CO₂ emissions of an asphalt pavement in kg of CO₂ per m2

Abstract

Climate change is one of the world's major problems and concerns the entire human population as its effects are global in scope. Climate change is driven by the greenhouse effect, which is generated by greenhouse gases (GHG). The construction industry is important in the development of a country, both economically and culturally, since it is through it that the infrastructure needs required for a nation's economic and social activities are met. Urban environments are composed of various structures that favor economic, social and any other activities of interest within the existing population; such urban environment is mainly connected by a system that is constituted by asphalt pavements of flexible or rigid type. This project analyzes the environmental impacts generated during the construction process of an asphalt pavement corresponding to the Real de Sevilla III subdivision, located in Obregon City, Sonora, Mexico, applying the Simapro 9.0 Software, obtaining a result of 12.618 Kg CO2 eq/m2 and 1,140, 863.493 Kg-CO2/fractionation generated by its main materials and activities and equipment consumptions.
