  • Abstract:
  • This investigation mainly aims of reusing plastic waste, specifically LDPE (low-density polyethylene) as well as BOF steel slag, thereby decreasing the overall construction cost of roads and resolving the problem of solid waste management. The LDPE waste plastic of exactly 5.16% by weight of optimum bitumen content is mixed with the bitumen VG 30 of 60/70 penetration grade (grade most commonly used in the state) and performing softening point test, penetration, and ductility test. The percentage of bitumen content used in each of the three samples is 4.25%, 4.50%, and 4.75% by weight of total aggregate. In this analysis, Steel slag, specifically basic oxygen furnace BOF in the aggregate form, was used in the percentage of 10%, 15%, and 20% by total weight conventional aggregate. A mix design of DBM Grade II is prepared according to Indian standards and performs a gradation test (sieve analysis), water absorption test, and specific gravity test of the aggregate. The asphaltic mix of a modified specimen is tested with the Marshall stability and flow test and compared with the unmodified one. The analysis found out to be a maximum increase of stability value at binder content @4.5% and steel slag @15% by 2.4% of the unmodified mix with a corresponding increase in its flow value by 3.65%. this shows the mix is considerably more resistant to rutting, distortion, and overall stability of the pavement.
