摘要
水泥稳定砂砾基层具有强度高、造价低廉及原材料来源广等优点,能够很好地适应当前黑龙江省的交通条件、自然条件和经济条件。针对齐齐哈尔当地的天然砂砾,进行室内无侧限抗压强度试验、水稳定性试验和抗冻性试验,分析水泥稳定砂砾的强度变化规律,得出适合当地基层施工的合理配比。
Cement stabilized gravel base has advantages of high strength, low cost and wide material som'ces, and adapts well to the natural, economic and traffic conditions in Heilongjiang Province. Based on local crude sand gravel in Qiqihar, indoor unconfined compression test, water stability test and frost resistance test were carried out to analyse strength change laws of cement stabilized sand gravel, and the reasonable proportion for bese course construction was concluded.
