Variasi Temperatur Pencampuran Terhadap Parameter Marshall pada Campuran Lapis Aspal Beton

Abstract

This study was conducted to determine the effect of temperature variations on the mixing process
of the asphalt concrete AC-WC (Asphalt Concrete-Wearing Course) subtle gradations in the
middle limit and lower limit of the Marshall parameters with reference to specifications of Bina
Marga, 2010.
From the results of experiments conducted that the optimum asphalt content is used to middle limit
using a asphalt content of 5,7% and 6,8% for the lower limit after that mixing was done using
temperature variation of 120 o C, 130 o C, 140 o C, 150 o C, and 160 o C.
To a mixture of Laston AC-WC subtle gradations middle limit grading 5,7% asphalt content
mixing temperature using a temperature of 120 o C, 130 o C, 140 o C, 150 o C, 160 o C and still meet all
standards of marshall parameters. Ideal mixing temperature variations in the middle limit of
mixing temperature 150 o C-160 o C. While the lower limit to the level of 6,8% asphalt content
mixing temperatures between 120 o C-160 o C did not meet the specifications, because the MQ value
below the minimum value of 250 kg / mm.
