Intelligent Compaction

Granite Construction prepares for the new norm, hitting 100 percent bonus along the way Currently, 23 states have written intelligent compaction (IC) specifications for asphalt paving jobs, and that number is only expected to grow. Among those states with IC specs is California. As with many of the states, however, although they’ve invested time and […]

While they tackled placing large Tier 4 engines, after-treatment systems and diesel exhaust fluid tanks in machines for the January 2017 deadline, asphalt industry OEMs (original equipment manufacturers) saw problems with visibility creeping into design. They worked to solve those challenges to create an environment that is both safe and smart from the operator’s point of […]

As stated by R. Bruce Noel at the 1977 annual meeting of the Association of Asphalt Paving Technologists (AAPT), “The single most important construction control that will provide for long-term serviceability is compaction.” When compaction is enhanced, in-place density can be optimized, thereby improving durability and extending pavement service life. A review of several past […]

As mentioned earlier in this issue, it feels as though World of Asphalt 2016 (WOA) took place ages ago. Yet we have continued uses, of course, for the innovations that were launched at that trade show and in the months following the show. The big topic the past few years has been the slow march […]

On a rural highway in central California, a new-design material transfer vehicle was instrumental in providing a smooth asphalt pavement. The Caltrans pilot project in October 2015 demonstrated an MTV and asphalt intelligent compaction (IC) system on a two-lane highway in San Benito County. The roadway was S.R. 25 near Tres Pinos, about 95 miles […]

OEMs hope new IC technology can replace assurance testing in the construction of asphalt pavements More than mere lines on a touchscreen, intelligent compaction (IC) systems have evolved during the past few years to something that involves complex software and equations working “behind the scenes” while the roller operator works with what she can see […]
