Perera, B A K S and Shandraseharan, A (2023) A framework for aggregate base course waste control in road construction projects. International Journal of Construction Management, 23(6), pp. 1009-1020. ISSN 1562-3599
Abstract
The management of Aggregate Base Course (ABC) wastage in road construction (RC) is an under researched area. Thus, the aim of this study was to develop a framework for ABC waste control in RC projects. The study used a mixed approach consisting of 15 expert interviews and a questionnaire survey conducted among 137 experts engaged in RC projects. The collected empirical data were analyzed using manual content analysis and the weighted mean rank, respectively. The findings of the study revealed that the most significant cause of ABC wastage in RC projects is laying ABC without construction shoulders. The most significant consequence of ABC wastage in RC projects is cost overruns. The most significant measure that can be adopted to control ABC wastage in RC projects is improved transportation of the materials. A framework also was developed in the study to help control ABC wastage in RC projects.

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
