Laboratory evaluation of fatigue life characteristics of polymer modified porous asphalt: A dissipated energy approach
HighlightsPorous asphalt specimens with SBS polymer modified binder were made.Four-point beam fatigue tests at ambient and freezing temperatures were performed.Statistical models of relation between dissipated energy and fatigue life have been derived.Porous asphalt can be a good alternative (from fatigue viewpoint) instead of HMA in rainy areas.
AbstractPorous asphalt (PA) is considered as one of the efficient solutions to mitigate the dangerous aspects of runoff. Beside, fatigue cracking, as the most important structural failure in asphalt mixtures, plays a key role to keep performance and durability of porous asphalt. In this experimental research, fatigue characteristics of porous asphalt with dissipated energy viewpoint were investigated. SBS polymer modified binder and limestone materials were employed to make PA samples. In order to examine the porous asphalt fatigue life, 4-point beam fatigue test was conducted. A strain control loading with various strain levels at two temperatures was selected as the test conditions. Finally, two models to calibrate dissipated energy and fatigue life of porous asphalt were presented. Dissipated energy models to estimate of dissipated energy in various cycles of load repetitions are applicable. Also, reverse form of these models could be useful to predict fatigue life based on total dissipated energy.
