Cifa equipment is pressed into service for Venice’s Mose project

November 25, 2015

The Mose project is a vast intervention plan by Italy’s Ministry of Infrastructure and Transport to protect Venice from flooding. It also has presented Cifa and its partners a big challenge for pumping concrete over a long distance. The work, being carried out by the Venezia Nuova Consortium, consisting of national and local construction and engineering companies, includes four mobile barriers consisting of 78 gates at the lagoon’s inlets. Most of the time the barriers will be resting on the seabed and not

Sustainable road construction: current practices and future concepts

November 23, 2015

The road sector produces the highest level of greenhouse gas, directly, through fossil energy used in mining, transportation, paving works... and indirectly through the emissions coming from vehicles.

A rejuvenator derived from pine trees and natural asphalt

November 20, 2015

This month we look at two additives from natural sources: a rejuvenator derived from pine trees and naturally occurring asphalt - Kristina Smith writes One of the problems experienced with pavements containing RAP is that, although they exhibit good rutting resistance, they often fail early due to fatigue cracking. Biorefiner Arizona Chemical has just unveiled independent test results for its SYLVAROAD RP1000 Performance Additive that it says demonstrate that the rejuvenator can help create mixes that ar

More efficient asphalt output from new plants

November 20, 2015

Advances in asphalt plant design offer major gains in product throughput and quality, while also allowing for warm asphalt and increased recycling The asphalt sector is constantly looking for ways to optimise production, lower costs and improve product quality and consistency. Competition is fierce in the asphalt plant market, with several of the key companies working hard to develop new and more efficient technologies, as well as equipment that is more versatile and more mobile. Advances have been made

Rebuilding better gravel roads more efficiently

October 15, 2015

Using a linear road crusher can rebuild gravel roads using material onsite at a fraction of the cost of conventional methods. Gravel roads are common in many rural areas in the US to provide access to temporary work sites and are also used widely in developing countries. Maintaining and repairing these roads can pose challenges and new methods may offer improvements in efficiency.

Cold recycling helps rebuild of Brazil’s Ayrton Senna highway

September 28, 2015

Brazil’s Ayrton Senna Highway has been rebuilt using cold recycling. Brazil’s SP-070 is also known as the Ayrton Senna Highway and is a major highway in the country, carrying heavy traffic volumes. For its rebuild, the time-saving, cost-efficient and eco-friendly benefits of the cold recycling process have been put to the test. The SP-070 provides a key transport link between São Paulo and Campos do Jordão, Vale do Paraíba and Rio de Janeiro, as well as being the main access route to Guarulhos Interna

Innovations introduced to optimise milling

September 28, 2015

New developments for the milling machine sector should help optimise performance, as well as increase health and safety standards for site personnel Advances in the milling machine market generally focus on new models being available or developments to drums and cutters. However some rather different developments are taking place that could well deliver long-term improvements for health and safety as well as the quality of work carried out, optimising milling operations. Earlier this year, new guideli

Vögele sets paving record in German capital

September 16, 2015

Material transfer vehicles and remixing systems are crucial to delivering quality paving. Using material transfer vehicles (MTVs) can play a major role in delivering high quality road surfaces. These units can help boost quality by minimising the risk of material or thermal segregation. A major road paving project has been carried out in Germany using innovative paving methods. For the first time ever, binder and surface courses were paved over a width of 15.5m. This paving job was carried out on a 4.2km st

New innovations for crushing and screening equipment market

September 16, 2015

Mobile crushing and screening solutions have become a key component for the aggregate production sector - Mike Woof writes. The market for mobile crushing and screening solutions has grown enormously in recent years. With the first track-mounted mobile units having appeared in the 1980s and pioneered by a small number of manufacturers, the range and variety of units on the market has grown enormously since.
