Pemanfaatan Sedimen Aquatis Sebagai Filler dalam Campuran Aspal Beton Lapis Aus

Abstract

The sedimentation of Lake Limboto causes silting so that dredging is needed to be used later in road construction. This study aims to test the waste of Lake Limboto can be used as a filler in the AC-WC mixture. For the percentage of filler content in the mixture and analyze the value of Marshall characteristics using Limboto Lake sediments. Aggregate originating from AMP PT. Cahaya Nusa Sulutarindo is located in the Isimu sub-district, Gorontalo Regency. The test was carried out at the Engineering LAB, Gorontalo State Civil University. The test method is the Marshall Test which refers to the general specifications of the 2018 Revision II Road and Bridge Highways. Marshall AC-WC mixture uses an optimum asphalt content of 6.35%: sediment variation 0.1% and 0.2% all values of Marshall characteristics meet the requirements according to the general specifications for 2018 revised road and bridge construction work. Variation of 0.1% is obtained the value density 2.304; VIM 3.66; VMAs 17.91; VFA 79.56; free 1259.44; stream 3.18; a variation of 0.2% obtained a density value of 2,314; VIM 3.21; VMA 17.52; VFA 81.68; fortress 1208.08; flow 3.00. The ideal mixture material for the AC-WC mixture using Lake Limboto sediment with an optimum asphalt content of 6.35% obtained 14.0% coarse aggregate (CA) of 157.3 gr, medium aggregate (MA) 34.0% of 382.1 gr and 52.0% fine aggregate (FA) of 584.4 g without sediment, for variations of 0.1% sediment of 0.6 g and 0.2% of 1.2 g.
