Since launching its Gyratory Compactor B041 in February 2012, Matest has improved on the machine’s design. Changes to worktop, door and lighting – and a novel new accessory to help with weighing the mix - aim to improve the equipment’s functionality. Matest has reduced the size of the Gyratory Compactor’s worktop to make the use, transportation and installation easier when tests are performed on mobile laboratories or directly on construction sites. And it has reshaped the worktop to accommodate the ‘integr

ELE International is launching the Geotechnical Data Acquisition Unit (GDU), a multi-channel data logger which can co-ordinate test data from several different soil tests at the same time. This development means that a wide range of soil tests can be carried out in a very cost effective way, with accurate and reliable results, says ELE. Combining the GDU with the transducers from the various soil tests and ELE’s geotechnical software package DS7, creates a system which can co-ordinate and supervise the vari

UK-based Cooper Research Technology has expanded into the US with the acquisition of James Cox & Sons, of Colfax, California in September 2012, and the appointment of US asphalt expert Dr Geoffrey Rowe as a non-executive director. Cox and Cooper are a good fit culturally. Both firms were founded by inventors – Jim Cox and Keith Cooper – and both are built on strong links with academia: Cox with UC Berkeley and Cooper with NTEC at Nottingham University. “It is the joint intention to be a customer focused bus

UK firm Carbolite has developed a new Asphalt Binder Analyser which it says simplifies and automates calculation of the asphalt binder content of hot mix asphalts (HMAs). Traditional binder content tests use solvents to extract the binder, whereas the ABA 7/35B Asphalt Binder Analyser uses a ‘loss on ignition’ test method. “This avoids the mess and chemical waste disposal issues of traditional solvent extraction based test methods,” said Carbolite’s product manager Alan Street. The ABA 7/35B Asphalt Binder

As the shift towards performance-based pavement design continues, testing equipment manufacturers are responding with new solutions for their customers - Kristina Smith reports. CONTROLS Group is launching a new dedicated asphalt division, PAVELAB SYSTEMS. The move signals a desire on the part of the manufacturer to offer a more partnership-style approach, working with customers to provide them with the right asphalt testing solutions at every stage of a pavement’s design and construction. “The mission of o
