| Abstract | It is recognized that polymer-modified agents or modifiers play a special role in
asphalt cement or binder contained in asphalt concrete mixtures. Several examinations
have found that the addition of these modifiers to asphalt cement improves the physical
properties of the mix. Though many different types of modifiers are known, ARBOCEL
and STYRELF are more prevalent because of the better performance of asphalt paving
mixtures mixed with them and their simplicity to use for Thailand highway construction.
The suitabilities of ARBOCEL and STYRELF as modified agents for asphalt
concrete mixtures were examined in this research. Viscous Test, Elastic Test and Thermal
of binders incorporating these modifiers were measured and compared to the properties
of an original asphalt cement, AC 60170. Marshall mix design and Stability test were
performed on Marshall specimens both without and with addition of these modifiers in
various quantities for obtaining the optimum binder content of each quantity. Creep
Compliance Test, Tensile Strength Test, Resilient Modulus Test, Fatigue Test, Moisture
Damage Sensitivity Test and Weathering Treatment Test were performed on all Marshall
specimens at optimum binder content. Physical properties of both original and modified
asphalt mixtures were measured and compared each other. The results showed that adding
ARBOCEL or STYRELF at certain percentages can produce a mixture of better properties
than a mixture without an added modifier, namely, increase resistance to rutting and
cracking, increase resistance to aging caused by fatigue and moisture. The results also
showed that STYRELF is more potential than ARBOCEL in terms of improving the
physical properties of asphalt concrete mixtures, however its life-cycle cost is higher than
that of the ARBOCEL additive. |
