The UK Highways Agency, which maintains Britain“s network of motorways has approved Glasphalt, developed by RMC Aggregates, for use in road surfacing. Glasphalt will provide a use for waste glass and reduce demand for aggregates. The material is made of 30% crushed glass, an alternative to the aggregates normally used in road surfacing. The material is being used on resurfacing work on a three-mile section of the M50 in Gloucestershire (west of England) and the M6 motorway in Cheshire (northwest England). The glass used in the new asphalt product is obtained from bottle banks and the waste handlers used by municipal authorities. The glass is processed at an RMC quarry in Derbyshire (central England) where it is crushed, impurities are removed and it is mixed with limestone and bitumen. Glasphalt provides a use for “stockpile3” green glass waste that has very few end markets, RMC said. According to the company, “Its use reduces disposal of glass at landfill sites and scales down extraction of of primary aggregates”.
