Inception report (phase 1) finalized in January 2006

Phase 2 structural and mix design to be finished end of 2007

HVS programme: status report of projects

Forensic testing of AC Part 1&2 (HMA research) objectives:

Identify sections for detailed study Identify root causes of failures Identify characteristics of good performers Better understand HMA performance

characteristics Identify mix design aspects for further

researchPart 1&2 to be finalized by end of June 2006
