In order to prepare a plan to improve the inspection standards of asphalt plants, the ‘Asphalt plant checklist’ included in MOLIT’s ‘Construction Work Quality Management Business Guidelines’ was reviewed. It was compared with the related standards of asphalt plants, and the following conclusions were obtained. For effective inspection of asphalt plants, it is necessary to prepare standards in consideration of production products such as SMA, porous asphalt mixtures in addition to dense-graded asphalt mixtures. In the material quality inspection, it is necessary to revise the standards that is difficult to apply, such as the once-a-day sieve test for cold-bin aggregates and once-a-month asphalt quality test for plants. It is necessary to check the lab and job-mix design and check it as a test production to check the suitability of production management. It is also necessary to prepare an inspection management system for asphalt plants to conduct joint inspections, and to increase efficiency by using the inspection results for approval of other sites.
