Alkali-magnesium cement-based emulsified asphalt mortar for semi-flexible pavement as well as preparation method and application of alkali-magnesium cement-based emulsified asphalt mortar
The invention relates to the field of pavement materials, and particularly discloses alkali-magnesium cement-based emulsified asphalt mortar for a semi-flexible pavement as well as a preparation method and application of the alkali-magnesium cement-based emulsified asphalt mortar for the semi-flexible pavement, the alkali-magnesium cement-based emulsified asphalt mortar for the semi-flexible pavement is prepared from the following raw materials: an alkali-magnesium cement-based material, cationic emulsified asphalt, hydroxyethylidene diphosphonate, a filler and water; the alkali magnesium cement base material is prepared from the following components in parts by weight: 289.3 to 309.4 parts of magnesium oxide and 140.6 to 160.7 parts of magnesium sulfate; the weight ratio of the hydroxyethylidene diphosphonate to the magnesium oxide is (1.45-1.55): (289.3-309.4), the toughness of the alkali-magnesium cement-based emulsified asphalt semi-flexible pavement material is further improved, the alkali-magnesium cement-based emulsified asphalt semi-flexible pavement material is not prone to cracking, the service life of a road is further prolonged, and the safety performance of the road is further improved.
本发明涉及路面材料领域，具体公开了一种半柔性路面用碱镁水泥基乳化沥青砂浆及其制备方法和应用，所述半柔性路面用碱镁水泥基乳化沥青砂浆，由包括碱镁水泥基料、阳离子乳化沥青、羟基亚乙基二膦酸盐、填料和水的原料制成；所述碱镁水泥基料原料按重量份包括以下组分：氧化镁289.3‑309.4份，硫酸镁140.6‑160.7份；所述羟基亚乙基二膦酸盐用量和氧化镁用量的重量份比为(1.45‑1.55：289.3‑309.4)，本发明碱镁水泥基乳化沥青半柔性路面材料的韧性得到进一步改善，而且不易开裂，使道路使用寿命和安全性能得到进一步提高。
