As a result of a collaborative research programme a software program called asPECT has been developed and maintained by TRL.

asPECT is the output that has been produced as a result of the 2008-11 Collaborative Research Programme. Collaborative research is a joint initiative of the Highways Agency, Mineral Products Association, Refined Bitumen Association and TRL Limited. The project was further endorsed by the Waste & Resources Action Programme and Adept. asPECT provides a methodology to calculate the life cycle greenhouse gas emissions or ‘carbon footprint’ of asphalt used in highways.
