construction sites, but technology and legislation are moving in that direction.
At the moment drones can fly within only a 500m radius of the ‘pilot’ standing on the ground, making the flight area a 1km diameter. This is the key limiting issue for any sector, especially road construction, says Jonathan Gill, a robotics engineer and a qualified drone
pilot for the past seven years.
The logic is that a drone remains withi
Special reinforcements can extend the life of an old or new road, and also offer environmental benefits. Patrick Smith reports. Asphalt reinforcement can extend the service life of a resurfaced road by a factor of 3-4, says Huesker, developers of the HaTelit range of asphalt reinforcement. Aimed at preventing the propagation of reflective cracking from an old asphalt layer through a new surface course, Huesker claims the formation of reflective cracking is considerably delayed or even completely prevented u
