Contractor Tarmac has carried out major works on the UK’s M5 motorway after recycling around 30,000tonnes of concrete and providing 8,000m3 of new concrete for new slip-form central barrier works. The project, between Junctions 3 and 4a of the M5, was delivered as part of an eight-week scheme to install 13km of new concrete safety barrier. Approximately 30,000 tonnes of concrete were excavated and then crushed into Type 1 and 6F5 aggregates at Tarmac’s recycling site in Ettingshall, Wolverhampton. Over 14,0

This also applies to the Keestrack R8 top crusher unit (former Destroyer 1313), that is presented as a highly productive mobile solution in the output range of 450tonnes/hour.

Mexico-based Grupo Pinfra was one of the country's first aggregate producers to invest in mobile crushing and screening equipment. Twenty years on, the company is still confident that mobile equipment is key to meeting demand and has just expanded its fleet.
In 1991, Pinfra took delivery of two Metso Minerals Lokotrack LT125 mobile crushers and these have now clocked up 30,000 working hours. Nonetheless, there is still plenty of life in these machines and while the newly acquired LT140 jaw crusher takes
