Perubahan Morfologi Dari Modifikasi Liquid Natural Rubber - Aspal Menggunakan Emulsifier Triton X - 114

Abstract

Research has been done on polymer asphalt modification, where asphalt is mixed with Liquid Natural Rubber (LNR) from a mixture of Triton X – 114 and phenylhidrazine. Where the preparation and characterization of Liquid Natural Rubber (LNR) as a compatibliser, Triton X – 114 as an emulsifier and phenylhidrazine as an oxidative degrader in the depolymerization process. The first thing to do was dilution of concentrated latex using Triton X – 114 and carried out with oxidative degradation using phenylhidrazine/O2 at 55 for 3 x 24 hours and then characterized, molecular weight analysis using Ostwald Viscometer and Brookfield Viscometer and morphological changes by SEM analysis. The resulting LNR product has a molecular weight of 12,5892 x 102 by Ostwald Viscometer analysis which is completely soluble in toluene solvent. Analysis using a Brookfield Viskometer resulted in the appropriate specifications based on the 2010 revision of the 2012 Bina Marga with the viscosity value at a temperature of 135 is 300 cP shows the optimum result of the asphalt – LNR variation at a temperature of 135 is the variation of asphalt – LNR 40:60 which is in accordance with the specification of Bina Marga as an ingredient in asphalt binders. The second step is to modify asphalt – LNR ratio (20:80 ; 40:60; 60:40 ; 80:20) and the characterized using SEM analysis to determine the morphological changes.
