水泥作为常用的活性添加剂对泡沫沥青冷再生混合料有着重要的作用，水泥的用量会直接影响泡沫沥青冷再生混合料的性能。文章通过室内试验设计了含有不同剂量水泥的泡沫沥青冷再生混合料，并对混合料进行劈裂、车辙和低温弯曲试验，评价水泥对泡沫沥青冷再生混合料的影响。结果表明：水泥和沥青在泡沫沥青混合料中共同发挥胶结料作用，水泥剂量超过1.0%时，水泥形成的胶结强度大于沥青形成的胶结强度；水泥剂量为1.0%~1.5%时，泡沫沥青冷再生混合料泡沫沥青冷再生混合料整体性能较优，满足作为路面基层或中下面层的使用要求；水泥剂量大于2%时，混合料低温性能降低。

It is of great importance to explore the influence of cement on foamed asphalt cold recycled mixture for applying foamed asphalt cold recycled mixture in engineering. Effect evaluation of cement on foamed asphalt cold recycled mixtures was investigated in this paper. Foamed asphalt cold recycled mixtures were designed with cement or not and pavement performance tests were carried. Tests results show that cement and asphalt play roles of binders for foamed asphalt cold recycled mixtures and the bonding strength of cement is greater than that of asphalt when cement dosage is more than 1 . 0%. Foamed asphalt cold recycled mixtures has a better overall performance with cement controlled between 1 . 0% and 1 . 5% and the low temperature crack resistance of foamed asphalt cold recycled mixtures reduce with more than 2% cement.
