A Portland cement for the bed of high-grade highway is prepared from cement clinker, mixture, gypsum, and additive. Its advantages are micro expansion, high antiflex cracking strength, toughness, and imperviousness, and low hydrous heat and alkali content. 本发明公开了一种专用于高等级公路稳定层的固基硅酸盐水泥；该水泥由28-35％的水泥熟料、50-65％的混合材，5-12％的石膏及少量水泥外加剂配制而成，具有微膨胀、高抗折强度、高韧性、低脆性、高抗渗性、低水化热、碱含量低、凝结时间适中等特性，经京珠高速公路试使用，完全克服了现有稳定层材料使用后所出现间断性裂纹等缺陷，提高了高等级工程的使用寿命。
