Italian firm Indeco is now offering a novel compressor system that can be mounted on an excavator being used with a breaker in tunnelling operations.

Stringless concrete paving systems are easy to use for contractors - Daniel C Brown. With just a few days of training, Hawkins Construction is now up and running with stringless concrete paving technology. This year Hawkins started using the stringless technology on two Interstate highway paving projects, with a total contract value of US$78 million. The projects were on I-80 between Omaha and Lincoln, Nebraska and the first section was for a 9.25km, 18.3m wide stretch of 330mm thick concrete pavement.

A Power Curbers 5700C machine is being used underground in Turkey to slipform the U-shaped concrete platforms on the walls of a new tunnel project.

HTS now offers a sophisticated vehicle identity recognition (VIR) package, which offers key benefits over basic LPR technology. The VIR patentpending technology provides a comprehensive profile of each car including make, model, colour, country or state name and special plate icons.

BASF claims that its latest innovation will help improve efficiency in tunnel construction operations. Developed by BASF's Construction Chemicals division the new Crystal Speed Hardening system (CSH) is an advanced admixture technology aimed directly at the tunneling market.

Blastcrete Equipment Company says that its novel new Mason Mate system provides an innovative solution for concrete repair and shotcreting in tunnelling applications.

Manufacturers are producing innovative asphalt equipment, and operators are benefiting from this as Patrick Smithreports. Asphalt plant manufacturers and operators are understandably placing great emphasis on higher productivity but with lower costs. At the same time they are aware of environmental issues and the ever-increasing use of recycled material in mixes.

PAVING CONTROL specialist MOBA is offering a new system said to be able to boost surface quality and longevity. Called the PAVE-IR, this unit can be used to identify segregation issues during paving processes, a problem that is a major cause of premature failure in asphalt roads. Numerous studies have identified the relationship between thermal segregation and density and the new PAVE-IR package from MOBA is said to offer contractors a non-destructive method for detecting thermal segregation in real time
