Undersökning av hur penetrationstalet i bitumen påverkar styvheten av cementstabiliserad asfalt i laboratoriepackade prover
A semi-flexible pavement is a composite material consisting of an open-graded asphalt skeleton with an air void content between 25 - 35% that is filled with a cement sludge. Limited research has been done regarding factors which can affect the mechanical properties of this material. Therefore, this study explores the affect the penetration value of a bitumen has on the stiffness of a semi-flexible
