Active filler trials for in situ foamed bitumen stabilised pavements

Colin Leek, Hamid Nikraz and Amin Chegenizadeh


This report reviews the results of research undertaken into the performance of a road section stabilised with foamed bitumen incorporating different percentages of quick lime as active filler and compares with two other sections using Portland cement and another without active filler. An adjacent section with higher bitumen content is also compared.
