CGSB asphalt specifications [PWGSC 1997].

“For high temperature loadings, it is recommended that the high temperature grade be
increased based on the speed and size of aircraft. As was demonstrated with the relationship
between loading frequency and stiffness (Complex modulus), standing loads greatly reduces the
asphalt modulus. SHRP currently recommends an adjustment of one grade for slow traffic and
two grades for standing traffic.
For airport loadings, based on the CGSB grades currently used, an increase of two grades is
recommended as an interim measure, for airport pavements when the airport is utilized by large
jet aircraft.
When applying the SUPERPAVE specification a degree of conservatism in the selection of the
minimum design temperature is recommended when new pavement construction is undertaken.
A reliability of 98% is considered warranted because low temperature cracking can occur with
a single occurrence of the low temperature.
When overlaying cracked asphalt or PCC pavements, the cracking will generally be controlled
more by the underlying pavement and conservatism in the selection of the low pavement
temperature is not warranted. For overlays, the low temperature selection should include
consideration of the overlay thickness as a major factor in reflective cracking. The low
temperature reliability should then be selected on the basis of the binders potential in
contributing to thermal cracking severity. This recommendation is made recognizing that the
binder selection alone will not prevent reflective cracking but needs to provide some resistance
to significant deterioration of reflected cracks.”
