Efficient processing of RAP in the mix
December 19, 2017
There are important methods aimed at the reuse and recycling of reclaimed asphalt pavement (RAP) a number of problems have to be solved however, mainly concerning the elimination of moisture content and how best to heat the RAP without damaging the binder. When RAP is used in percentages of up to 30-40% of the final mix, heating can be carried out through direct contact with hot aggregates. On the other hand, in order to use higher RAP percentages, up to 100%, the plant has to be fitted with a specific h
Faster and more efficient earthmoving with machine control
December 19, 2017
The use of sophisticated machine control tools from Trimble has helped US contractor Beaver Excavating deliver a project more efficiently. In the US, earthworks contractor Beaver Excavating is testing Trimble’s new machine control platform and is achieving high accuracy and consistent excavation and grading in less time.

Using machine control in earthmoving boosts efficiency
December 19, 2017
The use of new machine control tools has made a significant boost in earthmoving efficiency. Automated grade control using GNSS signals has transformed how earthmoving contractors get work done. Through the engineering efforts of its innovators and developers, machine control technology has been improved and refined over the years. A development in the ongoing evolution of machine control technology is Topcon Positioning Systems’ introduction of its 3D-MCMAX integrated 3D dozer system. Most notably, the

LiDAR surveying is making inroads into asset management
December 18, 2017
In the coming age of the autonomous vehicle, fast and accurate LiDAR surveying will be increasingly important, explains Valdis Vanags. The game-changing introduction of autonomous vehicles relies not only on intelligent traffic systems but well maintained roads to help computer-guided systems navigate using road markings. Laser scanning technology, too, is a game changer when it comes to planning and executing many civil engineering projects, including transport network upgrades and smart city initiatives.

Efficient truck loading to optimise operations
December 15, 2017
Accurate technology has been utilised to measure the loads carried by dump trucks on a project in Russia. Specialist supplier LASE commissioned the LaseTVM tool on a road construction site for contractor EuroTransStroy at a construction site in St Petersburg, Russia. The laser-based measurement system is able to determine the volume of bulk materials such as sand and crushed stones with high accuracy. This can be used to prevent differences in loads from one truck to another, so as to ensure consistency.
