matrix raw materials are composed of asphalt, coarse aggregate, fine aggregate, mineral powder, polymer, and wood cellulose.

[0032] The mineral powder is limestone mineral powder. Limestone powder plays a filling role in asphalt mixture, the purpose is to reduce the void of asphalt concrete, sometimes called filler. Mineral powder and asphalt together form asphalt mortar, which improves the strength and stability of asphalt concrete. The amount of slag powder content is often expressed by the powder-oil ratio. The high-temperature rutting resistance of asphalt concrete is usually strong when the powder-oil ratio is large, and the small powder-oil ratio is beneficial to the low-temperature crack resistance of concrete.

[0033] The drive mod...

Abstract

The invention relates to the technical field of asphalt materials, in particular to an asphalt additive and an asphalt mixture containing the additive, and the asphalt additive is prepared from the following raw materials in parts by weight: 1-3 parts of castor oil, 0.5-1 part of ethylene polyamine, 1-2 parts of rosin and 2-2.5 parts of naphthenic acid. The asphalt mixture comprises a matrix raw material and an asphalt additive, and the formula of the asphalt mixture comprises the following raw materials in parts by weight: 3-4 parts of the matrix raw material and 0.5-0.7 part of the asphalt additive, the matrix raw materials comprise asphalt, coarse aggregate, fine aggregate, mineral powder, polymer and wood cellulose; selecting limestone mineral powder as the mineral powder; the polymer is selected from rubber powder; the low-temperature-resistant rubber has the advantages of good low-temperature resistance, strong adhesiveness and long service life.

Description

technical field [0001] The invention relates to the technical field of asphalt materials, in particular to an asphalt additive and an asphalt mixture containing the additive. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch: wherein, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries as well as paving roads. Asphalt mixture is...
