Welcome to the Memorial University of Newfoundland - Canadian Asphalt Binder Selection (CABS) tool! With this tool, pavement temperatures can be calculated using three different pavement temperature models: LTPP, SHRP, and the newly developed Canadian Pavement Temperature (CPT) Model.
SHRP -Strategic Highway Research Program (1)
The SHRP pavement temperature model calculates high pavement temperature using ambient air temperature and latitude. This model equates low ambient air temperature to low pavement temperature for a conservative approach. Many modifications of the SHRP model exist, including one known as C-SHRP. This is an equation developed to predict low pavement temperatures in Canada, as the original method has been found less effective in Canada.
LTPP – Long-Term Pavement Performance (2)
LTPP pavement temperature model was developed to help State transportation departments select the most suitable performance-grade binder for a particular site based on the American Association of State and Highway Transportation Officials (AASHTO) M320-10 and AASHTO M332-14 standards.The LTPP pavement temperature model is developed based on pavement sites located between latitudes of 27 degrees (Texas) and 52 degrees (Southern Canada). The model relies on latitude and ambient air temperature to predict corresponding pavement temperatures.
CPT – Canadian Pavement Temperature (3)
The CPT model is a recently developed pavement temperature model for use specifically in Canada. CPT functions by geographically dividing Canada into clusters of unique climatic zones. Independent temperature prediction equations were developed for each of these zones to accurately encompass the complex and varied Canadian climate.
