- Abstract
- PURPOSES: This study aimed to analyze economic effect of recycled aggregate production on job-site airport pavement.
METHODS: The validation of site recycling for waste concrete as economic efficiency is analyzed through the case study of site recycling atan O airport pavement construction. The break-even point for the cost of site recycling was estimated according to two different waste concreteprocessing methods such as job-site recycling and processing on commission (or plant).
RESULTS: Job-site recycling cost decreases as the use rate of job-site recycled concrete aggregate increases, or the amount of concrete wasteincreases, but transporting distance decreases. It was shown in an O airport case that as the use rate of job-site recycled concrete aggregateexceeds 61.4 %, the job-site recycling cost is cheaper than the processing cost on commission.
CONCLUSIONS : The results of this study can utilize basic data of feasibility for site recycling of waste concrete on airport pavementconstruction.
