| Abstract: | The expansive soil is a kind of particular soil. Its characteristics are being expanding when it is watered and shrinking when it is dried. Its reciprocating deformation will impact the service function of road in future and causes destruction. Through discussing its property, geological characteristics and treatment methods, its destructive mechanism is expatiated on, which deserves reference. |
