ALTERNATIF PEMAKAIAN JENIS-JENIS BAHAN PENGISIAN (FILLER) PADA CAMPURAN ASPHALT CONCRETE HOT MIX

Abstract

The safety and comfortable of the user of road is determined by quality of
its surface course which can be stated by the index value of its surface. The use of Hot
Rolled Sheet (HRS) as a surface course is very famous in Indonesia. So it is a need to
improve its quality. Because of the lack of its filler at a natural aggregation and the
limit of production of stone ash from the stone crusher, it is required an endeavour to
find out the alternative filler which can replace the stone ash functions in the Hot
Rolled Sheet mixture. For this reason, it will be tried to use the ash of limestone and
“Portland” cement as alternative filler. A research has been undertaken in a laboratory
by making a specimen as a sample and treatment to different fillers, a various asphalt
quantity and aggregation of gradation which fulfill the specification from Bina Marga.
The result shows that by different fillers will make a different characteristic of
mixture, but on certain asphalt quantity the three treatments that is filler of stone ash,
ash of limestone and “Portland” cement, still in line with the specification from Bina
Marga.
