Asphalt is a sticky, black liquid used for road surfacing, while macadam is a type of road construction using layers of crushed stone bound with tar.
Asphalt impregnation of steam cured high strength mortar and concrete is studied. The test specimens were dried at 105°C to constant weight and heated to temperatures between 50 and 350°C before impregnation. The impregnation was carried out at atmospheric pressure by dipping the test specimens ...
Polyacrylonitrile fibers, also known as acrylic fibers, can be used not only in mortar and cement concrete, but also in asphalt concrete because of their high tensile strength, good oil absorption and hydrophilicity, high temperature resistance, non-swelling, strong adsorption and chemical stability. ...
