一种硅类天然矿物的断级配沥青混合料及其制备方法
摘要：
本发明涉及道路路面铺设材料，属于道路材料制造领域，尤其涉及一种硅类天然矿物的断级配沥青混合料及其制备方法。包括改性沥青、稳定剂和集料，所述的稳定剂采用硅类有机活性矿物，其中改性沥青的质量占集料质量的百分数为5.0%～6.0%；所述的稳定剂掺量为改性沥青质量的0.2%～0.4%。本发明混合料的配置方法包括如下步骤：1）将按改性沥青的质量占集料质量的百分数称量的改性沥青放入小型沥青拌合装置中加热后，将稳定剂缓慢倒入改性沥青中配制成沥青混合物；2）按级配的准备好集料，加热并输送到拌合楼；3）将步骤1）中搅拌好的沥青混合物按混合料的配比泵送至拌合楼中，经搅拌混合制备成沥青混合料。
摘要（英）：

The invention relates to a road pavement paving material, belongs to the road material manufacturing field, and especially relates to a silicon natural mineral asphalt mixture with gap gradation and a preparation method thereof. The asphalt mixture provided by the invention comprises modified asphalt, a stabilizing agent and an aggregate, wherein the stabilizing agent is made from silicon organic active mineral; the weight of the modified asphalt accounts for 5.0-6.0% the weight of the aggregate; and the mixing amount of the stabilizing agent accounts for 0.2-0.4% the weight of the modified asphalt. The preparation method of the mixture comprises the following steps of: 1) adding the modified asphalt which is weighed according to the weight of the aggregate into a small asphalt mixing device for heating, and slowly pouring the stabilizing agent into the modified asphalt to prepare the asphalt mixture; 2) heating the aggregate prepared according to gradation and conveying the aggregate to a mix plant; 3) pumping the stirred asphalt mixture obtained from Step 1) according to the ratio of the mixture to the mix plant, stirring and mixing to prepare the asphalt mixture.
