ENGINEERING PROPERTIES OF SOIL STABILIZED BY FERRUM LIME AND USED FOR THE APPLICATION OF ROAD BASE.

In this paper, the behaviour of soil stabilised by ferrum lime, a mixture composed of ferric oxide (Fe2O3) and hydrated lime (Ca(OH)2), is investigated in order to assess the engineering properties of the stabilised soil for its application to road construction. The aptitude of the ferrum-lime stabilised soil as road base material is evaluated according to the static compressive, static flexural, and dynamic resilient properties of materials obtained from laboratory tests. The ferric oxide promotes an increase in both compressive strength and the stiffness of the stabilised soil. Resilient modulus Mr, a parameter expressing the material behaviour under dynamic cyclic loading, depends on the deviator stress and the mean principal stress. Under lower deviator stress and mean principal stress conditions, the Mr of the ferrum-lime stabilised soil has a higher value than that of the hydrated-lime stabilised soil. The difference in resilient modulus Mr between the two types of stabilised soils may not be distinct with increases in the deviator stress and the mean principal stress. In addition, the dependence of resilient modulus Mr on the static strength of the ferrum-lime stabilised soil can be observed. According to test results, ferric oxide can improve the durability of pavement when it is used as a stabiliser for lime stabilised soil.
