Effect of Short-Term Ageing on Mechanical Characteristics of Modified Bituminous Binders
The findings of a laboratory investigation into the ageing of asphalt mix are presented in this paper. VG30 and NRMB40, two binders, are investigated. Anti-oxidants were added to cashew nut shell liquid (CNSL) at a rate of 1–3% by weight of binder, with a 1% increase, in this research. Physical parameters of the binder, such as softening point, viscosity, ductility, and penetration, were used to assess the impact of employing CNSL in the binder. Fourier transform infrared spectroscopy is used to look at the characteristics of CNSL (FTIR). Multiple stress creep recovery test (MSCR) results using a dynamic shear rheometer show that adding CNSL to the VG30 increased the value of recovery at 1% CNSL, indicating better fatigue resistance; however, there are no significant effects on NRMB40 fatigue resistance, which continues to decrease as CNSL content increases. The fatigue test results acquired from repeated load tests for unaged and aged mixes are analysed using resilient modulus, which verifies the fatigue resistance values provided by MSCR.
