  2. 1. Screening of Crushed Rock Material

    Author : Monica Soldinger Stafhammar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The quality requirements for sand, gravel and crushed rock material used on roads and railroads have been raised in recent years, hence suppliers must meet more rigorous demands. It is now necessary to improve the understanding of all parts of the production line. READ MORE

  4. 2. Free mica in crushed rock aggregates

    Author : Eva Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoteknik; Soil Mechanics;

    Abstract : Free mica particles in crushed rock aggregates for constructional purposes affect the quality of the end product. It is also known that mica-bearing rocks may cause damages of the road constructions, especially in regions with a temperate climate. The negative influence arises in both bounded and unbounded layers. READ MORE
