| Summary: | In Malaysia, 80% of its roads are from flexible pavement rather than
rigid pavement. The asphalt binder material is supplied by the quarry
for its aggregates and from the manufacturer for its asphalt binder. In
order, material such as limestone aggregate has been used to replace
the material that commonly used in the mixture. Limestone aggregate
is one of the most durable of all natural building materials. The main
objective of this study is to overcome the weakness of the strength
problem by using the method Marshall Stability Test. The material that
was used for aggregate were limestone and granite. The properties for
aggregate tested were Sieve Analysis, Aggregate Impact Value (AIV),
Flakiness and Elongation. Furthermore, asphalt binder grade 60/70
penetration properties were performed by softening point and
penetration testing. Next, the method used was a mixture design by Hot
Mix Asphalt (HMA) and Marshall Mix design. Marshall stability test was
employed to evaluate the performance of asphalt mixture. At 0, 25, 50,
70, and 100% of the aggregate total weight, the limestone was mixed
with asphalt binder grade 60/70 penetration. The stiffness was
demonstrated that the control sample is 74.481 kN/mm meanwhile,
the optimal limestone mixture was obtained at 25% which is 69.664
kN/mm. The compressive test shown that all the sample are required
followed the JKR specification for stiffness which is 2.6 kN/mm.
Therefore, potential of limestone aggregate in asphalt mixture has been
implement in road construction |
