Hydrated lime in asphalt mix designs can improve moisture resistance, improve ageing resistance and enhance stiffness which in combination lead to more durable asphalts. Recognised for decades as beneficial for airport ‘Marshall’ asphalt mix designs and also already included in the specification options for highways asphalts, hydrated lime is nothing new. The durability enhancement having been evidenced internationally to deliver up to 25% improvement in service life seems to be an opportunity to reduce whole life carbon footprints, reduce whole life costs and reduce inconvenience to road users, with low risk.

Note: The name of the British Lime Association (BLA) has changed to ‘MPA Lime’. BLA has been part of the Mineral Products Association (MPA) since 2009 though did, until this year, retain the BLA name.
