Rutting Characterisation of EVA Modified Bitumen for High Modulus Asphalt Mixes (HiMA)
The present study focuses on the rutting performance evaluation of the hard grade bitumen and other high performing polymer modified binders for use in high modulus asphalt mixes. The polymer modified binders were produced through modification of VG-40 bitumen using different combinations of EVA-18 and EVA-28 polymers. Temperature and frequency oscillation and MSCR tests were conducted on the binders to study the rheological and rutting characteristics and mix rut depth measured in wheel tracker. Since the increase in the proportion of EVA-18 from 1 to 2%, decreased the ductility significantly, a combination of EVA-18 and EVA-28 was considered to improve the elastic nature of the modified binder. The Jnr and percent recovery of V4E12 and V4E13 binders and the mix rut depths suggest better rut resistance of these binders. The present study indicates that V4E12 and V4E13 are suitable for producing high modulus mixes with higher rutting resistance.
