A desire to maintain a safe, efficient, and cost-effective roadway system has led to a significant increase in the demand to rehabilitate the existing pavements. Asphalt pavement recycling has grown dramatically over the last few years as the preferred way to rehabilitate existing asphalt pavements. A number of different techniques has been employed in the rehabilitation of existing asphalt pavements. One of these is Cold Inplace Recycling with foamed asphalt (CIR-foam). However, the current CIR-foam practice utilizes a generic recipe specification without a mix design, where a contractor is given latitude to adjust the proportions of the foamed asphalt content to achieve a specified level of density. Therefore, this study was conducted to develop a consistent laboratory mix design in consideration of its predicted field performance. First, the CIR-foam mix design parameters were identified and a new laboratory mix design procedure of CIR-foam mixture was developed. The developed mix design procedure was then validated using different sources of RAP materials. The simple performance tests, which include a dynamic modulus test, a dynamic creep test and a raveling test, were used to evaluate the consistency of a new CIR-foam mix design process to ensure reliable mixture performance over a wide range of traffic and climatic conditions.

Asphalt pavement recycling has grown dramatically over the last few years as a viable technology to rehabilitate existing asphalt pavements. Iowa's current Cold In-place Recycling (CIR) practice utilizes a generic recipe specification to define the characteristic of the CIR mixture. As CIR continues to evolve, the desire to place CIR mixture with specific engineering properties requires the use of a mix design process. A new mix design procedure was developed for Cold In-place Recycling using foamed asphalt (CIR-foam) in consideration of its predicted field performance. The new laboratory mix design process was validated against various Reclaimed Asphalt Pavement (RAP) materials to determine its consistency over a wide range of RAP materials available throughout Iowa. The performance tests, which include dynamic modulus test, dynamic creep test and raveling test, were conducted to evaluate the consistency of a new CIR-foam mix design process to ensure reliable mixture performance over a wide range of traffic and climate conditions. The "lab designed" CIR will allow the pavement designer to take the properties of the CIR into account when determining the overlay thickness.

Cold in-place asphalt recycling has been shown to be a technically sound, cost-effective, environmentally friendly method of strengthening and maintaining a wide range of deteriorating asphalt pavements. The overall process combines testing and mix design procedures, milling, processing and mixing units with microprocessor control of emulsion addition, compaction, placement of a wearing surface and quality assurance testing. It has been shown, in laboratory work and a number of Ontario projects the past four years, that modification of the cold in-place process to incorporate new aggregate results in an improved recycled binder course with closer voids and stability control, addressing observed conventional cold in-place asphalt recycling problems such as: high residual asphalt cement content (flushing); tine mix (high percent passing 4.75 mm and 75 pm); rutting (low initial stability with emulsion system); and adequacy of in-place material thickness. Structural equivalency factors for cold in-place recycled asphalt compared to conventional binder course hot-mix asphalt have been developed. Resilient properties of laboratory and field samples have been determined with the Nottingham Asphalt Tester (NAT) and used in standard mechanistic design programs such as BISAR. Future applications of modified cold in-place asphalt recycling to improve flexible pavements will undoubtedly include airports, which will require consideration of special features such as operational constraints.

Recycling of asphalt pavements has become a widely accepted practice, particularly in North America and Europe. Several technologies have emerged to fill the various rehabilitation needs, depending on local conditions, type of pavement, and the future use of the roadway. Both hot and cold recycling in a central plant are routinely practiced. Cold in-place recycling (CIR) and full depth reconstruction is used by many highway agencies to restore surfaces and stabilize existing roadways for future overlays. Hot in-place recycling (HIR) has been used sparingly during the past 50 years, and only since the late 1980s have acceptable processes and equipment been developed. Much of the technolgical development, experience, and HIR technology has occurred in Canada, where highway agencies have embraced the concept and equipment manufacturers have provided innovations. The paper briefly describes the development and special characteristics of the various HIR processes. It describes the development of a new heating system that combines recirculating hot air with low-level indirect infrared components. In addition, a stirring mechanism has been incorporated in the heating system to ensure more uniform heating of the loose asphalt mixture and efficient removal of any moisture. The recirculated hot air is reheated, and then incinerated, thereby providing a significant improvement in air quality compared to previous generations of HIR equipment. The data from early trials in British Columbia, Canada show that the productivity is increased and the quality of recycled pavement is improved. In recent years air quality has been a factor in the acceptance of HIR in North America. Monitoring of the quality of air released at the new heating system shows the particulate matter and other solids to be the lowest among HIR systems tested. Additional projects are currently underway in Europe using the latest version of this equipment that was developed by Martec Recycling Corporation and these may provide additional data for the presentation.

This study evaluates one of the recycling techniques used to rehabilitate pavement, called Cold In-Place Recycling (CIR). CIR is one of the fastest growing road rehabilitation techniques because it is quick and cost-effective. The document reports on the current practice of CIR with emulsion, presents a literature review of research on foamed asphalt, discusses the foaming experiment, presents a field data collection and compaction study, and describes the determination of mix design parameters for CIR with foamed asphalt.
