Registrations closing:  27th March 2023

AfPA and its members have been organising proficiency testing rounds since 2004. Apart from the benefits to individual laboratories in terms of improving consistency, the results have enable us to propose improvements to test methods nationally. The 2022/23 round will again be a national undertaking, providing all AfPA members and stakeholders the opportunity to be part of the industry drive to continually improve consistency and confidence in test results. Testing in this round will cover the following streams :

  • Stream 1 – Asphalt tests (asphalt mix sample will be provided)
  • Stream 2 – Binder extraction and testing (asphalt mix sample and binder sample will be provided)
  • Stream 3 – Coarse aggregate tests (coarse aggregate sample will be provided)
  • Stream 4 – Resilient modulus (asphalt mix sample will be provided)
  • Stream 5 – Wheel tracking (asphalt mix sample will be provided)
  • Stream 6 – Moisture sensitivity: Tensile strength ratio (TSR) (asphalt mix sample will be provided)
  • Stream 7 – Polymer Modified Binder test (binder samples will be provided)
  • Stream 8 – Fine Aggregate and Filler Samples (fine aggregate and filler sample will be provided)
