Problems solved by technology

[0007] At present, the price of imported and domestic high-viscosity modifiers on the market is relatively high, which makes the production cost unable to be reduced and increases the production investment cost of domestic road construction.
The use of waste rubber powder compounding has a certain effect on reducing the cost of production aids, but due to the high temperature production conditions, the exhaust gas generated has a greater impact on the surrounding environment, and the excessively high rubber powder content leads to poor storage stability of the product. Index Decays Too Fast

Embodiment Construction

[0025] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0026] Ingredients: High-viscosity and high-elasticity modified asphalt includes base asphalt and additives. The additives include SBS modification, extraction oil, extension agent and stabilizer. The base asphalt is straight-distilled and deep-drawn by Bachakro crude oil regular decompression unit, customized Chemical production, the penetration index is controlled at 45-55 (0.1mm).

[0027] Production process: Deep-draw and straight-distill Bachacro crude oil through a distillation unit to obtain customized matrix bitumen raw materials. The base asphalt is 88 parts, and then additives are added for modification, wherein the additive contains 7.5 parts by mass of the linear SBS modifier, 1.5 parts by mass of the e...

Abstract

The invention relates to high-viscosity high-elasticity modified asphalt produced from Bachaquero crude oil straight-run asphalt and a preparation method thereof. Raw materials include 85-90 parts by mass of matrix asphalt, 5-10 parts by mass of an SBS modifier, 1-2 parts by mass of extract oil, 2-4 parts by mass of a ductility improver and 0.1-0.3 part by mass of a stabilizer. The high-viscosity high-elasticity modified asphalt is low in cost, has the viscosity of more than 100000Pa.s at the temperature of 60 DEG C, is an asphalt binder with excellent performance and can be applied to bridge deck pavement, drainage road pavement and permeable pavement, the durability of an asphalt mixture can be effectively improved, the operating requirement of the drainage asphalt mixture can be completely met, and the blended asphalt mixture has excellent moisture damage resistance, rut resistance and scattering resistance.

Description

technical field [0001] The invention discloses a high-viscosity and high-elasticity modified asphalt produced by straight run asphalt of Bachacro crude oil and a preparation method thereof, belonging to the technical field of modified asphalt. Background technique [0002] In recent years, with the continuous improvement of my country's economic level, people's demand for travel quality has continued to increase, and the concept of "environmental friendliness" has become increasingly prominent in traffic construction. The drainage asphalt pavement with large gaps has high skid resistance, low noise, and prevents With the advantages of water drift and glare reduction, it becomes the best road surface with excellent road surface characteristics. [0003] Because the drainage asphalt pavement has the characteristics of a large amount of coarse aggregate and large porosity, the asphalt material is required to have good high temperature stability, low temperature flexibility and e...
