Chong, D; Wang, Y; Chen, L and Yu, B (2016) Modeling and validation of energy consumption in asphalt mixture production. Journal of Construction Engineering and Management, 142(12): 04016069, ISSN 0733-9364
Abstract
Producing asphalt mixtures for pavement construction is an energy intensive process accompanied with enormous costs and greenhouse gas (GHG) emissions. In this study, a system of integrated thermodynamic models and a software tool were developed for the estimation of energy consumption in asphalt mixture production. The theoretical models were validated through a large amount of data collected from six asphalt mixture plants. This study contributes to construction engineering and management practices by revealing the fundamental heat and mass transfer processes in asphalt mixture production. It enables different asphalt mixture (batch) plants to use the same procedure for the estimation of energy use and the associated costs and emissions. It also helps examine the sensitivity of energy consumption to different influencing factors and offers the opportunity to improve production efficiency.

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
