摘要
相较传统涂覆式TiO_2沥青路面尾气降解技术,掺入式TiO_2技术能够有效实现耐久性的显著提升,但其对沥青路面各项性能是否存在影响则有待验证。将TiO_2掺入橡胶沥青OGFC级配中,通过试验分析该技术对沥青胶结料、沥青混合料性能以及成型混合料尾气降解效果的影响,研究结果表明,掺入式TiO_2不会对OGFC各项性能造成负面影响,同时,总结得出掺入式TiO_2技术的三阶段尾气降解规律。
Compared with traditional method of coating type TiO2,mixed type TiO2is much better.It is necessary to confirm that whether the mixed type TiO2will be affect asphalt pavement performance.The paper mixed TiO2into rubber asphalt OGFC,and make experiments to study the influence to the performance of asphalt,mixture,and exhaust degradation effects.The study concludes that mixed type TiO2has no negative effects to OGFC,meanwhile,the exhaust degradation shows a law of three stages.
