RECYCLING OF SUBSTANDARD OR DETERIORATED ASPHALT PAVEMENTS -- A GUIDELINE FOR DESIGN PROCEDURES

This paper presents the results of an extensive laboratory study designed to define the chemical and physical deficiencies of deteriorated asphalt pavements and to provide the design engineer with practical guidelines for correcting the deficiencies. After reviewing the pertinent literature and past experience with asphalt reclaiming, and after conducting preliminary orientation tests, the authors formulated a design concept for the recycling of deteriorated asphalt pavements utilizing the addition of a single reclaiming agent. A laboratory investigation was carried out to test the formulated concept in consecutive work phases, each designed to verify and expand the preceding phase. Six asphalts of different durability characteristics and representative of all currently available asphalts, one asphalt extracted from an old pavement, six artificially aged asphalts and twelve different reclaiming agents were tested.
