Call for greater use of warm-mix asphalts

摘要

LAST month the All-Party Parliamentary Group (APPG) on Highways issued a report highlighting how the use of warm-mix asphalt (WMA) can reduce carbon emissions and improve efficiencies on highways projects. WMAs are manufactured and laid at lower temperatures than traditional asphalts, using less energy and delivering meaningful carbon savings without compromising performance. Their use can reduce C02 emissions associated with asphalt production for road maintenance and construction projects by around 15%, depending on product and plant. The use of WMAs also improves conditions for the workforce, plus, as less time is required to cool to trafficking temperatures, carriageways can be re-opened earlier - minimizing disruption for road users.
