Asphalt compaction advances were unveiled from an array of manufacturers at the INTERMAT 2012 event - Mike Woof reports. With new emissions legislation being introduced, manufacturers are rolling out a range of new asphalt compaction models designed to meet the latest requirements. These include both large rollers for high-production highway operations and compact machines designed for the rental market and suited to urban applications, with the latter segment becoming particularly competitive at present.
The latest compaction technology offers users the benefits of more accurate performance by combining heat detection and compaction metering with GPS In Europe several leading manufacturers now offer more accurate compaction technology, with Ammann, BOMAG, Dynapac and Hamm all having developed advanced control packages. The technologies vary widely but the advantages are broadly similar, with smart compaction allowing the user a greater degree of control over the compaction process and delivering major reduc
