%X The recovery of plastic waste has a positive impact on two fronts: The environment,
through waste reduction, and the economy, through its use in road construction.
This work involves recycling plastic variants such as Polypropylene (PP) 50%
and LDPE (Low Density Polyethylene) 50% in proportions of 2% to 8%,
incorporated into a 0/14 BBSG. The results of the Marshall test gave stability
values ranging from 826 to 1523 kg and creep values from 5.5 to 2.45 mm. The
Duriez test gave r/R values ranging from 0.769 to 0.786, with water absorption
percentages from 2.24% to 0.69%. The PCG test at 80 gyrations gave void
percentages ranging from 11.9% to 5.23%. The rutting test gives a rutting depth
percentage that drops at 30,000 cycles from 11.5% to 1.3%. This study shows a
considerable increase in the mechanical characteristics of asphalt mixes by
adding plastic waste.
