Asphalt milling, paving & compaction

Among European countries, France consumed the most bitumen in 2016, using over 2.2 million tonnes of the black stuff, according to figures from Eurobitume. The recent 2016 Eurobitume Bitumen Consumption Statistics for Europe shows that bitumen consumption across all grades for Europe as a whole was 11,274 million tonnes in 2016.

While not required for its Sacramento Airport contract, Granite Construction* is getting to grips with IC specifications thanks to Volvo CE’s Compact Assist. In the US, 23 states have written intelligent compaction (IC) specifications for asphalt paving jobs and more states are expected to follow. Among those states with IC specs is California.

A Spanish contractor has utilised an asphalt plant from Ammann to deliver high-quality material for a key runway at Barcelona Airport. The firm Benito Arnó e Hijos, won the deal to provide asphalt for the reconstruction of the main runway at Barcelona-El Prat Airport. The firm opted to use an Ammann ABT 280 SpeedyBatch plant for the project as this model offered the combination of both mobility and productivity as required. With the short-term nature of the project, a fixed plant would have been unsuitable

A new system from MOBA Mobile Automation allows for accurate measurements to be made of pavement thickness. Called PAVE-TM, the system can capture the installation thickness of any road layer during asphalt paving and uses contact-free measurement technology. Layer thickness is a key quality feature in asphalt paving and the PAVE-TM system can help improve process reliability by eliminating errors that occur with manual measurements and also allow savings on materials costs.

Techniques can help in preventing cracks in underlying layers from penetrating to new surface layers - *Farzad Tooryani. For road repairs involving milling off worn asphalt surface layers before repaving, the use of crack sealing is a crucial task. This can help to prevent full reflection of existing cracks from underneath layers into the new wearing course. Once the milling work is complete, locating existing cracks is a crucial task for the site supervisor. Efficient routing equipment that is easy to hand
