Warm Mix Asphalt: Pros and Cons of WMA Technology in Paving
Warm mix asphalt (WMA) primarily differs from its hot mix asphalt (HMA) counterpart on the basis of providing for lower asphalt production and compaction temperatures, which can be between 30 to 120ยฐF less than HMA applications. However, WMA offers a number of key advantages over traditional HMAs beyond temperature reduction.ย ย ย While WMAs are no longer uncommon across the paving [...]
