Recycling

Road construction has evolved considerably in recent years and today more options are available, offering greater longevity and durability, lowered costs, faster application and reduced impact on the environment. The fact that more options are available, however, means that more critical decisions must be made in order to ensure that the optimal solution is selected for the specific needs of each project. In this article we will look at some of the variables that should be considered, while examining the va

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

South Africa takes crumb rubber use to the next level - *Anders Marschall Jensen The preservation of the environment is a global concept, and in the road construction industry, it is all about preservation of roads. In earlier days, roads were built with the primary goal of moving passenger traffic from one place to another, but these days, roads are very different. Not only is there passenger traffic, and more of it, but roads must also deal with extensive movement of products in heavy vehicles. Therefore,

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
