Pavers produce on Chinese road building project
May 19, 2015
Volvo tracked pavers are helping China meet its ambitious programme of building 10,000km of roads annually. China’s ambitious road building programme is seeing over 10,000km of new highway being completed every year. Productivity, reliability and good uptime of equipment are key to this programme being achieved. And to the north of Xi’an, four Volvo Construction Equipment (Volvo CE) ABG8820 tracked pavers recently worked 14 hours/day paving the final layer of asphalt on a new highway. This 96km route opened
Secmair launches Multispray bar for dual purpose spreading duties
May 18, 2015
Surface dressing of highways is a demanding precision process where speed and accuracy is paramount. Secmair, part of the Fayat Group, has launched its Multispray spraybar to ensure the speed rate and application of binders and additives are perfect. This spraybar combines two rows of jets that can allow two spread rates across the width of the roadway, meaning the carriageway and hard shoulder can be coated with different mixes. This can eliminate or prevent the phenomenon of bleeding. One row can be

AAPA endorses fatigue endurance limits AUSTROADS guidelines
May 18, 2015
The Australian Asphalt Pavement Association (AAPA) has endorsed the new concept of a fatigue endurance limit to determine the full depth asphalt pavement thickness in a freeway environment. The endorsement came from the first meeting of the AAPA’s recently appointed National Leadership and Technology Committee (NTLC) made up of senior managers in the pavement and surface technology sector. The NTLC endorsed the industry-prepared draft design guide addendum for Perpetual Pavements from AUSTROADS. AUSTR
Arizona Chemical study reveals lower CO2 footprint with RAP additive
May 18, 2015
A life-cycle assessment has found that an asphalt mix containing a high percentage of reclaimed asphalt pavement (RAP) along with an additive by Arizona Chemical can produce a significantly lower carbon footprint than virgin asphalt mix or a mix containing a low percentage of RAP. The assessment study was carried out by third party Arthur D. Little, an international management consulting firm, using Arizona Chemical’s SYLVAROAD RP 1000 performance additive. The work noted that cradle-to-gate, a road aspha

Investing in road transport boost economies
April 30, 2015
Transport investment faces a shortfall that can perhaps never be breached – David Arminas writes There “will never be sufficient funds for all planned road activities,” said Ben Gericke, transport specialist at The World Bank. The road maintenance industry is going to have to use the best possible contract strategy to win the investment it needs. Speaking at the PPRS Paris 2015 Pavement Preservation and Recycling Summit, Gericke said that the best way for the global highway construction and road maint
PPRS event highlights transport investment shortfall
April 30, 2015
The PPRS event in Paris highlighted the need for additional investment in road transportation – David Arminas writes. Consider the global road network. An improved road from one rural African town to another can reduce the journey time from a one-day walk to a one-hour drive. This could save lives through access to a hospital; allow small businesses to work faster by getting in supplies more quickly; allow children to attend a better equipped school. Roads affect society by allowing healthier and bett
Dynatest’s FastFWD8002 deflectomer picks up more points per hour
April 28, 2015
Pavement engineering specialist Dynatest has improved its best-selling falling weight deflectometer, allowing it to not just collect more data, but collect it faster. The Danish company said its FastFWD8002, which was unveiled at the Transportation Research Board annual meeting in Washington in January, is five times faster than the previous model. The FastFWD8002 collects 75% more test points per hour, meaning it can have around 45% less traffic exposure. The previous unit is upgradeable to FastFWD80
