In 2003, Virginia launched an expanded commitment to stone matrix asphalt (SMA). By the end of 2004, contracts that encompassed nearly 400,000 tons of SMA had been awarded and most of the material produced and placed. During this 2-year timeframe, more construction districts and contractors were engaged in the design, production, and placement of SMA than at any time in the history of the Virginia Department of Transportation (VDOT). Most were experiencing it for the first time. This report documents many aspects of the 2003/2004 SMA "implementation initiative." It summarizes and presents detailed information on costs and quantities, volumetric properties, compaction, permeability, aggregate quality, and initial functional character (ride and friction) for SMA pavements placed during the 2003 and 2004 seasons. SMA is a complex and expensive HMA material. Carefully documenting (or "baselining") today's experiences and understanding the consequences in terms of lifetime costing are important keys to the continued successful deployment of the best HMA technologies for Virginia. If the cost savings associated with SMA (as identified by the National Asphalt Pavement Association) continue and are applied to only the 14% of VDOT's annual program allotted to SMA in 2005, the fruits of this research can contribute to more than $14 million per year in savings.

The Virginia Department of Transportation (VDOT) maintains 3,343 lane-miles of composite pavements (asphalt over jointed concrete or continuously reinforced concrete pavements). Propagation of cracks from existing pavements into new asphalt concrete overlays (reflective cracking) is a major problem with composite pavements. Treatments that are used to reduce or mitigate reflective cracking include the use of asphalt mixtures with highly modified binders. One way of modifying asphalt mixtures is by using ground tire rubber (GTR), also referred to as rubber modified asphalt. There are three ways of adding GTR to asphalt mixtures: (1) traditional wet process, (2) terminal-blend wet process, and (3) dry process. The traditional wet process blends GTR with asphalt binder or bitumen on-site at the asphalt mixture plant prior to mixing the GTR modified asphalt binder with aggregate. The traditional wet process, along with a gap-graded stone structure, is typically used for incorporating higher GTR concentrations (>15%). VDOT has limited experience with rubber modified asphalt mixtures in general and even less experience with GTR content that exceeds 10%. The purpose of this study was to establish a performance baseline for an asphalt rubber gap-graded mixture (AR-GGM 12.5) using the wet process on I-85 in the Richmond District (I-85 Southbound, Dinwiddie County). Another objective was to compare its performance with VDOT’s stone matrix asphalt (SMA) mixture, which is also a gap-graded mixture. This study found that AR-GGM mixtures can be placed with no special field accommodations (compared with SMA mixtures), and the special provision developed for AR-GGM mixtures is effective. Further, based on laboratory performance testing, both the AR-GGM and SMA control mixtures tested in this demonstration project were crack and rutting resistant, with the AR-GGM mixture exhibiting more flexibility (i.e., lower stiffness). Both sections are performing as expected after 3 years of traffic and exhibiting minor to no distresses, with a Critical Condition Index greater than 90. However, at this early stage of field service, it is too soon to quantify a performance advantage of AR-GGM mixtures in comparison with conventional SMA mixtures. This study recommends continued use of AR-GGM mixtures for suitable projects as a reflective cracking mitigation tool. Further, the study recommends continued performance monitoring of the study sections to evaluate the cost-effectiveness of AR-GGM mixtures in comparison with SMA mixtures.

SMA is a gap-graded mix filled with a rich asphalt-fines mastic developed in Europe. In 1991 five states constructed trial sections to determine if satisfactory mixes could be produced in the United States with current materials and high rates of production. This report discusses Virginia's first section, placed in 1992 near Lynchburg. During construction, better equipment was necessary to control the amount of fines contained in SMA mixes. Lack of control in the mix gradation caused variability on the roadway and on routine mix tests conducted during construction. The mix containing the cellulose fiber, Arbocel, has rotted more at stop-lights than the mix containing the polymer, Vestoplast, or the high-stability control mix. However, all mixes continue to perform well. Laboratory creep tests and gyratory shear tests predicted that the control mix and Vestoplast mix would be more resistant to rutting and consolidation under traffic. This investigation and work in other states have improved the current Virginia specification for SMA. The gradation was coarsened, a stiffer asphalt cement was required, and plant equipment that can adequately handle the aggregates was used. With these changes, future installations will perform better than the current dense graded mixes.

In the years since the development and subsequent success of Stone Matrix Asphalt (SMA), a plethora of articles have emerged, scattered throughout various publications. The time is right for a comprehensive resource that collects, examines, and organizes this information and makes it easily accessible. A compilation and distillation of the latest knowledge available, Stone Matrix Asphalt: Theory and Practice describes SMA, from its origin through implementation, and explores various methods and design approaches. Detailing the requirements and materials for the mix, including asphalt binder, aggregates, and stabilizers, the book covers standard and alternative design methods and their execution, as well as best practices and production processes. It addresses issues such as permanent deformation and fatigue resistance, as well as special applications, such as bridge deck surfacing and airfields. The book uses practical examples to illustrate theory, presents practical tips useful in everyday work, and includes a review of problems that can occur during laydown, and their potential solutions. Drawn from the author’s extensive experience during the introduction of SMA in the early 1990s and discussions with many process engineers, the book provides the practical information needed to customize methods for individual applications of SMA. Blazejowski puts together a picture, drawn from a broad range of literature. The result: a reference that is handy, practical, and easy to use.
