PURPOSES : The objective of this study is to evaluate the effectiveness of spraying dust suppressants in relation to the condition of road pavement in South Korea and to develop an optimal management method by continuously measuring re-suspended dust concentrations using a vehicle-based measurement.
METHODS : Indoor experiments were conducted to select suppressants suitable for local conditions to reduce reducing road dust, which were identified through literature review. Data collection followed the evaluation method by selecting a section sprayed with dust suppressants and a non-sprayed section within the service road.
RESULTS : The BPT experiment is designed to ensure the skid resistance of the road when dust suppressants are sprayed on the road. The Environmental toxic tests for PM10, HCHO, and TVOC all met the daily indoor air quality standards recommended in Korea for determining stability. Comparison of PM10 contents before and after spraying of the test road with dust suppressants and the non-sprayed section, it was confirmed that the dust suspended by the external environment may be reduced, but the amount of dust remaining on the road may increase. After 4 hours, when the water had evaporated, the dust suppressants remained effective and lasted for two-days.
CONCLUSIONS : The concentration of fine dust in South Korea varies with the average duration of highly concentrated fine dust being 26.5 h nationwide, 20.5 h in the Seoul metropolitan area, and 25.1 h in Gyeonggi-province, suggesting a duration of one to two days. Thus, the fine dust problem can be solved by using dust suppressants.
