Bi-component modified asphalt cold-patch material and preparation method thereof
The invention belongs to the technical field of highway engineering, and particularly relates to a bi-component modified asphalt cold-patch material and a preparation method thereof. According to thebi-component modified asphalt cold-patch material, a mixture is cured in a chemical curing mode, so the early strength of the mixture is improved, the forming strength of the mixture is rapidly achieved, and the formed cold-patch asphalt mixture has the same or better water immersion and strength performance compared with a hot-mix asphalt mixture. The problems that conventional cold-patch asphaltmixtures are prone to falling off and upheaval and cannot be used in a large area are fundamentally solved, and the application scope of the bi-component modified asphalt cold-patch material is wide.
本发明属于公路工程技术领域，具体涉及一种双组分改性沥青冷补料及其制备方法。本发明的双组分改性沥青冷补料，是利用化学固化的方式来对混合料进行固化，提高其早期强度，并快速使其达到成型强度，使冷补沥青混合料成型后达到或者优于热拌沥青混合料的侵水及强度性能。从根本上解决冷补沥青混合料容易脱落、拥包、无法大面积使用的问题，并且应用领域广泛。
