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 Patos crude oil regular decompression unit, customized Production, the penetration index is controlled at 45-55 (0.1mm).

[0027] Production process: Deep-draw and straight-distill Patos crude oil through a distillation unit to obtain customized matrix asphalt 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 extracted oil, a...

Abstract

The invention relates to a high-viscosity and high-elastic modified asphalt produced from Patuosi crude oil straight-run asphalt and a preparation method thereof. The high-viscosity and high-elastic modified asphalt comprises the raw materials: 85-90 parts by mass of matrix asphalt, 5-10 parts by mass of an SBS modifying agent, 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 and high-elastic modified asphalt has low cost, has the 60 DEG C viscosity of greater than 100000 Pa.s, is an excellent-performance asphalt binding material, can be applied to bridge deck pavement, drainage pavements and water permeable pavements, can effectively improve the durability of an asphalt mixture, and fully meets the use requirements of a drainage asphalt mixture; the blended asphalt mixture has excellent moisture damage resistance, rut resistance and flying resistance.

Description

technical field [0001] The invention discloses a high-viscosity and high-elasticity modified asphalt produced by Patos crude oil straight-run asphalt 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 elastic...
