Experimental Investigation on Aging Behavior of Bitumen Mastic with Hydrated Lime Using FTIR Spectroscopy

Harnadh, K. L. A. V. / Nivitha, M. R. / Padmarekha, A.

To reduce moisture damage, anti-stripping agents are commonly used for the surface course of bituminous pavements. While a wide variety of anti-stripping agents are currently available, hydrated lime (HL) is widely used. The present study focused on studying the aging characteristics of bitumen and hydrated lime-treated mastic by using FTIR spectroscopy. HL was added to bitumen in contents of 20, 30, and 40% weight. The HL-treated mastics were oxidized at a constant temperature of 100 ℃ by varying the aging time. HL-treated mastics were evaluated for their aging compounds using FTIR spectroscopy. Results of obtained unaged and aged spectra were analyzed by calculating carbonyl and sulfoxide indices. Analysis of the spectra of aged mastic exhibited that the carbonyl indices increase with aging although at different rates depending on the aging duration and the dosage of lime. The sulfoxide compounds however exhibited very less sensitivity to duration of aging and dosage.
