| Popis: | Plastic waste has a negative effect on the environment since it could not be decomposed easily, and it could decrease soil fertility. One way to decrease plastic waste is by mixing it with sand to make paving blocks, because the characteristic of plastic is elastic and flexible, so it is expected that the material will be ductile and strong. Material of this study used LDPE (Low Density Polyethylene) plastic which was chopped and mixed with 6 mesh sand with variation of 1 kg (plastic): 5 kg (sand) and 1 kg (plastic): 7 kg (sand) (1:5 and 1:7). The sand was inserted into mixing machine with 200 °C temperature for 5-10 minutes, after that the chopped plastic was inserted and mixed for 30-35 minutes. Molding process was done by pressure tool. After that testing was done by using compressive machine and run over vehicle. The research result showed that the lowest damage occurred on plastic and sand composition of 1:5 as much as 0.113% and had compressive strength 16.667 MPa, and the highest damage occurred on plastic and sand composition of 1:7 as much 0.267% and had compressive strength 12.963 MPa. |
