Uchehara, I; Hamma-adama, M and Moore, D (2020) Highway sustainability construction: Reducing carbon emissions using process management. In: Scott, L and Neilson, C J (eds.) Proceedings of 36th Annual ARCOM Conference, 7-8 September 2020, Online Event, UK.
Abstract
Highway pavement construction with hot mix asphalt (HMA) emits large quantities of carbon. Accordingly, carbon emissions have become a critical issue in the infrastructure development in specific and construction industry at large. However, to date, the approach to implement low-carbon emission in highway construction appears with speculations. The aim of the study is to conduct a comparative analysis in the use of warm-mix asphalt (WMA), to replace hot mix asphalt. The analytical hierarchy process was used to establish the processes involved in the production to the construction of the HMA and WMA. The weight-density of the carbon was determined to compare the various emission mass of HMA and WMA.The findings identify a reduction in the carbon emission, energy-saving, and cost reduction in the use of WMA during the plant production, and pavement construction. The study is significant in two folds. First, it identifies carbon emission at various stages of production and construction of WMA and HMA. Secondly, it provides bases and approach for future analysis of asphalt materials used in highway construction.

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
