Anti-aging modified asphalt composition, and preparation method and application thereof
The invention relates to the technical field of road engineering,, and especially relates to an anti-aging modified asphalt composition, and a preparation method and application thereof. The modifiedasphalt composition comprises, by weight: 100 parts of asphalt; 5-10 parts of a thermoplastic elastomer; 2-6 parts of a tackifier; 0.1 to 1 part of a vulcanizing agent; 0.1-1 part of anti-aging agent.According to the anti-aging asphalt composition, the thermoplastic elastomer is introduced and is matched with the tackifier and other substances for use; therefore, the viscosity of the asphalt is improved; enough bonding force can be provided for aggregates; the anti-aging modified asphalt for the drainage pavement has the following advantages: the technical requirements of asphalt cement for the drainage pavement are met, meanwhile, the anti-aging modified asphalt for the drainage pavement has higher anti-aging performance, the problems of loosening, stripping and the like caused by agingin the use process of the drainage asphalt pavement are solved, and the service life of the drainage asphalt pavement is prolonged.
本发明涉及道路工程技术领域，特别是涉及一种抗老化改性沥青组合物及其制备方法和用途。所述改性沥青组合物的原料按重量份计，包括如下组分：沥青100份；热塑性弹性体5～10份；增粘剂2～6份；硫化剂0.1～1份；抗老化剂0.1～1份。所述抗老化沥青组合物中通过引入热塑性弹性体并将其与增粘剂等其他物质进行配合使用，从而提升了沥青的粘度，能为集料之间提供足够的粘结力，满足排水路面沥青胶结料的技术要求，同时本发明的排水路面用抗老化改性沥青又具有较高的抗老化性能，解决了排水沥青路面在使用过程中因老化造成的松散脱料等情况，延长排水沥青路面的使用寿命。
