掺加适量水泥替代矿粉提高沥青凝土性能,在国内研究很少。文中通过水泥替代石灰石质矿粉对沥青胶浆软化点、针入度和抗老化性能影响的研究,发现掺加适量的水泥可显著提高沥青混凝土的温度稳定性和水稳性。
Addition of appropriate amount of cement instead of slag to improve the performance of asphalt concrete, few studies in China. In this paper, cement softening point, penetration degree and anti-aging performance of asphalt mortar are studied by cement instead of limestone. It is found that adding appropriate amount of cement can obviously improve the temperature stability and water stability of asphalt concrete.
