| Abstract: | Lime-ash is the mixture of lime and coal ash with the properties of good intensity, integrity and water resistance. To use lime-ash in expressway base construction can effectively save the cost and be of some advantages in economic and social benefits. This paper, based on engineering example, through ana-lyzing the application advantages of lime-ash subbase in engineering, systematically discusses the appli-cation of lime-ash subbase in expressway construction and the quality controlling measures. |
