HDM-4 analysis of maintenance alternatives for the Malawi road network.
A Pavement Management System (PMS) was implemented in Malawi in 2006 by TRL. The PMS comprises two components; a centralised road database entitled Road Data Manager (RDM) and the economic analytical tool, the Highway Development and Management tool (HDM-4). Road surveys comprising ordnance, inventory, condition, traffic counts, pavement layer thickness and strengths were conducted in 2006 and the data entered in RDM. Also in 2006 HDM-4 was configured and adapted for Malawi, and personnel from the Roads Authority (RA) were trained in the use of HDM-4. This resulted in the Malawi PMS being fully implemented in 2006. This report is based on a visit undertaken by TRL in March 2008 to update the Malawi Pavement Management System and then to use the PMS to examine various maintenance alternatives for managing the Malawi road network.
