Abstract

  • We were asked by Victor Johnson with Geneva Rock to create a model within their existing spreadsheet to predict the voidsin mineral aggregate (VMA) of any givenasphalt mix design.
  • UDOT and City specifications require a specific VMAfor all asphalt designs.
  • Having an accurate predictive modelcould saveGeneva Rock25% on the cost of a mix design
  • The 0.45 power curve plots the cumulative percent passing of an aggregate vs the sieve opening size to the0.45 power
