| 摘 要： | 通过对高液限红粘土掺加不同比例的砂砾、石灰、粉煤灰、二灰、水泥及“康耐”改良剂等进行液限、塑限、CBR等试验,研究红粘土的路用性能改良效果,认为本工程红粘土惰性较强,提出掺加30%的砂砾是最有效、最经济的改良措施。

| Abstract: | According to the tests of liquid limit,plastic limit and CBR to different amount of gravel-improved soil,lime-improved soil,lime-flyash-improved soil,cement-improved soil and CON-AID soil,the road properties of improved red clay are studied.Because the red clay in the engineering has more stronger inertia,it is proposed that adding 30% gravel is the most effective and the most economical improvement measure. |
