Shrinkage behaviour of cementitiously stabilised basaltic crushed rock mixed with fine grain soil
The aim of the project was to study the shrinkage behaviours of local stabilised pavement materials mixed with fine-grained soils to facilitate their effective use in road construction and rehabilitation. Laboratory tests were undertaken using one conventional cementitious binder and two binders comprising industrial waste products. Locally available basaltic crushed rocks and clay were used as host pavement material and fine-grained soil respectively. Shrinkage tests were carried out following guidelines developed for concrete in different drying conditions. This paper described effect of binder types and quantities on the shrinkage behaviour of stabilised materials. It was observed that inclusion of fine-grained soil has significant adverse effect on the shrinkage characteristics of stabilised pavement materials for cracking. One-dimensional drying resulted in slow rate of drying but higher final shrinkage than three-dimensional drying. (a) For the covering entry of this conference, please see ITRD abstract no. E211639.
