PURPOSES : The authors set out to estimate the related carbon emissions, energy use, and costs of the national freeways and highways in Korea. To achieve this goal, a macro-level methodology for estimating those amounts by road type, road structure type, and road life cycle was developed. METHODS : The carbon emissions, energy use, and costs associated with roads vary according to the road type, road structure type, and road life cycle. Therefore, in this study, the road type, road structure type, and road life cycle were classified into two or three categories based on criteria determined by the authors. The unit amounts of carbon emissions and energy use per unit road length by classification were estimated using data gathered from actual road samples. The unit amounts of cost per unit road length by classification were acquired from the standard cost values provided in the 2013 road business manual. The total carbon emissions, energy use, and cost of the national freeways and highways were calculated by multiplying the road length by the corresponding unit amounts. RESULTS: The total carbon emissions, energy use, and costs associated with the national freeways and highways in Korea were estimated by applying the estimated unit amounts and the developed method. CONCLUSIONS: The developed method can be employed in the road planning and design stage when decision makers need to consider the impact of road construction from an environmental and economic point of view.

최근 정부의 미세먼지 특별법이 발효됨에 따라 비상저감조치 시행시 건설현장 및 공장 작업시간을 조정 및 단축하도록 권고하고 있지만 정량적인 기준 및 저감기술 부재로 인해 기업의 자발적 참여를 유도하는 수밖에 없는 실정이다. 또한 최근 도로포장 재료생산 플랜트에서 발생하는 비산먼지 및 유해가스로 인한 피해사례가 다수 발생하고 있으며 이로 인한 공장 주변 주민들과의 갈등이 심각한 실정이다. 이에 본 연구에서는 국내외 도로포장 관련 비산먼지 발생현황 및 관련법에 대한 조사를 수행하고, 도로포장 전주기(생산-시공-운영)에서의 단계별 발생량 조사를 통해 각 단계에 적합한 비산먼지 저감기술 개발 및 적용방안을 제시하고자 한다.
