THE EFFECT OF SEA WATER IMMERSION ON BUTON ASPHALT (AS-BUTON) MIXTURE
Keywords:Marshall characteristics, asbuton, asphalt concrete wearing course, sea water immersion, asphalt mixture
AbstractOne of the causes of flexible pavement damage is being submerged in water with a high acidity, such as sea water. To overcome this condition, a study on the use of Buton asphalt as a mixture of modified asphalt (as-buton) was conducted. The advantages of Buton asphalt are that it has higher adhesion and is more resistant to temperature changes. As-buton modification by mixing Lawele Buton Asphalt Southeast Sulawesi, Indonesia with oil asphalt pen 60/70. This study focuses on determining the effect of the addition of Buton asphalt to the modified asphalt mixture and the effect of sea water immersion on asphalt concrete modification Buton asphalt (as-buton) based on the Marshall characteristic test. The percentage by weight of Buton asphalt used is 5%, 7.5%, and 10%. The immersion was carried out in two conditions, namely freshwater immersion and sea water immersion for up to 24 hours at a temperature of 30°C. The result of this study show that the addition of Buton asphalt increase the value of stability, void in mixture, Marshall quotient, and void in mineral aggregate, but reduce the value of flow, void filled with asphalt, and density. The increase of stability and marshall quotient value in sea water immersion due to the addition of buton asphalt was higher than that in freshwater. The stability value of the 10% modified as-buton mixture in freshwater immersion increased by 169.338 kg (14.61%) and in sea water immersion increased by 1261.669 kg (55.65%).
