Denmark: New type of asphalt concrete tested

Roskilde University, the Department of Civil Engineering at the Technical University of Denmark (DTU Byg), Swedish construction company NCC and the Danish Road Directorate (Vejdirektoratet) are involved in the COOEE research project, which aims at developing a type of asphalt concrete that results in lower friction compared to traditional paving. Tests have shown that friction can be decreased by up to 10% with the new material, and this could in turn reduce the consumption of fuel by up to 3%. There

Roskilde University, the Department of Civil Engineering at the Technical University of Denmark (DTU Byg), Swedish construction company 1084 NCC and the Danish Road Directorate (Vejdirektoratet) are involved in the COOEE research project, which aims at developing a type of asphalt concrete that results in lower friction compared to traditional paving.

Tests have shown that friction can be decreased by up to 10% with the new material, and this could in turn reduce the consumption of fuel by up to 3%.

There is a challenge in reducing friction while at the same time retaining favourable qualities related to functionality and safety. The material will next be tested on a major road with high traffic intensity.

Denmark’s DTU invents new concrete production method

The Technical University of Denmark (DTU) has invented a new method to separate ashes from burnt wastewater sludge and use it for concrete production. DTU has patented a method for electrodialytic separation of secondary raw materials. It is now hoping to enter into cooperation with the construction sector to use the wastewater sludge ashes, that have been purified from phosphorus and heavy metals, as a replacement for cement in concrete production. This could make it possible to market such concrete as a g

Volvo CE’s work to deliver the Quarries of Tomorrow

Volvo Construction Equipment’s electric site research project marks a new way of working, combining intelligent machines, automation, electromobility and total site solutions to help shape the quarries of the future. Volvo Construction Equipment’s (Volvo CE) electric site research project aims to transform the quarrying and aggregates sector by reducing carbon emissions by up to 95% and total cost of ownership by up to 25%. The company first presented its electric site solution around a year ago when it
