Normal-temperature mixed asphalt mortar and integrated semi-flexible pavement material
The invention relates to normal-temperature mixed asphalt mortar. The normal-temperature mixed asphalt mortar comprises mixed asphalt and cement mortar, the mixed asphalt and the cement mortar are prepared by respectively preparing and then uniformly mixing and stirring; the mixed asphalt is reaction type normal temperature-emulsified asphalt obtained by mixing reaction type normal temperature asphalt and emulsified asphalt, and the mixed asphalt contains a defoaming agent; the cement mortar comprises Portland cement, water, silica fume and an additive; the reaction type normal-temperature asphalt is prepared by adding a reaction type liquefying agent and a modifier water-borne epoxy resin emulsion into matrix asphalt in a flowing state and carrying out shear mixing. The mixed asphalt has better low-temperature performance, the pavement material for integrated semi-flexible pavement construction prepared from the mixed asphalt and the aggregate such as RAP can be mixed and paved at normal temperature or low temperature, the advantages of a traditional pouring type semi-flexible pavement are reserved, the low-temperature crack resistance of the semi-flexible pavement is improved, heating is not needed in the whole process, and the pavement material can be applied to the construction of an integrated semi-flexible pavement. The environment is protected; and the pavement material cost is reduced.
本发明涉及一种常温混合沥青砂浆，其包括：混合沥青和水泥砂浆；所述混合沥青和水泥砂浆为分别制备完成后，再混合拌匀制得；混合沥青是由反应型常温沥青与乳化沥青混合得到的反应型常温‑乳化沥青，混合沥青中含有消泡剂；水泥砂浆包含硅酸盐水泥、水、硅灰和外加剂；反应型常温沥青为向呈流动态的基质沥青中添加反应型液化剂和改性剂水性环氧树脂乳液并剪切混合制得。混合沥青具有更优的低温性能，利用该混合沥青和RAP等集料制得一体式半柔性路面施工用路面材料，可常温或低温拌和及摊铺，保留了传统灌注式半柔性路面的优点，改善了半柔性路面低温抗裂能力，全程无需加热，保护环境并降低路面材料成本。
