Asphalt concrete, preparation method and small-particle-size ultrathin overlay
A formula of asphalt concrete belongs to the field of road engineering. The asphalt concrete is prepared from the following components in 100 parts by weight: 4-8 parts of composite modified asphalt, 2-22 parts of 0-3mm broken stone, 65-85 parts of 3-6mm broken stone and 2-12 parts of mineral powder. The preparation method comprises the following steps of firstly, heating matrix asphalt to 170-180 DEG C, then adding a plasticizer and a styrene-butadiene-styrene block copolymer while stirring, and carrying out high-speed shearing swelling and stirring development, secondly, raising the temperature to 180-200 DEG C, adding the waste tire rubber particles, and then stirring at a constant temperature, and finally, cooling to 170-180 DEG C, adding the surfactant warm mixing agent, and uniformly stirring to obtain the composite modified asphalt material. The components are prepared according to the formula, the gravels, the composite modified asphalt and the mineral powder are sequentially placed in a stirring pot to be stirred, the prepared mixture is subjected to paving and rolling forming, and the asphalt concrete overlay is obtained.
一种沥青混凝土的配方，属于道路工程领域。以100重量份计包括：复合改性沥青4‑8，0‑3mm碎石2‑22，3‑6mm碎石65‑85，矿粉2‑12。首先，将基质沥青加热至170‑180℃，之后在搅拌下加入增塑剂及苯乙烯‑丁二烯‑苯乙烯嵌段共聚物，进行高速剪切溶胀及搅拌发育；其次，升温至180‑200℃，并加入废旧轮胎橡胶颗粒，之后进行恒温搅拌；最后，降温至170‑180℃，加入表面活性温拌剂，搅拌均匀，即得到所述的复合改性沥青材料。依据上述配方备好各个组分，并按照碎石、复合改性沥青、矿粉的顺序置于拌锅内搅拌，并将制备好的混合料进行摊铺、碾压成型，得到沥青混凝土罩面。
