Method-based learning: A case in the asphalt construction industry

Traditional working practices in the construction industry rely heavily on the onsite experience and craftsmanship (the tacit knowledge) of operators and teams. This results in implicit learning and lengthy learning cycles. The aims of the research are to develop a deeper insight into construction processes and to instigate a change from current implicit learning to explicit method-based learning. To change to explicit method-based learning, Kolb's experiential learning model was introduced into current practices and 'explicating the process' was added to this learning cycle. Further 'reflective observation' and 'abstract conceptualization' were incorporated explicitly during an actual road construction project using feedback sessions with an asphalting team. The adopted learning framework was found to be applicable and useful in the quest for enhanced learning capabilities and improved process control. Fusing Kolb's learning model with onsite collected data was vital in explicating tacit knowledge and implicit processes. The approach enabled a meaningful discussion with operators to unravel their intentions and reasoning behind the chosen strategies. Explicit method-based learning, as here, leads to improved quality awareness, better understanding of the processes and their interdependencies, and improved communication with and within the asphalting team.
