| description | Pavement deformation is a common problem in flexible pavements in
Malaysia due to poor material quality and quantity. To address this
issue, basalt aggregates are being used as replacement aggregates in
Hot Mix Asphalt (HMA) mixtures. The study aims to analyze the
characteristics and variability of basalt aggregates and asphalt binder
materials, as well as evaluate the volumetric parameters of HMA using
basalt aggregate. Additionally, a marshall stability test would been
conducted to analyze the performance of the mix design using basalt
aggregate. Based on the average percentage in review studies, the
basalt aggregate employed in this study is 0, 25, 50, 75, and 100% by
weight of total aggregate. The study would been carried out to assess
the stiffness of asphalt mixtures using basalt aggregate at higher mix
temperatures. The aggregate that would be used in this study were
granite and basalt and asphalt binder grade 60/70 as a bonding agent.
To mix the material, a marshall mix design would be used in this study.
Then, a marshall stability test would be conducted to analyze the
performance of the mix design using basalt aggregate. Based on the
result of Marshall test, the stiffness value for optimal basalt aggregate
mixture was obtained at 25% which is 80.376 kN/mm, while the
control sample stiffness value is 77.941 kN/mm. The compressive test
shown that all the samples are followed the JKR specification for
stiffness which is more than 2.6 kN/mm. This experiment indicates that
a mixture of asphalt and basalt aggregate replacement fulfilled the
requirements and can still be employed for improving the pavement |
