| description | Nowadays, a high-quality and reliable asphalt pavement is desirable and
become an important aspect of the highway asphalt pavement performance. A higherquality
pavement can make regular rides safer and more comfortable. Asphalt binder
modification and reinforced asphalt mixes are among the innovations to improve
asphalt pavement performance. In this research study, asphalt mixture that was
reinforced with Super Fiber Mix (SFM) was chosen as an alternative for asphalt
pavement improvement. In the past five decades, the use of fibers was investigated and
implemented in asphalt mixtures to improve pavement performance worldwide. The
primary goal of this study was to examine the effect of additional fiber on laboratory
performance and to compare the modified asphalt to conventional asphalt. The report
outlines the features and properties of modified asphalt (SFM) blended with
polypropylene and aramid fibers. The laboratory assessments for five major tests were
conducted and those tests are the Marshall Stability and Flow test, Indirect Tensile
Strength test, Resilient Modulus test, Dynamic Creep Modulus test, and the rutting test.
Based on the results, the Marshall's stability values of the reinforced asphalt sample
improved as much as 17.8% as compared to the conventional mixture. The flow values
for both conventional and modified samples are within the allowable range. However,
the flow value for the modified sample is lower (3.1 mm) as compared to 3.5 mm of the
conventional asphalt, which implies that the modified asphalt mixture was stiffer. The
SFM contains aramid fiber, which has high tensile strength and is proven through the
increased indirect tensile strength results as well. The SFM also help to increase the
Resilient Modulus value by approximately 24%. The dynamic creep test showed that
the use of the SFM improved the modulus values and passed the minimum requirement. Meanwhile, the rut depths for both control and modified samples conform to the
minimum requirement of 12 mm for rut depth by the PWD specification. In this case,
the asphalt mixture enforced with the SFM exhibits similar performance with the
conventional asphalt mixture.
Overall, the asphalt mixture reinforced with the SFM exhibits better engineering
properties as compared to the conventional asphalt mixture. |
