Recycling

Brussels calls for 70% recycling of construction waste by 2020 but *Peter Craven asks if there is a greater target to be achieved in the UK. In the UK, over 90 million tonnes of construction, demolition and ground excavation (CD&E) waste is generated each year from construction, demolition and civil engineering projects. Across Europe this figure is well in excess of 1000 million tonnes and represents a valuable and sustainable asset to the construction sector, as well as protecting natural resources. The r

Maintenance of roads in historic districts is a challenge for communities around the world. The sanctity of the surroundings limits the amount of re-engineering and widening that can be considered. Improvement options typically are limited to repairs. Yet repairs also have an impact. The historic areas usually attract tourists and their crucial economic contributions. If the street repairs create too much of an inconvenience, tourists are likely to avoid the area and a negative economic impact and a loss of

Productivity and profitability mean more than how many metres per minute your cold planer mills. In today’s world, precision is every bit as important as pace. Precision eliminates costly rework. It ensures crews don’t remove excess materials, and incur the associated costs in fuel, hauling and machine life. Precision also impacts the entire life—and cost—of a project by creating the proper foundation on which all subsequent work occurs. Cat® Grade and Slope for cold planers helps deliver that precision.

New technologies allow efficient use of recycled asphalt - Mike Woof writes The Eurobitume/Euroasphalt 2012 event in Istanbul earlier this year proved an important event with regard to asphalt recycling innovations. Key developments in this technology were announced, particularly in the field of asphalt production. One of the notable papers came from E-MAK, part of the Turkish Simge Group, which focused on its RATEK system. This technology is designed to use recycled asphalt and can produce greater throughp

New infrared asphalt restoration technologies, such as the Patriot system, are more reliable than before and offer cost benefits over time-consuming, cut-and-fill asphalt repairs. This technology offers benefits over conventional repairs which leave seams that can allow water penetration. Where thes eams are not watertight, the repaired, filled-in portion can fail within a year or so, however infrared technology blends the new asphalt with the old by heating an area 152-203mm beyond the perimeter of the rep

A Dynapac PL350T cold planer helped carry out critical demarcation work on the roads used for the famous Isle of Man's TT motorcycle races. It was used to remove the road markings on the isle in the Irish Sea in readiness for the races. The Dynapac machine is equipped with a special micro milling drum which contains 117 bits, compared to the standard 38, spaced at intervals of 3mm as opposed to the conventional 12mm. In addition, to avoid a sharp edge at the sides of the demarcation area, the drum is slight

A sophisticated pothole repair machine is to benefit from the latest satellite tracking technology from Masternaut Three X. The DP Road Patcher is part of a fleet of plant and vehicles operated by DP Cold Planing, one of the UK's leading specialist highway maintenance companies. DP Cold Planing is now using the Masternaut Three X web-based vehicle tracking solution to improve the management of its large fleet of Mercedes, Scania, JCB and Wirtgen vehicles and plant. This will make the DP Road Patcher even mo
