Asphalt milling, paving & compaction

Asphalt paving technology continues to develop, benefiting from new technologies and new diesel engines - Mike Woof reports The asphalt paving equipment market is seeing the introduction of new low emission engines that will meet the Tier 4 Final regulations for Europe and North America. These have required some major engineering changes, with firms now having to install bulky exhaust after-treatment systems and additional cooling for engines and turbos.

The two-way flow of machine data is a crucial issue for machine optimisation and new telematics systems are becoming increasingly important in construction Telematics systems can be tapped into by machine control technologies to allow greater integration of the machine as a data provider within an operation. And for certain production machines that feature wear-intensive operation, telematics systems are becoming a vital tool for minimising maintenance costs by scheduling service intervals, maximising u

The Federal Highway Administration (FHWA) in the United States is offering demonstrations of its Dynatest 6875H Highway Friction Tester (HFT) to state departments of transportation (DOTs). The HFT is a self-contained testing vehicle that maps friction at one-foot intervals continuously along a pavement section. Agencies can use friction data provided by the HFT for both network-level and project-level applications. Continuous friction testing can improve agencies' ability to measure friction through inte
