Performance analysis of stone matrix asphalt (sma) mixture with crumb rubber as additive and unsaturated polyester resin as stabilizer in view of marshall parameters / Amimmatur Rohmah

Abstrak
High traffic loads and tropical climates can accelerate pavement deterioration. Stone Mastic Asphalt (SMA) is an advanced asphalt mixture with a gap-graded structure that offers good deformation resistance and durability. The addition of crumb rubber (CR) to the asphalt mixture has been proven effective in correcting deficiencies in conventional asphalt mixtures while unsaturated polyester resin (UPR) used as a stabilizer can enhance adhesion and strengthen the bond between aggregate and asphalt. This research aims to (1) describe the characteristics of the constituent materials in the SMA mixture (2) analyze the performance of the SMA mixture with CR as an additive and UPR as a stabilizer based on Marshall parameters (3) analyze the performance of the SMA mixture with CR as an additive and UPR as a stabilizer through the Retained Strength Index (RSI) test and (4) analyze the performance of the SMA mixture with CR as an additive and UPR as a stabilizer through the draindown test. This study was conducted using an experimental method (laboratory research) starting from the selection and testing of SMA mixture materials including aggregates asphalt filler and coconut fiber. Test specimens were then made to determine the optimum asphalt content (OAC) with asphalt content variations of 5% 5.5% 6% 6.5% and 7%. Afterward specimens were made using the determined OAC and crumb rubber content variations of 0% 1% 2% and 3% to determine the optimum CR content (OCR). The obtained OAC and OCR were then used to create specimens with UPR content variations of 0% 1% 2% and 3%. RSI tests were carried out with soaking durations of 30 minutes and 24 hours followed by binder draindown tests and data analysis. The results of this study are as follows (1) the constituent materials of the SMA mixture mdash coarse aggregate fine aggregate filler cellulose fiber and asphalt mdash meet the 2018 Bina Marga general specifications (2) as the UPR content increases (combined with 1.2% OCR) the values of stability flow VIM and VMA increase while VFA and MQ decrease (3) the highest RSI value was 93.19% at 1% CR UPR and decreased thereafter (4) the binder draindown value decreased as the CR UPR content increased reaching 0.12% at 3% CR UPR. CR and UPR were able to increase the viscosity of asphalt thereby reducing the likelihood of asphalt draindown in the mixture.
