Direct-vat set tackifying regeneration modifier as well as preparation and application methods thereof
The invention relates to a direct-vat set tackifying regeneration modifier and preparation and application methods thereof, and belongs to the field of road asphalt mixtures. The direct-vat set tackifying regeneration modifier is prepared by uniformly mixing the components in percentage by mass: 5-26.7% of bio-oil, 4-5% of stabilizer, 1-5% of modified tackifying liquid, 2.5-20% of mixed light oil,6.7-33.3% of an SBS modifier, 6.7-41.7% of an SIS modifier and 6.7-41.7% of an SBR modifier, wherein the sum of the mass percentages of all the components is 100%. The preparation method comprises the steps: 1, preparing an efficient asphalt regenerant; 2, preparing a direct vat set tackifying modifier mixture; and 3, mixing the prepared efficient asphalt regenerant and the prepared direct vat set tackifying modifier mixture according to a mass ratio to obtain the direct-vat set tackifying regeneration modifier. The direct-vat set tackifying regeneration modifier prepared by the method is applied to a large-proportion regenerated high-performance asphalt mixture, and the asphalt mixture with excellent properties can be obtained.
一种直投式增粘再生改性剂及其制备和应用方法，属于道路沥青混合料领域，按质量百分比5～26.7％的生物油，4～5％的稳定剂，1～5％的改性增粘液，2.5～20％混合轻质油，6.7～33.3％的SBS改性剂，6.7～41.7％的SIS改性剂，6.7～41.7％的SBR改性剂均匀混合而成，且各组份的质量百分比之和为100％。其制备方法包括：1、制备高效沥青再生剂；2、制备直投式增粘改性剂混合物；3、将制备得到的高效沥青再生剂和直投式增粘改性剂混合物按照质量比混合得到直投式增粘再生改性剂。本发明方法制备的直投式增粘再生改性剂，应用于大比例再生高性能沥青混合料，可以得到各项性能优良的沥青混合料。
