Benefits of technology

This patented technology describes an improved method called HPES (High Performance Evaluated Softening Exchanger) used during road construction or repair processes. It involves mixing eight different types of polymer together by adding ethyneoxypropyltrimetanon trisodimethysisilicate hydride onto naphtha solvent containing olefin compounds. By doing this, they create strong bindings on both pitch and gravel surfaces while maintaining their original physical characteristics like flexibility and durability. These modified solutions have superior performance compared to existing products due to increased contact area and reduced surface tendency caused by void spaces within porous aggregates.

Problems solved by technology

Technological Problem addressed in this patented text relates to improves the adhesion and durable property of bituminous materials used in paving applications like roads. Current methods involve mixing them together before use, allowing any impurities within those mixtures to affect their behavior. However, current techniques have limitations because they require long periods of heat treatment and cooling cycles until complete recovery occurs.

Abstract

The invention relates to a preparation method of a high-permeability asphalt recycling agent and belongs to the technical field of preparation of engineering materials. According to the preparation method, isooctanol polyoxyethylene ether is heated and then dimethyldichlorosilane is added, so that a coupling channel is established between an organic silicon structure and the isooctanol polyoxyethylene ether; biological raw materials including bagasse, pork livers, rice straw, peanut oil and the like are subjected to high-temperature and high-pressure extraction under the protection of nitrogengas, so as to obtain organic components in the biological raw materials; functional groups can form a covalent bond, a hydrogen bond and intermolecular interaction force adsorption with other particles; bamboo sheets are also put into a sodium hydroxide solution and are immersed at high temperature; then sodium sulfite and formaldehyde are blended, so that bamboo fibers are subjected to sulfonation reaction and hydroxymethylation reaction; two types of hydrophilic functional groups are introduced and lignosulfonate extracted from the bamboo fibers can be dispersed into the asphalt recycling agent better; the mechanical properties of the asphalt are reinforced through the excellent mechanical properties of the bamboo fibers; the high-permeability asphalt recycling agent has a wide application prospect.
