Estonia recycling shale ash for road materials

Estonia is developing plans to use recycled shale ash in road construction. Energy firm Eesti Energia is working on developing technical standards for the use of shale oil ash in road building. The firm expects to take 12 months to develop the necessary standards, with the use of the material due to commence in 2017.

The firm expects to take 12 months to develop the necessary standards, with the use of the material due to commence in 2017. Eesti Energia claims that shale ash offers excellent binding properties, which suits its use in road building. A number of test projects have been carried out for Eesti Energia using the material and these trials reveal shale oil ash to offer a suitable performance.

    May 12, 2016
    An ambitious objective has led to significant steps in the reuse of PA (porous asphalt). While the market incidentally produces PA with a maximum of 30% of recovered raw materials, BAM has introduced its own innovations, enabling more than 90% of raw materials to be reused. And this year, subsidies from the European Commission will enable the LE2AP demonstration project to be constructed: one kilometre of sustainable PA. Large-scale production is also being developed.

    Automated road repairs using 3D printing could save money and reduce disruption, reports Kristina Smith It’s the middle of the night and in the street below a team is busy carrying out repairs to the road surface. But there isn’t a human in sight. A road-repair drone has landed at the site of a crack and a 3D asphalt printer is now busy filling in that crack. A group of traffic cone drones have positioned themselves around the repair location to protect the repair drone and divert traffic around it.

  • Asphalt and bitumen - testing for performance
    February 29, 2012
    The stresses placed on modern asphalt and bitumen means that specialist equipment is essential to make sure performance specifications are met. As road traffic increases at a rapid pace and road safety becomes a priority issue, asphalt is put under increasingly higher stresses. For example, road surfaces are subject to compression, flexural tensions and tangential stresses: internal friction, depending on the aggregates, and the cohesion, guaranteed by bitumen's composition, are the two main properties whic
