The demand for road construction material research and testing services in Kenya is expected to soar. The East African country is going through a construction boom, despite policy and financial challenges facing public institutions overseeing the research and testing operations in the transport industry. “Kenya is going through a construction boom and so is the demand for construction material testing services,” said Juma Ali Madzitsa, Geotechnical Lab Supervisor at SGS Kenya, a subsidiary of Swiss based in

The Roadtec RT-500 is a mobile trailer that can be pulled and fed by a Roadtec RX-900 milling machine for cold in-place recycling. But it also can be set up on site as a central cold-mix plant, according to the company, based in the US state of Tennessee. The machine features closed loop sizing with an on-board vibratory screen and horizontal shaft impact crusher. The process is designed to prevent having to pre-process RAP when the RT-500 is used as a cold-mix plant. The RT-500 also has a weigh bridge on b

A variety of issues affect accurate continuous level measurement inside cement plants. The most critical concerns are dust, heavy build-ups, low-reflective media and uneven surfaces in conical and/or air-injected silos with internal objects. Now, new frequency-modulated continuous-wave – FMCW - radar technology, combined with high signal dynamics, offers a way to accurately and reliably measure product levels.

EvoQuip, the newest division of Terex Corporation, is launching a Cobra 230 impact crusher later this year, to sit alongside the Cobra 260. The 24tonne machine will offer a production capacity of 140-150tonnes/hour in asphalt and construction recycling. The Cobra 230 is 11.3m long and 2.46m wide, or 5.15m wide with a side conveyor. It features a quick set-up time and the machine can be moved onsite without having to stop the crusher. Keestrack says that its novel H4 tracked cone crusher is light and compact

German building materials producer HeidelbergCement and Aachen2222 University of Applied Sciences are investigating the absorption of CO² from flue gas by olivine and basalt. The carbonised minerals could be used as a value-added additive in the production of building materials.

Astec Industries is now offering its Silobot inspection service for materials storage silos. The Silobot is a sophisticated tool that Astec’s parts department can use to carry out thorough visual inspection and metal thickness testing inside hot mix storage silos. The remote control capabilities of the Silobot inspection device ensure that personnel stay out of the confined space of the silos. The firm says that the unit can carry out inspections quicker, safer, and more thoroughly. The inspection record pr

US demand for asphalt for use in paving roads and highways looks set to grow and will reach 13.7 million tonnes/year by 2021.
