“For optimum utilization of the meager funds and prioritization of the development and maintenance works, it is of urgent necessity to introduce the Maintenance Management System both for pavement and bridges. This system has to be computer based and using Highway Design Model developed by WB updated to HDM-4.”

Report of the Committee on norms for maintenance of Roads in India, IRC-2001

Outcome of GIS based RMMSOutcome of GIS based RMMS

Developed RMMS Software with HDM-4 as core for managing Road Information Database Complete Data collection for 6000 km of PWD road networkMaintenance Intervention Strategy for PWD road networks was evolved.Central RMMS & GIS unit formed with in PWDData collection manual preparedRMMS Training was given to 200 engineers

Out come of the GIS based RMMSOut come of the GIS based RMMS

• Base Map of Kerala covering 27904 km of PWD roads prepared

• About 3000 Bridges identified and marked.

• Fully functional Central GIS unit with necessary hardware and software was established.

• Arc GIS at Central unit and Customized GIS at Divisions

• GIS awareness and training to around 300 PWD engineers

• Linked with RMMS data for visualization and analysis

Asset Preservation Concept Maintenance should be a regular process not a random event ( PBMC..?)Maintenance shall be preferably preventative Improvement of pavement strength by rehabilitation should be included in the maintenance strategy.Fund allocation should be based on ‘Higher Economic Return’ (Benefit Cost Ratio)

One of the key objectives in implementing an RMMS is to provide justification for budget, and to help direct limited funds towards those areas where the return on investment will be greatest.
