A CRITICAL REVIEW OF INNOVATIVE RURAL ROAD CONSTRUCTION TECHNIQUES AND THEIR IMPACTS
HISTORY
INDIAN GOVERNMENT HAS PUT FORWARD MANY PLANS TO IMPROVE RURAL ROADS IN 11TH FIVE YEAR PLAN.
LACK OF KNOWLEDGE ABOUT GROUND IMPROVEMENT TECHNIQUES.
NEED FOR FREQUENT REPAIR.
DESIGN
Based on the CBR value of soil sub- grade.
Based on 10 years projected cumulative traffic with an assumed 6% traffic growth per year.
GROUND IMPROVEMENT TECHNIQUES
soil stabilization
Stabilization with lime
Stabilization with cement
Stabilization with combination of lime and cement
Industrial by products
Fly ash for the construction of embankments of sub-base and base-courses.
Steel and copper slags for the construction of sub-base and base-courses
Marble dust in sub- base and sub-grade
CONCLUSION
Groud improvement techniques through lime ,cement industrial products such as fly ash steel copper slags marbledust rice husk etc.
Innovations in ground improvement through Fujibeton ,Terrazyme,Renolith etc.
Alternative technologies through Jute Geo-textile,Flexible concrete pavement, use of waste plastic blended bitumen.
