A STUDY OF RECYCLING FEASIBILITY. FINAL REPORT
This report describes a feasibility study of recycling asphalt pavements using two major analytical techniques: High Performance Gel Permeation Chromatography (HP-GPC) and Dynamic Mechanical Analysis (DMA). HP-GPC probes the chemistry of the asphalt cement. DMA measures certain physical characteristics of the asphalt cement and of the mix. Four projects that had been recycled, three by hot methods, the other by a cold, in-place process (CIPR), were studied. Specifically, the HP-GPC characteristics of the asphalts before and after recycling and the resilient moduli of some recycled mixtures were obtained. In addition, three sources of recovered asphalt pavement were subjected to modeling of hot and cold recycling strategies and tested by DMA on mixes as well as by HP-GPC. Finally, an additional five pavements that are candidates for recycling were sampled and the asphalt cements extracted for HP-GPC and DMA testing using both hot and cold recycling simulations. This report details the study procedures and discusses the data and their interpretations. Included in this report are data on the HP-GPC characteristics of the asphalt cements available in the state of Montana in 1993. Also, testing of asphalt cements from an experimental project and a distressed pavement is addressed briefly.
