• Abstract:
  A limited amount of pavement temperature data was available when the Strategic Highway Research Program (SHRP) developed its Superpave system. As such, specifications for SHRP’s Superpave Performance Grade (PG) asphalt binders were based on the lowest and highest temperatures expected at a site. Recently, the Long Term Pavement Performance (LTPP) program used data from its Seasonal Monitoring Program to quantify the relationship between air and pavement temperatures. This evaluation resulted in the development of improved low and high pavement temperature models for selecting Superpave PG asphalt binders. Now these improved models are available in a new software program called LTPPBind.
