Using Polymer Modified Asphalt Emulsions in Surface Treatments A ...

2. Fatigue Cracking (repetitive loading/unloading);
3. Raveling (stone loss);
4. Rutting (permanent deformation, high temperature susceptibility); and,
5. Aging (58).
Table 3 presents a matrix adapted from the SHRP review, and depicts the reported
relationships between various asphalt physical and chemical properties and each of the
performance variables enumerated above. The arrows in Table 3 indicate whether the
performance criteria increases or decreases in magnitude as the corresponding
physical or chemical property increases or decreases. For example, when viscosity
increases, so do measured fatigue and low temperature cracking.
