Guntert & Zimmerman equipment is being used to create a new hard-wearing asphalt surface on a key Interstate highway in the US state of Kansas as Mike Woof reports A busy Interstate highway in the US is now benefiting from a new, long-lasting surface. The road, Interstate 70 in Western Kansas, was in need of resurfacing. The full-depth asphalt roadway, up to 508mm thick in certain sections, had reached the end of its working life.

Troxler Electronic Laboratories is celebrating 50 years of providing services to the highway industry. In this half-century, Troxler says it has been awarded over 100 patents by the US Patent Office for innovative products that have improved or created many of the new technologies used today in the construction industry. The company is originally known for its nuclear moisture density gauges, but it also provides non-nuclear electromagnetic density devices as well as Superpave gyratory compactors, asphalt i

Specialist equipment is available for carrying out a variety of important tests on asphalt It is important to know how asphalt will react to various conditions such as heat, cold and traffic loads when it is laid on roads. Project specifications will give detailed criteria of what is required, and companies will either ask outside laboratories to make sure the material meets the specs, or will often carry out such tests themselves with trained staff in an on-site laboratory. This will be equipped with the
