Egypt’s new concrete highway connecting Cairo with Sues

July 15, 2016

CEMEX has played a key role in a highway construction job in Egypt. The company has supplied 130,000m3 of concrete that has been used for the construction of the new Cairo–Suez highway project. The project is of note as this is Egypt’s first concrete highway and if it proves successful, more are likely to be built using this construction method. The 35km road is of major importance to Egypt also as it connects the capital, Cairo, with the seaport city of Suez, two of the nation’s most important economic cen

New concrete testing technologies improve speed, safety and quality

July 8, 2016

Developments in data processing and management are revolutionising the way concrete strengths can be measured and used to improve efficiencies - Kristina Smith reports on two new technologies A new system that uses thermal imaging to measure the strength of sprayed concrete tunnel linings is being trialled for the first time in London. The brainchild of Dr Benoit Jones, managing director of Inbye Engineering, the technique could lead to improvements in safety, quality and – in the longer run – productivi

Fast bridge building in Tennessee

July 5, 2016

The Tennessee Department of Transportation (TDOT) recently completed the Fast Fix 8 bridge project in Nashville, with help from a Power Curbers slipformer belonging to Irwin Concrete Construction. TDOT’s goal was to replace eight ageing interstate bridges along Interstate 40 through Nashville using a process called Accelerated Bridge Construction (ABC). This uses fast-paced, around-the-clock work to limit road closures and speed up bridge completion, impacting surrounding communities as little as possibl

Innovations in concrete paving with new technology

June 22, 2016

The start of 2016 has seen major developments in the concrete paving sector - Mike Woof writes So far in 2016 there have been several major developments in the concrete paving equipment market. Many of the key players have introduced new models, broadening their ranges of machines on offer. US firms continue to dominate this niche area of the construction equipment market, with one European company being the only other major international player. At least two Chinese manufacturers have unveiled concrete

Concrete highway linking Mexico with US

March 17, 2016

A new concrete surface has been constructed along the busy Monterrey-Nuevo Laredo highway in Mexico. This route is of prime importance both for Mexico and its neighbour, the US, as it is the main export-import route between the two countries. Located in northeast Mexico, the Monterrey-Nuevo Laredo highway connects Mexico with the state of Texas in the United States. The route carries 52% of Mexico’s imports and exports and is crucial to the country’s economy, as well as for that of the US. CEMEX Mexic

Novel drilling system from Minnich

March 17, 2016

Minnich Manufacturing has expanded its product range with a series of new models that offer additional capabilities. One of these is a special application drill designed for pinning temporary concrete barriers that separate traffic from work zones. The drill is said to save time and cost by eliminating the need for multiple workers to drill holes by hand. The barrier-mounted drill is designed to ride along the top of the wall and can drill three holes simultaneously. The self-propelled machine runs off a

New compact slipformer widens G&Z range

March 17, 2016

A new and more compact slipform paver is being introduced by Guntert & Zimmerman, widening the firm’s range of models. The company has been known in the past for its large slipform pavers used in road and airport runway jobs but in recent years has developed smaller and more compact units. The S400 shares many of its features with the existing S600, which was previously the most compact model in the line-up. The firm’s German representative, Peter Hedke said, “It’s the smallest machine we’ve ever built.”

Designing for geosynthetics use in construction

March 9, 2016

NAUE is offering its 2016 update to its SecuSlope design software for mechanically stabilised earth (MSE) applications. The SecuSlope 3.0 package is said to be a user-friendly, interactive, design-orientated program for designing geogrid-reinforced slopes, walls, and abutments. Based upon a user’s project-specific inputs, the English language software produces optimal geosynthetic reinforcement layouts based on geogrid type, length and spacing. Factors used by the software include reinforcement strengths, r
