AN INNOVATIVE slurry wall solution has been used by Bachy Soletanche at the Alderley Edge By-Pass project in the UK. Bachy Soletanche provided assistance for the A34 Alderley Edge by-pass project in the UK being carried out by main contractor Birse Civils. This solution was required to tackle challenges posed by the water table at the Welsh Row section. Bachy Soletanche used its experience with slurry cut-off walls, a technique rarely used in Britain on road construction, to benefit a tricky section of the

Huge highway developments are being planned and carried out to further improve East-West transport, with Central Asia a key region as Patrick Smith reports History was made in late 2010, when one of the biggest road building projects ever envisaged in Eastern Europe was given the green-light. It was the occasion when Russian president Dmitry Medvedev signed a law that would allow his country to build its segment of a huge highway around the Black Sea. The idea is to complete the 7,140km highway, wi

Since 1908, the World Road Congress has been the premier international event for roads and road transport. The XXIVth edition held in the Mexican capital Mexico City (26-30 September, 2011), is organised by the World Road Association (PIARC/AIPCR) together with SCT; AMIVTAC (Asociación Mexicana de Ingeniería de Vías Terrestres) and Vivir Mejor, will present current research and best practice, provide a venue for discussion of advances in technology and practice and bring together road transport stakehold

BICES 2011 equipment exhibition attracted unprecedented levels of visitors, according to the organisers. With China's construction market booming and the world's largest infrastructure investment programme in full swing, the country is seeing a huge growth in demand for new machines. Manufacturers from inside the country as well as international firms are keen to boost sales in the country and develop market shares. As a result, promotion is a key issue and all manufacturers, Chinese and international, are

When Dubai Airport contacted Waterblasting Technologies it faced a number of challenges. One was finding a waterblasting system that would operate successfully in the 42º-52ºC daylight heat of the summer and also to find the fastest and most productive waterblasting system because of very limited runway closure time. Chemicals, shotblasting and other waterblasting equipment had been tried on the runways, but eventually engineers and management chose the Stripe Hog SH8000T manufactured by Waterblasting Tech

Spanning Manahawkin Bay, and carrying traffic along Route 72 between Long Beach Island and Manahawkin, New Jersey, USA, the Dorland J. Henderson Memorial Bridge, known as the Manahawkin Bay Bridge, was in need of repair. New Jersey Department of Transportation (NJDOT) specified Transpo T-17 MMA polymer concrete patch and T-18 MMA polymer concrete slurry overlay as approved materials for the 12,000m² bridge rehabilitation project on the steel girder bridge. All the bridge deck spalls were prepared and patche

Marini has been involved for some years in supplying asphalt plants to Indian companies involved in road and airport construction programmes. Through Marini India, the Fayat Group company installed what it claims is India's "greenest asphalt plant" for Navayuga Engineering Company, which chose a Marini MAC plant for work on the PPP Armur-Adloor Yellareddy road project on the Nagpur-Hyderabad section in central India. Marini says that its new generation of energy-efficient asphalt plants has been devel

With the Tier 4 interim/Stage IIIB emissions requirements due next year, further upgrades will be required for all wheeled loaders sold in Europe and North America. In the mean time manufacturers are focussing on improvements that cut cycle times, boost productivity and reduce downtime for example. From Doosan comes the DL420 wheeled loader, which takes over from the previous DL400 and is aimed at use in a range of materials-handling work. The DL420 features a 4m3 bucket and is a 22.3tonne machine that

New regulations and technology are driving change in the soil compaction sector - Mike Woof reports. The impact of the Tier 4 Interim/Stage IIIB emissions regulations has been hard on some machine sectors in particular. Sloping engine covers have been introduced in several equipment categories as a way of improving visibility for operators, including soil compaction machines. At the same time, new machine guidance technologies have been developed and introduced to the soil compaction market, boosting produc
