Análisis del ruido neumáticopavimento de la vía Loja Zamora

Abstract

Abstract:This research analyzes noise as a negative environmental impact from the tire/pavement interface, using the Loja-Zamora road as the object of study. This road is a logistics corridor that acts as a bridge between two regions in southern Ecuador. The methodology governing the study was formulated around the Statistical Steps (SPB) method, as outlined in ISO 11819-1:2023, evaluating the maximum and equivalent sound pressure levels at five critical points characterized by vulnerable receptors. The direct correlation between speeds and peak noise levels resulted in a high Statistical Steps Index value, between 84 and 87 dB. The findings indicate that ambient noise during the daytime, with levels of 69 and 73 dB, exceeds the limits established in the national TULSMA regulations, which range from 55 to 65 dB, thus demonstrating a negative impact on public health. In response, the study proposes mitigation using concrete acoustic barriers with a theoretical design and a reference budget for their implementation.
