Laboratory evaluation of WMA mixture for use in airport pavement rehabilitation

摘要: Abstract The concept of warm mix asphalt (WMA) gives a promise for rehabilitating airport pavement to realize quick turnover traffic after construction, however, laboratory and field data in terms the performance-related properties are significantly lacking using WMA airfield Japan. To fill this gap, three mixtures (different gradations) were systematically investigated compared with conventional used hot (HMA) through series tests wheel tracking test, submerged raveling static bending fatigue test. These made at two production temperatures (30 50 °С lower than normal, respectively) by incorporating commercially sold additive. Results showed that overall, mixture coarse gradation produced temperature 30 °С normal exhibited comparable performance control HMA mixture, it was further recommended use rehabilitation.
