PlanningJain : Development of Pavement Deterioration Models (HDM4) in India

Jain : Development of Pavement Deterioration Models (HDM4) in India

Pavement deterioration Model to help predict condition of pavement at future date

Determine or plan strategy Adjust World Bank’s HDM-4 Model to India specific

conditions Calibrate to low volume roads Window methodology Observe different ages of roads of similar conditions Decide optimal type and timing of remedial actions

Design• Lerfald: Development of a new asphalt mix design

system in Norway

Lerfald: Development of a new asphalt mix design system in Norway

Norwegian research project 1998-2004 Develop performance based specifications and new mix

design procedures New binder selection system for mix design based on local

climate and traffic New methods to measure E modulus and deformation

properties using NAT and Gyratory compactor Busy gathering information before giving to practice
