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.
