Asphalt/cement composite-based normal-temperature self-compacting asphalt concrete and preparation method thereof

The invention discloses asphalt/cement composite-based normal-temperature self-compacting asphalt concrete. The asphalt/cement composite-based normal-temperature self-compacting asphalt concrete comprises the following components in parts by weight: 10-20 parts of emulsified asphalt, 4-12 parts of cement, 40-73 parts of aggregate, 12-23 parts of mineral powder, 1-3 parts of a bonding agent and 1-5 parts of water. By optimizing the formula and grading composition of the asphalt concrete, the obtained concrete can be mixed and paved at normal temperature, can realize self-compaction (without being rolled by a compaction machine) after being paved, and shows the advantages of high early strength and the like; and the related preparation and construction methods are relatively simple, environment-friendly, low in energy consumption and suitable for popularization and application. 本发明公开了一种沥青/水泥复合基常温自密实沥青混凝土，各组分及其所占重量份数包括：乳化沥青10～20份，水泥4～12份，集料40～73份、矿粉12～23份，键合剂1～3份，水1～5份。本发明通过对沥青混凝土配方和级配组成进行优化，所得混凝土可进行常温拌和、摊铺，摊铺后能
