| Summary: | Adding plastic waste (polymer) into asphalt is one of many ways to improve the
quality of asphalt. Polymer (SBS) has opportunity to be used as a binder in asphalt
pavement, that way the asphalt will be more elastic and durable with mixing
Styrene Butadiane Styrene (SBS) into Asphalt Pen 60/70.
According to basic rheology testing on asphalt pen 60/70 and Styrene Butadiane
Styrene (SBS), SBS addition are decreasing the penetration value. On the
contrary, softening point value and elastic recovery value are increasing and
there’s no effect on ductility value. However, viscosity value are increasing the
mixing temperature and compacting temperature in addition of SBS.
According to mechanistic rheology testing with DSR tool (time sweep), the result
shows that SBS addition increase the Complex Shear Modulus (G*) and Elastic
Modulus (E*) value. Meanwhile, it decrease the Phase Angle (?) and Strain (?)
value. Moreover, the mechanistic rheology testing (temperature sweep) shows that
SBS addition decrease the Complex Shear Modulus (G*) value and increase the
Phase Angle (?) value. Other than that, it shows that higher SBS content will
increase the capability of pavement to resist the failures such as permanent
deformation and fatigue cracking. |
