Concrete milling, paving & compaction

Florida’s Fort Lauderdale- Hollywood International Airport (FLL) is now benefiting from an upgraded runway. A key portion of the work has been carried out using equipment from Minnich. The airport handles about 23 million passengers/year and with about 3 million of those from international flights, there was a need to develop the facility to cope with the larger aircraft used on international flights. The Broward County Aviation Department was responsible for the work and specified that the runway exp

Internationally, airports are being upgraded and expanded to increase capacity and safety – Mike Woof writes. All around the world, airports are being expanded and upgraded, both to cope with massive increases in passenger numbers and also to handle larger aircraft. Runways have to be rebuilt with stronger structures and surfaces to handle greater air traffic volumes as well as increased loads from larger aeroplanes. Building airport runways, however, poses many challenges for construction crews. Paving qua

A contractor in the US is now using a piece of equipment for a specific application on a project at Dallas Fort Worth (DFW) Airport. The job required equipment able to deliver high quality to meet tough client requirements, so the contractor decided to use s 255CD Triple Roller Tube Paver from Allen Engineering.

In the US state of Arkansas, a key stretch of concrete roads has been improved, allowing it to cope with current traffic volumes.

Contractor Balfour Beatty Mott MacDonald has used Klaruw’s advanced longitudinal grooving system, GrooveTex, to retexture sections of concrete surface on the M20 in the UK. The GrooveTex system improves and restores surface skid resistance by creating micro longitudinal grooves using closely spaced diamond-tipped saw blades at a predetermined width and depth. While being based on proven diamond-grinding techniques, Klaruw’s system is said to be optimised to provide significant improvements.

New concrete paving machines offer greater versatility as well as performance – Mike Woof writes GOMACO said that its Next Generation Commander III paver has been designed to increase safety and all-round visibility, while offering improved performance. This four track paver benefits from the firm’s latest G+ Connect technology as well as 3D guidance options. A key to the improved performance is the G+ control system while the machine also has power from a quiet, low-emission Tier 4 engine. Fuel consumption

This month we look at two new methods which are allowing concrete to be tested on the spot, and [over the page] we catch up on the latest news from concrete testing equipment suppliers - Kristina Smith writes Sometimes test results can be very bad news. If the concrete pavement or bridge abutment has already been poured, and if the concrete does not meet the specification, the outcome could be very expensive remedial work.

An array of new bridge refurbishment and repair solutions are available – Mike Woof writes Around the world there are many bridges requiring repairs or refurbishment, and there is a ready market for novel solutions to upgrade existing structures. New developments offer quicker and more efficient ways to improve bridge surfaces and structural performance and add new life to ageing designs. Spancrete is broadening the availability of its novel precast building solutions worldwide by offering these to th

Fast repair of Cairo’s busy urban highway has been achieved using paving equipment. And MOBA levelling technology played an important role in ensuring finish quality met requirements. Cairo is Egypt’s fast-growing capital city, with an estimated population of around 20 million living in its catchment area. The city’s fast growth rate however has placed enormous demands on its infrastructure, with transportation creaking under the strain. An increasing numbers of people use the roads in and around Cairo ev
