Heavy static loading that is present on airfields aprons, on storage areas at industry facilities and on road sections such as bus lanes and bus terminals needs pavement materials that are rutting resistant and have a high stiffness modulus, even at low loading frequencies. The traditional selection of materials for this type of loading has been rigid pavements such as cement concrete. However the need for more flexible materials that can obtain deformations without cracking and without joints both leading to lower maintenance cost has been asked for. This has resulted in the development of a semi-flexible material for heavy loading areas. The semi-flexible pavement material is defined as a composite material consisting of an open graded asphalt material where micro silica mortar is penetrated into the air voids.
