Aim: To maximise value generation and reuse of airport derived construction and demolition waste in the construction of the car park.
Description: OCL’s design replaced the original 15,000t of primary (quarried) Type 1 and 10,000t of primary (hot) asphalt with 8,200t of HBM (hydraulically bound material which s made from recycled aggregates) and 4,800t of OCL’s cold-lay, low energy FoambaseTM Asphalt, so avoided 4,100t of landfill and 4,100t of importation traffic and virgin material. The asphalt side alone saved 370,400 kg of CO2 in production not taking into the account the reduced traffic movements.
