Abstract
This research discusses the effect of stirring time on the Marshall characteristics of Retona
Blend 55 asphalt. Marshall characteristics, namely VMA, VIM, VFA, stability, flow and
Marshall Quotient were determined. The Retona Blend 55, according to accordance with
the Bina Marga could improve the hot mix asphalt performance. This is particular to
prevent early cracking damage for road with heavy traffic loading and high temperature.
In this research, the Retona Blend 55 asphalt was made by varying the stirring time from
0.5 to 5 minutes. Initially, the Optimum Asphalt Content (KAO) by varying the stirring time
was determined. From the KAO value, approximately 30 samples were produced. The
samples were used for Standard Marshall and Immersion Marshall tests. Another
parameter, i.e. IRS, was determined from those tests, which can be used to obtain the
Optimum Stirring Time (WPO). The result shows that WPO at 1.5 minutes gave KAO of
5%. This mix was found more durable due to high IRS.
