Impact of curing time on warm mix asphalt short-term performance
The emerging use of warm mix asphalt (WMA) technology has led to economic and environmental benefits for transportation agencies and road users. Among these benefits is the reduced mixing and compaction temperatures of WMA. However, decreased temperatures may affect the resulting complex modulus to …
