HDM-Sentry - Example Analysis

HDM-Sentry - Example Analysis

Problem Outline: A section of road is constructed using gravel material and requires frequent maintenance to keep it in good condition. Its traffic levels are currently low, and are predicted to grow slowly over time. The road agency are considering an improved maintenance policy, or reconstructing the road to a bituminous road to reduce the frequent annual maintenance requirement.

Can this be economically justified?

  • The user can quickly change key inputs to determine the effect on the results, for instance, What would happen to the benefits if my traffic growth was ‘High’?
  • The indicative results can be used to justify the need for a more detailed analysis to be performed within HDM-4 to develop a case study for funding. The HDM-Sentry analysis can be used as the staring point for this analysis.
