This book was released on 2016 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high-performance mortar (HPM) containing a large amount of industrial by-products such as fly ash, silica fume, and limestone fines was developed for rapid repair of concrete pavements. The HPM development included three major steps. 1. Development of the mortar mixture proportion based on the optimal hydration of binder and particle packing of the mortar system. In this step of the study, all mortar materials were systematically proportioned, and the obtained mixtures were tested for flowability, rate of hydration, set time, and strength development. The optimal mixture proportion was then selected as the HPM, as it displayed good self-consolidating ability and achieved 1-day compressive strengths greater than 6,000 psi. 2. Investigation of the mechanical properties of the new HPM, including compressive and flexural strength, elastic modulus, and slant shear and pull-off strengths of patch-substrate bonds tested at 1, 3, 7, and 28 days. In this step, the properties of the HPM were evaluated in comparison with those of a commercial repair material: the rapid-set concrete (RSC). Two types of substrates representing old concrete were used for patching repair. One was made of a typical pavement mixture (C-3WR-C20), and the other was a high-strength pavement concrete mixture (O-4WR). 3. Investigation of the durability properties of the newly developed HPM compared to those of the RSC. Durability properties included cyclic freeze-thaw (F-T) resistance, permeability, and shrinkage behavior. The results indicated that the newly developed HPM possesses excellent self-consolidating ability: highly flowable and non-segregating. Although there was delayed setting, the compressive strength of the HPM exceeded 6,000 psi at 1 day, approximately 25 percent higher than that of the RSC. At 28 days, the HPM reached 10,000 psi, while the RSC was about 7,000 psi. The HPM also displayed extremely low chloride permeability (18 coulombs) compared to the RSC (2,550 coulombs) and excellent F-T durability without the requirement for air entrainment. The F-T durability factor of HPM was kept around 100% throughout the standard F-T test, while the F-T durability factor of RSC reduced to 80% at the end of the F-T test. However, the HPM exhibited noticeably higher autogenous shrinkage and slightly lower free drying shrinkage than the C-3WR-C20 mixture, while the RSC had a little/no shrinkage during the 56-day test period. Addition of a small amount of micro-steel fibers (70 pcy) slightly reduced the shrinkage of the HPM. Further studies on fatigue and shrinkage cracking behavior of the HPM are recommended.

Available in PDF, EPUB and Kindle. Book excerpt: In support of a broader MnDOT effort to evaluate current practices, materials, and policies for pavement patching and repair for both asphalt and concrete pavements, the University of Minnesota Duluth Natural Resources Research Institute (NRRI) conducted additional evaluation, refinement, field testing, and performance monitoring of two taconite-related approaches to pavement repair that rely on mixes/techniques that contain (or are enhanced by) taconite mining byproducts and co-products. The first taconite-related approach to pavement repair uses a rigid pavement/pothole repair compound formulation developed and patented by NRRI that is fast-setting, taconite-based, and contains no petroleum or Portland cement. Depending on the formulation, the repair compound can be water-activated or activated by a chemical solution. A water-activated formulation referred to as Rapid Patch was the focus of the investigation. The second taconiterelated approach to pavement repair employs a high-power (50kW), vehicle-based (truck-mounted) microwave system for in-place pothole/pavement repair/recycling in which magnetite and/or magnetite-containing aggregate (taconite rock) can enhance microwave absorption and therefore the system’s performance. The two repair alternatives evaluated during this project merit further development and consideration, as the field performance of both suggests they have long-term potential for more widespread use. Based on feedback from maintenance personnel who used and/or observed both repair alternatives during the project, both alternatives would benefit from operational modifications that would reduce the deployment time required to complete a repair and increase the number of repairs that can be accomplished during a single shift. Doing so would likely lead to greater acceptance and more widespread use.

Available in PDF, EPUB and Kindle. Book excerpt: The Strategic Highway Research Program's project H-106, the partial-depth spall-repair experiment, is the most extensive effort to date to evaluate the performance of various rapid-setting materials and procedures used in the repair of partial-depth spalls in Portland cement concrete pavements. Four test installations consisting of a total of 1,607 patches, were constructed in 4 climatic zones, and the experiment investigated the performance of several cementitious, polymeric, and bituminous patching materials, and procedures used in repairing jointed concrete pavements. The techniques included the following: saw and patch, chip and patch, mill and patch, waterblast and patch, and minimal praparation clean and patch under adverse conditions. The patch performance has been good: only 2.3% of the patches have failed.

This book was released on 2014 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Pavement patching is a common maintenance activity in the state of Ohio, due to numerous freeze-thaw cycles. The Ohio Department of Transportation (ODOT) has a need for durable, more permanent high performing pavement and bridge deck materials that allow for a faster repair and for user safety. New or proprietary products were chosen, installed, and monitored in order to specify for use in future ODOT construction, based on the field performance of the products. The objective of this study was to document the investigation, installation, and field testing of the previously chosen high performance patching materials. The investigation determined the proper field testing criteria used throughout this project. The installation of the patches was performed in both winter and summer weather conditions. Observations regarding the different products installed, and the installation process, were documented throughout the installations in order to determine which products are easier to install, and in order to document the potential problems that could arise throughout a future patching project. Field testing and visual inspections were performed throughout the project as well, in order to determine the overall performance of the products being tested. The proper installation and testing of these new products will assist in determining the overall performance of these patching products.

Available in PDF, EPUB and Kindle. Book excerpt: This project investigated the properties and performance of the products used for spall repair of concrete pavement. A survey of Texas Department of Transportation (TxDOT) maintenance engineers produced a roster of 10 repair materials currently in use in the state. After identifying the key characteristics of a successful repair material, a laboratory testing program was developed to evaluate the properties of the repair materials. These materials were tested for strength, compatibility, and bond to quantify their characteristics relative to those products known to work well.
