Tavafzadeh Haghi, N; Ahmadian Nezhad Monfared, M; Hashemian, L and Bayat, A (2019) Capital cost comparison of pavements comprised of insulation layers: Case study in Edmonton, Canada. Journal of Construction Engineering and Management, 145(7): 04019038, ISSN 0733-9364
Abstract
Using insulation layers is the go-to strategy for alleviating winter frost heave and subgrade weakening during spring thaw, but the cost effectiveness of using insulation layers compared to conventional methods needs to be evaluated. This study quantifies (in Canadian dollars) the capital cost for construction of roads comprised of insulation layers (bottom ash and polystyrene boards), along with substituting the subgrade material with high-quality granular base course (GBC) material based on a test road in Edmonton, Alberta, Canada.

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
