| 摘要： | Key findings of the various researchers involved in the Strategic Highway Research Program (SHRP) asphalt program are described. Emphasized are those fundamental chemical and physical properties of the binder that relate to its susceptibility to various distresses. Consideration and evaluation of the polar and nonpolar molecules assists in understanding the performance of a given asphalt. The polars largely dictate the ability of an asphalt to resist permanent deformation. Low temperature cracking and fatigue cracking are largely influenced by the nonpolar fraction. The impact of aging and asphalt compatibility on these distress modes is also discussed. |
