• Abstract:
  Several methods are available to determine aggregate characteristics, but their relationship to field performance, aggregate structure in HMA, and traffic loading needs to be further investigated and defined. Current laboratory protocols do not correlate well with aggregate abrasion, toughness, and strength requirements during handling, construction, and service. Specifications should ensure that aggregate particles possess the necessary strengths to avoid degradation during handling, construction, and trafficking.
