Abstract To understand the effects of filler-asphalt ratio on different properties of lignin and polyester fiber reinforced
shape memory polyurethane (SMPU)/styrene butadiene styrene (SBS) composite modified asphalt mortar
(PSAM), as well as to reveal the reinforcing and toughening mechanisms of lignin and polyester fibers on PSAM,
SMPU, SBS and mineral powder were first utilized to prepare PSAM. Then the conventional, rheological and anticracking properties of lignin fiber reinforced PSAM (LFAM) and polyester fiber reinforced PSAM (PFAM) at different filler-asphalt ratios were characterized. Test results indicate that the shear strength, deformation resistance
and viscosity are increased after adding 0.8wt% lignin fiber or… More >
