Early-strength high-viscosity additive, drainage asphalt mixture and preparation method thereof
The invention belongs to the technical field of asphalt mixture additives, and particularly relates to an early-strength high-viscosity additive, a drainage asphalt mixture and a preparation method thereof. The early-strength high-viscosity additive comprises the following components in parts by weight: 35-50 parts of rubber, 45-60 parts of an early-strength resin material and 3-8 parts of slakedlime. According to the high-viscosity additive, a drainage asphalt mixture test piece can be placed at room temperature for 12 hours, the Marshall stability is greater than 7KN, the standard scattering loss is less than 10%, the dynamic stability is greater than 8000 times/mm, and the early strength of the drainage asphalt mixture is significantly improved, so that the traffic maintenance time ofthe drainage asphalt pavement is reduced to 12h from 48h or above, and the problems of construction cost, traffic interference caused by drainage asphalt pavement construction and the like can be effectively reduced.
本发明属于沥青混合料外加剂技术领域，具体涉及一种早强型高粘度添加剂、排水沥青混合料及其制备方法。以重量份计，所述早强型高粘度添加剂包括以下组分：橡胶35～50份、早强型树脂材料45～60份，消石灰3～8份。该高粘度添加剂可使排水沥青混合料试件在室温放置12h后，马歇尔稳定度大于7KN，标准飞散损失小于10％，动稳定度大于8000次/mm，显著提高了排水沥青混合料的早期强度，从而将排水沥青路面通车养生时间由48h以上减小至12h，能有效减少施工成本以及排水沥青路面施工造成的交通干扰等问题。
