A kind of building stones surface property improves system and method
Technical field
The present invention relates to a kind of building stones surface property and improve system and method, especially a kind of large construction field building stones surface property improves system and method, belongs to road engineering field of mechanical technique.
Background technology
At present, must meet multinomial material property requirement for the building stones of road construction.But, because the single index of some building stones is defective, even if cause other performance index excellences of such building stones also cannot be applied, and then to remove the complete satisfactory building stones of farther regional procurement.This has caused building stones price high, and haul distance increases, and causes the building stones of some type are depended on unduly and exploited.Not only increase construction cost, but also because overexploitation has produced environmental disruption.For example, although acid or neutral building stones have good mechanical property and technical characterstic, but due to poor with the adhesive capacity of bituminous material, cannot meet the design requirements of corresponding bituminous pavement upper layer starting material, can limit to some extent in actual applications, and cannot realize the principle that road construction " is gathered materials on the spot ".In certain areas, can meet the high-quality alkalescence top layer building stones resource of bituminous pavement service requirements due to long-term exploitation, be on the verge of scarcity, be following inevitable development trend so use acid stone.Use acid stone will take in principle antistripping measure to make pitch and acid stone tight adhesion.Traditional antistripping measure is to add antistripping agent in pitch, as lime, and polyamide polymers etc.But the adding technology of traditional antistripping agent lacks specific aim, mainly adds in pitch, not directly for building stones pitch interface one by one, cause antistripping agent composition to fail to bring into play completely effect.Therefore, directly the function of surface of building stones is carried out to modification, be considered to improve effective way and the important development direction of asphalt overall performance.No matter use acid or alkaline building stones, can improve integral working and the surface chemical property of asphalt for building stones modifying surface comprehensively, after making the adhesive capacity of building stones and pitch reach national regulation to require, can set it as high-grade bituminous highway upper layer building stones, reduce modifying asphalt production link, reduce costs, there is great use value.
Except described in above-mentioned example to building stones modifying surface to strengthen the adhesive capacity of itself and bituminous material, the also properties-correcting agent of replaceable other type, to improve the adhesive capacity of building stones and other materials, or improve other performances (as waterproof, anticorrosive, shock resistance, radioprotective etc.) of building stones.Building stones process for modifying surface can be applied in multiple occasion, meets different demands, has very large development and application prospect.
While at the construction field (site) improved performance processing being carried out in building stones surface, the continuity (mainly referring to the continuity that building stones are carried) of system operation is most important.Therefore, in order to improve efficiency and the degree of uniformity of building stones surface modification, ensure the continuity that building stones are carried simultaneously, design a kind of building stones surface property that is specifically designed to working-yard and improve system and method and just seem particularly necessary.
