A Study on an Environmental-Load Analysis for Airport Pavement

In this study, the LCA analysis technique, which quantitatively calculates the environmental load from the entire life cycle, is used to assess the environmental load of the airport pavement and the method to reduce the environmental load is suggested. The LCA analysis is conducted for the entire life cycle of the airport pavement to quantitatively determine the environmental load in six categories of the Environmental Product Declaration. The LCA analysis results show that 98.4% of the total environmental load of the airport pavement is generated from the global warming category. accounts for 88.24% of the total emission: 38.03% in the initial construction stage, 61.96% in the maintenance stage, and 0.01% in the demolition stage. To reduce the emission level of the wide parallel pavement method that is mostly used in these days, the warm mix asphalt is applied to some sections in airport pavements, and the capacity of dump trucks is changed. The suggested reduction plan is also applied to actual cases, and its reduction effect is verified via the LCA analysis.
