Book excerpt: This synthesis will be of interest to pavement designers, construction engineers, and others interested in economical methods for reconstructing or rehabilitating bituminous pavements. Information is provided on the processes and procedures used by a number of states to recycle asphalt pavements in place without application of heat. Since 1975 a growing number of state highway agencies have reconstructed or rehabilitated asphalt pavements by recycling the old pavement in place. This report of the Transportation Research Board describes the processes used for cold in-place recycling, including construction procedures, mix designs, mixture properties, performance, and specifications.

This book was released on 2020 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: To maximize the life and quality of a pavement, proper maintenance and rehabilitation are essential. Strategies for pavement rehabilitation with many sustainable benefits are pavement recycling. This dissertation focuses on two types of in-situ pavement recycling: Cold in-place recycling (CIR) stabilized with asphalt emulsion and full depth reclamation (FDR) stabilized with asphalt emulsion or foamed asphalt. One white paper (Chapter 2), two accepted peer reviewed journal articles (Chapters 3 and 4), and one submitted peer reviewed journal article (Chapter 5) are presented in this document to create better understanding of the unique material characterization of asphalt emulsion cold recycled materials, along with factors which influence characterization, pertaining to the measurement of workability, compactability, and cohesion gain. In Chapter 2, a detailed review of the progression of mix design procedures for unbound granular materials (UGM), fully bound hot mix asphalt (HMA), and semi-bound asphalt emulsion CIR is presented to establish the current state of mix design for each material type and identify ways the design of asphalt emulsion CIR could become more engineered rather than empirical. Recommendations included development of additional guidance on use of active and inert fillers, a methodology to account for workability and compactability during mix design, curing procedures which more closely mimic conditions in the field to improve cohesion gain, and a procedure for determination of optimum water content. In Chapter 3, a study was conducted to evaluate different laboratory compaction methods for compaction of asphalt emulsion and foamed asphalt FDR. Both the Proctor hammer, typically used for UGM, and the Superpave Gyratory Compactor (SGC), typically used for HMA, were compared by evaluating densities, tensile strengths, and compaction metrics of FDR samples produced using each method. The modified Proctor hammer produced samples with the highest dry unit weights; however, samples produced using the SGC had higher tensile strengths, indicating compaction method affects material properties. Chapter 4 evaluates different test methods and equipment commonly available in asphalt laboratories for ability to quantify workability, compactability, and cohesion gain of asphalt emulsion CIR by measuring differences in performance due to changes in laboratory curing conditions. Cure temperature was found to have a more significant influence on test results than cure time. SGC metrics were recommended for quantifying workability and compactability. The direct shear test showed promise for quantifying cohesion gain. Finally, Chapter 5 measured effects of various sample fabrication factors on measurement of workability, compactability, and cohesion gain in order to address open questions associated with asphalt emulsion CIR laboratory procedures. Curing temperature most significantly influenced workability and compactability; while cohesion gain was more significantly influenced by mixing temperature and specimen test temperature. The direct shear test again showed promise for measuring cohesion gain of asphalt emulsion CIR. Therefore, a draft specification for this test method was prepared and is included as an appendix of this dissertation. A singular test method for quantifying workability and compactability for asphalt emulsion CIR has not yet been identified due to multiple mechanisms at play during mixing and compaction stages for this material.

This book was released on 2019-08-29 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume highlights the latest advances, innovations, and applications in the field of asphalt pavement technology, as presented by leading international researchers and engineers at the 5th International Symposium on Asphalt Pavements & Environment (ISAP 2019 APE Symposium), held in Padua, Italy on September 11-13, 2019. It covers a diverse range of topics concerning materials and technologies for asphalt pavements, designed for sustainability and environmental compatibility: sustainable pavement materials, marginal materials for asphalt pavements, pavement structures, testing methods and performance, maintenance and management methods, urban heat island mitigation, energy harvesting, and Life Cycle Assessment. The contributions, which were selected by means of a rigorous international peer-review process, present a wealth of exciting ideas that will open novel research directions and foster multidisciplinary collaboration among different specialists.

Book excerpt: Reuse of reclaimed asphalt pavement (RAP) in the full-depth recycling (FDR) process is a cost-effective and environmentally responsible method of asphalt pavement reconstruction. Although FDR has been used for several years in some locations, the effect of RAP on the mechanical properties of recycled base materials has not been well documented. The purpose of this research was to investigate the influence of RAP on the mechanical properties of recycled base materials typical of northern Utah.

This book was released on 2013 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recycled materials and industrial byproducts are being used in transportation applications with increasing frequency. There is a growing body of experience showing that these materials work well in highway applications. This study gathers the experiences of transportation agencies in determining the relevant properties of recycled materials and industrial byproducts and the beneficial use for highway applications. Information for this study was acquired through a literature review, and surveys and interviews with state department of transportation staff. The report will serve as a guide to states revising the provisions of their materials specifications to incorporate the use of recycled materials and industrial byproducts, and should, thereby, assist producers and users in leveling the playing field for a wide range of dissimilar materials.
