AN INTRODUCTION TO IMPACT ROLLERS

Impact compaction in many forms is shown in this paper to have been used for centuries to densify earthworks but only recently has a towable impact roller been developed. This paper also sets out the requirements of an ideal impact roller and traces the design and development of prototypes through each stage to the machine which is economically and effectively fulfilling all the required functions. The results of field tests given show that compaction of collapsing sands and compaction in dry or semi-desert conditions are possible without excavation or increasing moisture content. Compaction in depth is achieved with impact rollers and the practicality of use as a construction tool on a wide range of soil types and as a proof roller is discussed. (TRRL)
