Economic Analysis of Road Pavements

At HHO, we believe that our clients need to be well informed about all road construction and rehabilitation options, and which options present the best investment of available funds.

We have a wealth of experience in road pavement design and utilise the HDM4 software package to assist with the economic evaluation, during the planning and investment decision phases of a highway project. The HDM4 software offers us the ability to advise on the life cycle cost management of a highway project.

  • Pavement structural performance and deterioration
  • Maintenance and rehabilitation intervention costs
  • Road user costs and benefits
  • Economic comparison of project alternatives

HDM4 has been successfully used by HHO to advise a range of clients which include SANRAL, Provincial and Local Road Authorities and Private Developers.
