Abstract:

Asphalt cement, rubber extender oil, and a mixture of ground reclaim and crumb rubber, blended together at an elevated temperature in specific proportions and sequences, form a tough, durable, and adhesive membrane when hot-spray-applied to a surface and allowed to cool to ambient temperatures. This cast-in-place asphalt-rubber membrane has been found to be suitable for use in the construction of surface treatments for existing pavements (chip seals), stress-absorbing membrane interlayers (SAMIs) in the placing of asphalt concrete overlays, and waterproofing membranes for bridge decks and hydraulic linings (ponds, canals, and reservoirs). When hot-poured into pavement joints and cracks and allowed to cool, it also serves as an effective joint and crack filler. The concepts and proportions of the formulation and preparation of this material are presented together with information and data on its properties and applications. A discussion is presented of the results of two analytic studies on the applicability of asphalt-rubber membranes (a) in minimizing reflection cracking when used as a SAMI and (b) in producing a "multilayered aggregate structure" when used as a single-pass chip seal. A summary of the field performance observed to date on a number of installations of the asphalt-rubber material in its various applications is also included, together with observations on the efficacy of the material as a membrane and as a filler.
