  2. APT Steering Committee APT Steering Committee meeting - 5 April 2006 • Revision of HVS Strategic Plan • HVS programme: status report of projects • HVS future projects • HVSIA meeting

  3. APT Steering Committee Revision of HVS Strategic Plan 2004-2009 • New focus areas: • Structural pavement design methods • Sustainable development and the environment (old cold mix recycling) • Labour Intensive Construction (LIC) • Dissemination of information • Skills development / capacity building a Center of Excellence • Inclusion of “Benefits” section

  4. APT Steering Committee Focus Areas: • Sustainable Development and the Environment • Labour-Intensive Construction • Asphalt Performance • Provision of Low Volume Roads (including upgrading of unpaved roads) • Vehicle Pavement Interaction (including dynamic loads and contact stresses) • Concrete pavements • Structural Pavement Design methods

  5. APT Steering Committee HVS programme: status report of projects • Thin CR concrete pavement(sponsors:SANRAL & GDPTRW)– Concrete Pavements • Guidelines for bitumen stabilization with ETB & FB(sponsors: SABITA &GDPTRW) – Sustainable Development and the Environment • Forensic testing of AC Part 1&2 (sponsor:GDPTRW)-Asphalt Performance • SIM testing HVS and MMLS (sponsor: GDPTRW) -Vehicle Pavement Interaction

  6. HVS programme: status report of projects Ultra Thin CR concrete pavement • Testing of patented Danish mix completed • UP evaluating SA mix design • BKS involved in a dynamic FEM analysis • HVS testing of SA mix starting May 2006 • HVS testing completed October 2006

  7. HVS programme: status report of projects Guidelines for bitumen stabilization with ETB & FB • Inception report (phase 1) finalized in January 2006 • Phase 2 structural and mix design to be finished end of 2007

  8. 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 research Part 1&2 to be finalized by end of June 2006

  9. APT Steering Committee HVS future projects: • UTCR concrete pavements • HMA performance • Testing of “standard” mix • Testing of rut resistant mixes Starting time: October 2006
