Research Projects
Laboratory Performance of Asphalt Mixtures Made With CRM Binders

This project is the next logical step to follow research on the high-temperature and low-temperature properties of rubber modified binders. It will involve the exploration of the effect of several different variables on several different mix performance properties of hot mix asphalt (HMA) made with rubber-modified asphalt binders (RMAB). Several different binder and aggregate sources will be used in the study, as well as the same variables that were used in the high- and low-temperature properties studies:

  1. Crumb rubber processing method (cryogenic vs. ambient)
  2. Type of crumb rubber (truck tire vs. passenger car tire)
  3. Amount of crumb rubber
  4. Size of crumb rubber

Some of the mixture performance properties that will be tested include:

  1. Rut resistance
  2. Fatigue resistance
  3. Moisture susceptibility
  4. Modulus of resilience
