| Summary: | Asphalt is processed waste oil used for highway pavement. In general, the existing
asphalt pavement in the field is produced by PT. Pertamina from the rest of
refined petroleum. The cost of production of petroleum asphalt tend to be
expensive to make an excuse to produce bitumen from other raw materials
cheaper. Raw materials, from oil palm shell liquid smoke called bio asphalt.
The initial process of making bio-asphalt is preceded by pyrolysis process in
advance to get the tar and oil palm shell liquid smoke. After the results obtained
from the pyrolysis process, is the process of distillation to vaporize liquid smoke
residue and precipitate who called bio asphalt. Bio asphalt that have been obtained
will then be a matter for mixing asphalt with notes pertamina not reduce the
quality of the asphalt Pertamina. Mixing bio bitumen asphalt against Pertamina is
1 % - 10 % of the weight of asphalt pertamia that will be tested. Tests performed
include penetration testing asphalt, asphalt density testing, testing softening point,
and ductility testing to determine the engineering properties of mixing between
Pertamina and bio bitumen asphalt in order to obtain the maximum level of the
asphalt mixing.
Distilled asphalt tend not to harden, then combined with the asphalt pavement
from Pertamina to do some testing first. After doing some testing at the end of bio
Obtain maximum mixing asphalt with asphalt pertamina appropriate quality
requirements by mixing asphalt is asphalt Pertamina 99% and 1% bio asphalt. The
percentage of eligible asphalt is then further testing using testing aggregate
LASTON ie marshall and marshall immersion testing to determine the
engineering properties of mixtures containing LASTON bioaspal for heavy traffic
category.
