Abstract

The two principal modes of structural distress that occur in highway and road pavements as a result of traffic loading are deformation or rutting and cracking. Creep or deformation is caused by the deformation within the depth of the pavement. The accumulation of the permanent deformation within the road structure will cause rutting. Excessive rutting will normally lead to cracking, while the penetration of water and fines can result in the rapid damage of the pavement structure. Cracking in bituminous mixture, on the other hand is a fatigue phenomenon that depends upon the tensile strains induced in the material. This study involves some laboratory work on the deformation and fatigue characteristics of Hot-Rolled Asphalt (HRA) mixtures modified with polymer additives and fibres. The additives used were SBS and EVA whilst synthetic fibres used were polypropylene and polyester. (Author/publisher) For the covering entry of this conference, please see ITRD abstract no. E208431.
