Question
Transcribed Image Text:An asphalt binder is intended to be used in a climate with maximum 7-day pavement
temperature of 73 •C and minimum pavement temperature of -18•C. Following is the
SHRP tests results on the asphalt binder. This asphalt
meet the
requirements for original binder,
_meet the requirements for RTFO aging and
meet the requirements for PAV aging
Original Binder
DSR at 76 °C: G*=0.96 kPa, ô=65•
RTFO Aged Binder
Mass lost: 0.55 %
DSR at 76 °C :G*=1.72 kPa, ô=54•
PAV Aged Binder
DSR at 31 •C : G*=8520 kPa, ô=37•
BBR at -12 °C and 60 sec : Stiffness = 289 MPa , m-value = 0.281
DTT at -12 C : 2.2%
