摘要
针对高液限粘土路用性能的局限性,结合国道207线改建工程,采用了掺加水泥或砂石料改良高液限粘土,现场试验结果表明,掺加3%或4%水泥改良后的高液限粘土可用于路基不同压实区的填筑;采用掺加砂石料改良高液限粘土时,则须考虑高液限粘土的天然含水量,并使改性后的高液限粘土含水量趋于最佳含水量。
This paper recommends method that dash with cement and gravel to the high liquid limit of clay that used in 207 national highway. The field experimentation indicates that the high liquid limit of clay dash with 3% or 4% cement is used in different high filling culvert. The field experimentation suggests that we should consider the nature water content of the high liquid limit of clay and make sure the water content tend to best water content when dash with gravel to it.
