Thermal oxidation and UV exposure contribute to major changes in the physicochem. and rheol. properties of asphalt binder, leading to the deterioration of pavements. This paper investigates the merits of grafting bio-derived mols. onto particles of crumb rubber to create bio-modified rubberized asphalt binder with enhanced resistance to thermal aging and UV aging. The bio-modification of the crumb rubber was made via a hybrid process where mols. of waste cooking oil were grafted to rubber with the help of microwave radiation. The evolution of bio-modified rubberized asphalt during thermal aging and UV aging was then characterized and compared with those of conventional rubberized asphalt. Study results showed biomodification was effective to delay both thermal aging and UV aging. However, the effectiveness varied with the type of aging with the resistance to thermal aging being enhanced by 35%-84% and the resistance to UV aging being enhanced by 34-106%. Overall, the synergy between waste cooking oil, crumb rubber, and asphalt binder led to a significant improvement in the resistance against aging, thereby promoting sustainability in construction while making use of two waste streams including waste cooking oil and crumb rubber from scrap tire. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0SDS of cas: 106-73-0).
Methyl heptanoate (cas: 106-73-0) belongs to esters. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.SDS of cas: 106-73-0
