HIGHWAY PLANNING, MANAGEMENT, PERFORMANCE EVALUATION AND INSTRUMENTATION
3.PAVEMENT PERFORMANCE
SUMMARY

Research work reported in the area of Pavement Performance mainly relates to study on optimum axle load of commercial vehicles for Indian Roads; Evaluation of Pavement Classification Number (PCN) of runway at Port Blair Airport. New projects initiated include Studies on application of coir geo-textiles for pavements, New concept and study of tolerance factors which results in determination of crust thickness after consolidation with regard to old as well as new pavements, Study on performance of a road constructed by oversize aggregates, Analytical study and review of road performance parameters/serviceability of roads made by different types of bitumen.

SALIENT POINTS FOR DISCUSSION
1. Optimum axle load of commercial vehicles for Indian Roads
2. Use of Coir Geo-textiles on pavements
3. Pavement performance characteristics using over-sized aggregates and different types of bituminous binders
