A soil compactor combining oscillation and conventional vibration in a single drum is adding value to in-place recycling projects by slashing the time it takes to get compaction to required density. In northern Michigan, a Hamm H 13i VIO dirt roller — in oscillation mode — was paired with a Wirtgen WR 240i recycler/reclaimer to rebuild Michigan S.R.

On February 27, Linder Industrial Machinery hosted a seminar for customers at "The Farm" in Selma, N.C., featuring industry experts from Wirtgen America. Tim Kowalski, applications support manager of Hamm's compaction division, and Laikram "Nars" Narsingh, commercial support and development manager, led the discussion "Fundamentals of Paving and Compaction" in a classroom format and machines were on display for viewing and questions.

Digitalization, electromobility and globalization are rapidly changing our world – and along with it the construction industry. Nevertheless, rollers will continue to be needed for compacting soil and asphalt in the years to come. The requirements for process efficiency and transparency are expected to increase concurrently.

With the HP series, Hamm is presenting a totally new generation of pneumatic tire rollers. The series is full of technical innovations and advances – especially in relation to the operator's platform, the water and additive sprinkling system as well as the ballasting, according to the manufacturer.

The 1960 census reported that just under 30,000 people lived in Kaufman County. Since then, each subsequent count has increased. The last, in 2010, reported the population at a little more than 103,000 residents. Then, an estimate in 2018 had the total at more than 128,000 people.

Following its successful market launch, cold milling machine specialist Wirtgen is rounding out its new generation of large milling machines at the ConExpo-Con/AGG 2020. The W 250 Fi and W 220 Fi will make their world premiere at the show. The two W 210 Fi and W 207 Fi large milling machines as well as the W 380 CRi cold recycler, exhibited together as a recycling train, will make their North American debut.

The Pennsylvania Department of Transportation (PennDOT) Engineering District 3 continues to work to remedy the challenges created by above average precipitation in north central Pennsylvania. This has occurred since 2016 and has resulted in flooding in many areas.

In the busy phosphate mining district south of Orlando, a two-lane blacktop road all but destroyed by trucks got a new lease on life due to the biggest full-depth recycling (FDR) and asphalt emulsion stabilization project undertaken to date by the Florida Department of Transportation.

At HAMM, the developers are thinking not only about the next machine generation; they also are focussed on the effects that current megatrends will have on road building in general and on compaction in particular. Here the globally leading roller manufacturer is pursuing a holistic approach taking into account the "hardware" aspects, that is to say trends in machine technology, as well as those relating to "software" such as for example questions concerning the role of people in the construction process of the future.

HAMM is presenting innovations in all product segments, including a few world premieres at bauma 2019. The spectrum ranges from a completely new series of pneumatic tyre rollers and the first tandem roller with true split oscillation drums to numerous new options for earthwork compaction.

In the past six months, HAMM AG has been accoladed with two design prizes for its "Autonomous Roller F1", a study on autonomously operating rollers — The international Automotive Brand Contest 2018 jury awarded HAMM the label "Best of Best" and the compaction specialists from Tirschenreuth received the "German Design Award Gold 2019" for their compelling vision of the future.
