Asphalt milling, paving & compaction

Bolivia’s new highway will provide better access into mountain areas – Mauro Nogarin writes At the beginning of 2015, work began on the construction and paving for the Tupiza - Atocha - Uyuni highway project. The route is located in Bolivia’s Potosí department: it is 189m in length and forms part of the Southwest Basic Road Network (RVF) of Bolivia.

Huge numbers of construction machines as well as plant and equipment are working overtime, backed by mammoth manpower, to meet the targeted completion deadline of March 2018 for India’s Eastern Peripheral Expressway (EPE). The 135km arterial route is being built with six lanes and surrounds India’s National Capital, Delhi, its National Capital Region (NCR) and the industrially developed North Indian states of Haryana and Uttar Pradesh.

The demand for road construction material research and testing services in Kenya is expected to soar. The East African country is going through a construction boom, despite policy and financial challenges facing public institutions overseeing the research and testing operations in the transport industry. “Kenya is going through a construction boom and so is the demand for construction material testing services,” said Juma Ali Madzitsa, Geotechnical Lab Supervisor at SGS Kenya, a subsidiary of Swiss based in

Aidan Conway, founder of Thermal Road Repairs, the UK manufacture of paver-mounted pavement heaters, explains how the latest version operates. The equipment, which allows asphalt to be laid seamlessly, eliminates joints from the outset. The latest version of the paver-mounted pavement heater from Thermal Road Repairs includes start-stop technology. This allows the computerised equipment to operate independently while synchronising with the paver. In TRR’s original system this was a manual process, explains

Huesker, an earthworks and foundation designer for roads and pavements, has posted a short video explaining “interaction flexibility”, a new term for geogrid-reinforced structures. Interaction flexibility is an important technical term, as important as tensile strength and tensile stiffness, to secure the quality of a geogrid reinforced construction, explains the engineering team at Huesker which has its head office in Gescher, Germany.

The first few months of 2017 have seen a flurry of new model introductions in the asphalt paving sector for both European and North American paving types - Mike Woof writes. Developments are being seen in both European and North American asphalt paving machines. The latest equipment will help boost productivity and quality for asphalt paving work, while many of the new machines also offer increased versatility. Innovations in telematics meanwhile are helping to ensure that new generation asphalt pavers also

The latest developments in asphalt compaction equipment will help boost productivity and finish quality. The new generation compactors can utilise the latest generation machine control tools to deliver quality within the short timeframe determined by the asphalt temperature. Ammann has broadened its asphalt compaction range with the addition of the new ARP 95 K pivot-steer roller and the articulated ARX 90 and ARX 26 models. These units are available with Ammann’s proprietary ACE compaction systems to optim

New technologies and more efficient have also been developed for slurry sealing applications. Bergkamp is introducing the M310CS truck-mounted slurry seal and micro surfacing paver, with power coming from its Tier 4 emissions compliant truck engine. With PTO-driven hydraulic pumps, the M310CS has eliminated the need for a side engine. This reduces exhaust emissions, noise and vibration. The M310CS is features the sophisticated electronic mix control and diagnostic (EMCAD) system, which is designed to manage

Within years, one in six UK local roads will need repairs or face closure, according to the latest Annual Local Authority Road Maintenance – ALARM – survey. The cumulative effect of an ageing network, decades of underfunding, increased traffic and wetter winters has led to around 17% of all UK local roads reportedly in poor structural condition, with less than five years of life remaining. The 22nd annual ALARM survey is a comprehensive study into local road maintenance funding and conditions. Local authori
