II. PAVEMENT ENGINEERING AND PAVING MATERIALS

2. FLEXIBLE PAVEMENT

A. ON GOING PROJECTS
5. Specification for Construction of Pavement of Haul Road for 280 Tonne Haulage Dumpers for Gevra Project
Date of Start:

September 2005
Central Road Research Institute, New Delhi (R)

 

Present Status and Progress
Field investigations and laboratory evaluation completed, secondary data/information collected
 
Findings/ Conclusions
Design and specifications for haul road pavement needed special approach since 260 T haulage trucks/dumpers use these roads in the project area. The existing pavement crust and subgrade along new alignment are examined and needed evaluation and data analysis carriedout for design. Available material properties, traffic and other data are also used.
 
Interim Conclusions
Flexible pavement design and specifications provided
 
Recommendations
The performance of road pavement may be monitored
