Abstract

The characteristics of natural rubber greatly influence the quality of asphalt modified with natural rubber. This research uses natural rubber of the Technical Specified Rubber (TSR) 20 type, which in Indonesia is called Standard Indonesian Rubber (SIR) 20 as the raw material. The sulfur vulcanization material is expected to increase crosslinks so that it can increase the resistance of natural rubber to hot asphalt and can improve the quality of rubberized asphalt. This research was designed by varying the sulfur dosage and vulcanization duration. The sulfur dosage used varies, namely 5; 10; 15; 20 parts per hundreed rubber (phr). The duration of vulcanization time at 140 °C for each dose of sulfur is 0;30;60;90;120 min. The compound or vulcanisate is then mixed into the asphalt at a temperature of 160–170 °C with a dose of 2 % rubber and 98 % asphalt. Based on the research results, it is known that increasing the sulfur dosage and vulcanization time duration produces rubber that is more resistant to oil through testing for solubility and swelling in toluene. The unvulcanized compound dissolves in toluene, while the vulcanizate swelling ratio decreases with increasing sulfur dosage (790 to 482 %). Increasing the sulfur dosage and the duration of vulcanization time produces harder rubber so that the duration of mixing into asphalt increases from 1.5 h to 5.5 h. The addition of sulfur dosage and vulcanization time duration can increase the original Performance Grade (PG) and PG after Rolling Thin Film Oven Test (RTFOT) when compared to original asphalt. Original PG of rubberized asphalt obtained from this research is 69.8 to 90.4 °C compared to original asphalt PG which is only 66.7 °C. PG after RTFOT was obtained between 60.3 to 88.4 °C compared to original asphalt PG which was only 64 °C. This research data can be useful in the design of rubber compounds and vulcanizates which can be selected by considering process engineering, processing machines and economic aspects in the production of rubberized asphalt.

期刊介绍： Data in Brief provides a way for researchers to easily share and reuse each other''s datasets by publishing data articles that: -Thoroughly describe your data, facilitating reproducibility. -Make your data, which is often buried in supplementary material, easier to find. -Increase traffic towards associated research articles and data, leading to more citations. -Open up doors for new collaborations. Because you never know what data will be useful to someone else, Data in Brief welcomes submissions that describe data from all research areas.
