Researchers at Purdue University in the United States have developed a hydrophobic sealant that could prevent potentially damaging fluids from entering concrete pores. Paul Imbrock, founder and president of Environmental Concrete Products – the university’s spin-off company - said the firm’s Fluid iSoylator product can be used to protect new and existing concrete. "Our product is absorbed into dry concrete's pore network to create a hydrophobic barrier that prevents potentially damaging fluids from en

The Louisiana Transportation Research Center (LTRC) has released a report summarising current US asphalt and concrete pavement smoothness requirements. The report, Best Practices for Achieving and Measuring Pavement Smoothness, A Synthesis of State-of-Practice, is important at a time when the US is undergoing a change in the way smoothness specifications are written. A growing number of states are moving away from profilograph-based smoothness specifications in favor of specifications based on a more widely

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.

Minnich Manufacturing said that its machine-mounted drills are now available with a number of features engineered to increase safety and productivity in dowel-pin drilling applications, and are available in both hydraulic and pneumatic options. Primarily used for full-depth repair, Minnich Manufacturing offers excavator or backhoe or skid steer-mounted units that suit horizontal patchwork jobs with a relatively long distance between the areas to be drilled. Apart from increased portability, the dowel-pin dr

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
