Asphalt milling, paving & compaction

In Estonia, Novotrade Invest, which produces hydrocarbon resin HCR-105, has carried out research work on the material that can be used as a bitumen modifier. Hydrocarbon resin HCR-105 is obtained by thermal polymerisation of hydrocarbon fraction C9 [industrially it is isolated from the C9 aromatic hydrocarbon fraction during petroleum distillation].

US and European asphalt paving needs are different, but some firms are bridging that gap, reports Mike Woof. With a clear differentiation between the US and European asphalt paving markets, manufacturers from the latter are now developing machines aimed at the former. The US and European markets for paving machines have developed along very different lines. North American pavers are designed for high throughputs and high paving rates, having been designed to meet a need to build roads over long distances wi

As powerful fabrics, geosynthetics and geotextiles have a wide range of applications in many civil engineering applications including roads and airfields. Geosynthetics specialist Tensar is introducing a radical new product that it thinks will revolutionise the construction industry. According to the company, its new product represents the "biggest advance in ground stabilisation technology for 25 years. Six years in development, it is said to offer major improvements in aggregate confinement and soil stabi

Improved surface quality and improved machine design are key trends in the asphalt paving sector, Mike Woof reports There is a big difference in asphalt paving techniques in North America and Europe. In North America, the need to construct long stretches of highway quickly resulted in wide pavers offering high throughput capacity, with compaction equipment then being used to achieve the required density of the various courses. In Europe's highway construction projects, distances tend to be shorter and contr

Several key highway construction innovations will be unveiled at the Intermat show

In the UK severe winter conditions for the second year in succession have resulted in an increase in the number of pavement surface failures and potholes developing.

A report from Audit Scotland states that it will cost €2.69 billion (£2.25 billion) to correct all the faults on the country's roads.

An agreement worth US$493 million will seal the future or road maintenance projects and highway upgrades in the Philippines.

Brazilian contractor Odebrecht will carry out a major project in Panama City worth US$778 million.

Investigations are in hand in Costa Rica over a series of faults on the highway linking capital San Jose with Caldera.
