Study on Different Alternative Maintenance Strategy for Flexible Pavement Using HDM
Keywords:
Highway Development and Management (HDM), Economic Internal Rate of Return (EIRR), Net Present Value (NPV)Abstract
Pavements which are left to weaken without promising support treatment are probably going to require major
rehabilitation and reconstruction much sooner than those which are legally kept up. Highway Development and
Management device, HDM-4 programming, created by the World Bank for worldwide applications is used for
recognizing an ideal upkeep technique for roadway pavements. The HDM-4 tool provides the deterministic approach in
data input and processing also utilizes data on existing road condition, traffic volume and crust composition to predict
road deterioration as per the road conditions in terms of any one variable such as cracks, roughness, pothole, raveling,
etc.,. HDM-4 simulates the best alternative that need to be applied based on Economic Internal Rate of Return (EIRR)
which consist Total Transportation Cost (TTC), Vehicle Operating Cost (VOC), roughness pattern for various
alternatives which are evaluated using HDM-4. HDM-4 is used for the present project analysis by using the existing data
of upgraded six lane road in order to select the best economic alternative from four different maintenance alternative
strategies. Optimum alternative is selected based on alternative which yields maximum Net Present Value /Cost Ration
and high Economic Internal Rate of Return (EIIR)
