GOVERNMENT OF INDIA MINISTRY OF RAILWAYS STUDY REPORT ON COMPACTION EQUIPMENTS AND CONSTRUCTION MACHINERY REPORT No. GE- R-76 SEPTEMBER - 2005 Geotechnical Engineering Directorate Research Designs & Standards Organization Manak Nagar, Lucknow-11 CONTENTS DESCRIPTION PAGE NO. 1. INTRODUCTION 1 2. SCOPE 1 3. IMPORTANCE OF ADEQUATE COMPACTION OF EARTHWORK 1 4. FACTORS AFFECTING COMPACTION IN THE FIELD 1 5. FIELD COMPACTION TRIALS 3 6. TYPE OF COMPACTING EQUIPMENTS 3 7. CONSTRUCTION MACHINERY 21 8. CONCLUSION 29 9. REFERENCES 29 1 INTRODUCTION: In earlier days, embankment design and construction were not given adequate attention.

Proper control of moisture content in soil is necessary for achieving desired density. Maximum density with minimum compacting effort can be achieved by compaction of soil near its OMC (Optimum Moisture Content). If natural moisture content of the soil is less than OMC,
