Tackifying polyester particles, slightly alkaline modified asphalt, preparation method and application of tackifying polyester particles and slightly alkaline modified asphalt in drainage type ultra-thin overlay
The invention belongs to the technical field of wearing layers, and particularly relates to tackifying polyester particles and slightly alkaline modified asphalt as well as a preparation method and application thereof in a drainage type ultrathin overlay. The invention provides an ultrathin wearing layer which can be used for an ultrathin condition (2cm and below) and can play a drainage role, so that the thickness of a water film can be reduced to 1mm within 30min under the conditions that water is not accumulated on a pavement in a short time, the precipitation is 30mm (in 24h) and the flatness of a 3m ruler method is not more than 5mm, and the ultrathin wearing layer has good drainage, sound absorption and noise reduction effects. The wearing layer is very thin, so that the pavement elevation does not need to be adjusted, and the wearing layer can directly cover the original road surface and can be used as a drainage pavement.
本发明属于磨耗层技术领域，具体涉及增粘聚酯颗粒和偏碱性的改性沥青及制备方法和在排水型的超薄罩面中的应用。本发明提供了一种可用于超薄情况（2cm及以下），且可以起到排水作用的超薄磨耗层，使得路面在短期内不积水，降水量30毫米（24h计）情况下，3m直尺法平整度在不超过5mm时，30min内水膜厚度可降至1mm，具有很好的排水和吸声降噪效果。磨耗层很薄，是可以使得路面标高不用调整，可以直接覆盖在原路表，且可以作为排水路面使用。
