Date of Start:

October 2005
(i) Central Road Research Institute, New Delhi (R, I)
(ii) M/s Consolidated Transportation Networks Limited, Mumbai (S)

 

Scope and Objectives

The project has been taken up with the aim (i) to study the adequacy or otherwise of the maintenance provisions / inputs planned in the concession agreement for maintaining the assets under BOT scheme and (ii) to recommend modifications in maintenance requirements in case the provisions stipulated in the concession agreements fall short of requirements to attain the specified serviceability level at the end of concession agreement.

The scope of study includes the following:

Benkelman Beam deflection studies at selected locations
Axle loads survey at one location
Traffic volume surveys at one or two locations
Roughness measurements using duly calibrated Fifth Wheel Bump Integrator
Visual assessment of pavement surface condition in terms of surface distress
 
Methodology
Field studies as stated above have been conducted and needed data collected. The data collected will be analysed through HDM-4 software to study/evaluate the likely performance of road as per future projected traffic loading conditions under planned / defined maintenance inputs. Findings emerging out of the study would be used in checking the adequacy of maintenance provisions / inputs planned in the concession agreement for maintaining the assets as per pre-determined requirements stipulated in the contract agreement. The results would also enable the client to take corrective measures in case maintenance inputs planned are found to be deficient during the concession period.
 
Significance/Utilization Potential
Results obtained using HDM-4 tools can be used towards development of optimal pavement maintenance strategies.
 
Recommendations
Many more such road projects being operated under BOT scheme need to be taken up to evolve a rational policy for arriving at the appropriate maintenance provisions under a given concession agreement keeping in view the traffic and environmental conditions.
