ABSTRACT

Cold recycled asphalt materials are pavement materials composed of reclaimed pavement granulates and natural aggregates, bituminous and/or mineral binder which are mixed, paved and compacted at ambient temperatures. Internationally applied mix design approaches are commonly based on strength tests conducted on laboratory-mixed and laboratory-compacted specimens. In most specification documents, threshold values are defined for the void content and/or mechanical properties as indirect tensile strength or compressive strength. One important step within the mix design procedure is the preparation of specimen from the cold mixtures. This contribution discusses the bulk characteristics as well as the mechanical properties obtained on specimens after vibratory and static compaction procedures.
