Embodiment Construction

[0019] Take the severe saline-alkali soil with a pH of 9.5 and dry it, collect the dry matter and ball mill it, collect the ball mill powder and put it in a crucible, put the crucible in a muffle furnace, heat up to 1650-1700°C at 10°C / min, keep warm and melt After 25 to 30 minutes, collect the molten liquid and draw it, control the diameter of the molten drawing to 0.5 to 0.8 mm, collect the drawn fiber and place it at 650 to 700 ° C for annealing treatment for 3 to 5 hours, and then let it stand to cool to room temperature to obtain the matrix salt storage Fiber; count parts by weight, weigh 5-10 parts of polydimethylsiloxane, 45-50 parts of N, N-dimethylformamide, and 10-16 parts of matrix salt-storing fiber and place them in a mortar , grind and disperse and collect the mixed slurry, dry the mixed slurry at 130-140°C for 3-5 hours, obtain the dried product and grind it, and pass through a 200-mesh sieve to obtain modified fiber particles; according to the mass ratio of 1:10...

Abstract

The invention relates to a preparation method of a high bonding type salt storage asphalt pavement material and belongs to the technical field of building materials. According to the technical scheme,heavy saline-alkali soil is adopted as a raw material, and subjected to high-temperature calcining and wire drawing in fusion; by a high-concentration saline-alkali material in the saline-alkali soil, wires are drawn and fibers are collected, and by full bonding with resin particles, the bonding property between the material and resin is effectively improved; by excellent bonding property betweenmixed resin and asphalt, the bonding strength of the material is further improved; in the technical scheme, the saline-alkali soil is adopted as a modifying raw material, organic matters carbonized by high temperature are mostly decomposed, a small part of the organic matters form porous carbide and are loaded to the surface of a fiber material, and by excellent structural property of the surfaceof the carbide, the bonding strength between the material and the resin is improved, so that the bonding property and the mechanical strength of the compound asphalt material are further improved.

Description

technical field [0001] The invention relates to a preparation method of a high-combination salt-storage asphalt pavement material, which belongs to the technical field of building materials. Background technique [0002] Snow and ice on the road will greatly reduce the friction coefficient of the road surface, that is, the grip force of the tires on the road surface will be greatly reduced, which will cause traffic accidents due to untimely braking. The traditional snow and ice removal in our country will cause damage to the environment. Chlorine salt is usually used to eliminate snow and ice on the road. However, a large amount of salt may pollute the surrounding water, soil and vegetation. In addition, if it is used for bridge decks, the steel structure will be severely corroded, and it will also weaken the bond between the asphalt and aggregate, thereby affecting the service life of the asphalt concrete pavement. [0003] Due to the good snow melting and ice suppression ...
