Influence of the improvement of 0.2%, 0.3% and 0.4% of polyethylene terephthalate on the strength and permeability properties of concrete pavement

Abstract

The objective of the research is to determine the effect of the use of recycled PET on the permeability, compressive strength, and flexure of the permeable pavement f'c=280 kg/cm2. The methodology is applied type, experimental design, and quantitative approach. Permeable concrete is a type of porous pavement that seeks to solve the problems of traditional pavements, since traditional pavements, by not having an adequate gutter, tend to accumulate rainwater causing various accidents due to lack of inertia and decrease in pavement life. PET is a material that is found everywhere as waste, this material tends to resist tensile loads. The results show that 0.3% PET improves compressive strength, while 0.4% PET improves flexing and permeability. It is concluded that if the greatest resistance is sought, a lower dosage of PET is used and if greater flexing and permeability is sought, a higher percentage of PET is used. This study showed that PET does have a significant influence on the compressive strength, flexural strength, and permeability of pervious concrete.
