fis-2142	Fallah Tafti, Mehdi; Hoseini Aqda, Seyyed Abuzar; Motamedi, Hamed	The impacts of type and proportion of five different asphalt modifiers on the low temperature fracture toughness and fracture energy of modified HMA	2018	17	.pdf	application/pdf	9171	506	49	The results of their experiments indicated that for both examined percentage of air voids (i.e. 3% and 7%), modified asphalt mixtures demonstrated a higher fracture toughness in comparison with the unmodified mixtures. This figure indicates a strong and direct relationship between energy absorbance capability of modified asphalt mixtures and their fracture toughness when they are subjected to mode I loading at -15°C temperature.	cache/fis-2142.pdf	txt/fis-2142.txt
