Developed under the auspices of the World Bank and managed by the World Road Association (PIARC), HDM-4 is a powerful decision-support system. It enables engineers, planners, and policymakers to predict road deterioration, estimate economic returns, and optimize funding allocations. What is HDM-4 Software?
The software uses a deterministic approach to input data regarding existing road conditions, traffic volume, and pavement composition to predict future pavement behavior, including pavement performance, rutting , and cracking . Core Modules and Applications hdm-4 software
At the programme level, HDM-4 helps users translate strategic objectives into concrete work programmes. Under constrained budgets, the software can prioritise road works across a network, ranking interventions by their economic return and ensuring that available funds are allocated to the projects that deliver the greatest value. This approach supports , helping users build programmes and budgets, prioritise interventions, and test long-term outcomes across a road network. Developed under the auspices of the World Bank
