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.
