Uso de partículas de plástico en la fabricación de mezclas asfálticas con agregados de la localidad

Abstract

Abstract: This investigation analyzes the modified asphalt mixtures with local materials, where it is proposed to replace reused plastic waste by percentage, with the granular material in an asphalt mixture, studying its physical properties through the Marshall test. For this purpose, an asphalt design is developed, following the specifications of the Standard for Road Design Studies (NEVI 12). To make the dosage of the mixture, the bituminous, granular and plastic material was characterized. Once the design was obtained, the optimal asphalt content was found and with the resulting content the base design was obtained. Then, part of the aggregates was replaced by plastic in percentages of 3%, 5%, 10% and 16%, applying the same optimal asphalt content previously described in the design. With the analysis of samples by the Marshall method, the base sample was compared to the samples with plastic substitution, concluding that the addition of plastic improves the characteristics of the mixture in percentages of 0% to 5% substitution.
