This paper studies the effect of compaction temperatures on Marshall properties on a Hot Rolled Sheet-Base (HRS-Base) mixture with the addition of plastic waste. Polyethylene terephthalate (PET) type plastic waste from plastic bottle waste is used in this study as an additional material of HRS-Base mixture. The 'wet method' is used to mix the PET into HRS-Base mixture, in which the PET is pre-mixed with asphalt material at the temperatures between 160 °C to 170 °C to create modified asphalt

... re it is mixed with HRS-Base aggregates. The materials used in this study consist of PET from plastic bottle waste, 60/70 penetration asphalt, Portland cement, and aggregates. The aggregate composition used must meet HRS-Base specifications based on the Indonesian National Standard (SNI). The results showed that increasing the compaction temperature of the HRS-Base mixture had an impact on increasing density, Voids Filled with Asphalt (VFA), Marshall stability, and Marshall Quotient (MQ), while the values of Voids in Mix (VIM), Voids in Mineral Aggregates (VMA), and Flow decreased. In addition, HRS-Base without the addition of PET plastic (conventional HRS-Base) and HRS-Base with the addition of PET plastic (modified HRS-Base) were compared. Conventional HRS-Base has a density value, Voids Filled with Asphalt (VFA), and Flow higher than those of modified HRS-Base. While, the value of Voids in Mix (VIM), Voids in Mineral Aggregates (VMA), and Marshall stability of conventional HRS-Base are lower than those of modified HRS-Base.
