| dc.description.abstract | Failure or damage to the Asphalt Concrete-Wearing Course pavement
before entering its design life is still common. One of the factors that
influence failure, namely the material used in the mixture. Preventing
damage to the pavement can be done by improving the quality of the
pavement. In this study, LDPE and rubber tire additives were used to
obtain the additive effect on the AC-CW pavement in terms of volumetric,
IRI, and skid resistance values. Primary data was obtained from tests of
specific gravity, softening point, and penetration of modified asphalt,
while secondary data was obtained from research. Test specimens with
additive levels of 0%, 2%, 4%, 6%, and 8% for optimum asphalt content
were made after the proportions of aggregate and asphalt were according
to specifications. After that, testing was carried out on each specimen by
volumetric testing, Mean Texture Depth testing using the Sand Patch
Method, Skid Resistance testing with the British Pendulum Tester, and
Marshall Properties testing with the Marshall Test. The results showed
that the effect of using LDPE plastic waste was better in improving
volumetric values compared to using waste rubber tires. The effect of
additives on unevenness showed that the unevenness value of rubber tire
waste was better than LDPE plastic waste. The effect of LDPE plastic
waste on the Skid Resistance value is better than rubber tire waste. The
asphalt content of LDPE plastic waste obtained was 5.52% and the asphalt
content of rubber tire waste obtained was 3.7%. | en_US |
