High-performance foamed asphalt in-situ cold recycling mixture
A high-performance foamed asphalt in-situ cold recycling mixture comprises the following raw materials: a first group of materials and a second group of materials, and the first group of materials comprises the following components in parts by weight: 15-20 parts of new aggregate, 1.5-2.0 parts of cement and 78-85 parts of asphalt mixture reclaimed material; the second group of materials comprises foamed asphalt and mixing water, the foamed asphalt is 1.5-3.0 parts by weight, and the addition amount of the mixing water enables the water content of the final regenerated mixture to be 3.6%-7.3%; the synthetic gradation determined by the asphalt mixture reclaimed material gradation, the new aggregate gradation and the cement gradation should meet the condition that the passing rate of 0.075 mm is not lower than 3.0%; and the recycled material gradation of the extracted asphalt mixture and the synthetic gradation composed of the new aggregate should meet the requirement that the passing rate of 4.75 mm is not higher than 45%. The cold recycling mixture has the advantages of being suitable for the surface layer of the heavy traffic asphalt pavement and capable of achieving synchronous paving.
一种高性能泡沫沥青就地冷再生混合料，该混合料的原料包括第一组物料和第二组物料，所述的第一组物料包括：新集料15‑20重量份，水泥1.5‑2.0重量份，沥青混合料回收料78‑85重量份；所述的第二组物料包括：泡沫沥青，拌和用水，所述的泡沫沥青为1.5‑3.0重量份，所述的拌和用水添加量为使得最终再生混合料的含水率为3.6％～7.3％；所述的沥青混合料回收料级配、新集料级配和水泥级配确定的合成级配应满足0.075mm的通过率不低于3.0％；抽提后的沥青混合料回收料级配与新集料组成的合成级配应满足4.75mm的通过率不高于45％。具有适应于重载交通沥青路面面层，并且能够实现同步摊铺的优点。
