Abstract
Greenhouse gas (GRG) emissions are an important primary criteria for environmental evaluation. As a project evaluation criterion, this study developed a framework that could estimate GHG emissions in asphalt pavement construction based on the limited information available in the feasibility study phase. A thorough literature review and in-depth interviews with domain experts in the field of road engineering were conducted to identify the input variables for this framework. By considering the characteristics of the input variables, such as material type, geometric shape of the structure, and earthwork quantities, an artificial neural network and a parametric calculation were used to develop the framework for estimating GHG emissions. When applied to real-life asphalt pavement projects in the Republic of Korea, the framework produced an average estimation error of 11.2%, which was considered sufficiently accurate for the planning phase. The proposed framework is expected to help decision makers easily evaluate the GHG emission potential of asphalt pavement projects in their preliminary phase such that project viability and priority can be determined in a more holistic manner.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
