Pavement temperature model for Canadian Asphalt Binder selection: Introduction to the CPT model

The selection of a climate-appropriate asphalt binder is essential in ensuring the longevity of pavement surfaces. As the selection methodology depends on the pavement's temperature, several models predict pavement temperatures based on recorded ambient air temperatures and other related factors. A commonality between the most predominant pavement temperature models is the geographical limitations to their application. As a result, widely used models such as long-term pavement performance (LTPP) and Strategic Highway Research Program (SHRP) do not return accurate values for more Northern temperatures, as observed in Canada. Thus, a new pavement temperature model has been developed for use across Canadian pavements. The resulting model returned satisfactory accuracy upon validation and represented a good alternative for Canadian pavement designers. Additionally, a software tool title CABS has been developed to select asphalt binders based on the predicted pavement temperatures to implement the model.
