Book excerpt: Seal coat is a layer of asphalt binder with a layer of aggregate applied over a pavement. The purpose of a seal coat is to seal the pavement from air and water intrusion while providing the safety benefits of maintaining sufficient friction over the seal coat's design life. With an investment of over $300,000,000 annually, it is imperative to construct a high-quality project. To achieve quality construction, it is important to establish and adjust the application rates for the binder and aggregate based on the materials being used, traffic and existing roadway conditions. This project produced guidelines for improvements to rate design procedures that will help engineers and inspectors make better decisions resulting in successful projects.

Available in PDF, EPUB and Kindle. Book excerpt: The size of the highway network has grown beyond the manageable capabilities of transportation agencies and stakeholders who are concerned with maintaining their assets using limited funding abilities. For that reason, pavement preservation programs have become very popular because they offer cost-effective spending schemes that maximize the service life of roads. Seal coats are one of the most popular pavement preventative treatments used around the world due to their high durability and low cost compared to other surface treatments. Their performance depends on the adequate computation of the aggregate and binder application rates. Misestimating these rates leads to raveling, bleeding, or other distresses. Accordingly, numerous design methods have been developed and are being implemented worldwide. This research assesses the different design philosophies and considers the assumptions adopted by each. It is challenging to design a seal coat when several design methods recommend different and inconsistent application rates. For the first time, the three-dimensional laser is incorporated in the design of seal coats in order to provide a fast, objective, and reliable approach. A predictive model is developed to determine the adequate aggregate application rate based on the size of the aggregates, i.e. the average least dimension, and their density. This study also assesses the contemporary texture characterization techniques and analyzes the variance of the sand patch test. The findings indicate that the sand patch test is not a reliable estimator of the volume of voids in the surface texture, which negatively affects the calculation of the binder application rate. The study recommends an algorithm that accurately measures the volume of voids in the existing surface texture using 3D surface scans. The outcome enhances the estimation of the binder application rate, and the findings can be applied to the existing design methods to improve the performance of the seal coat. Finally, highway agencies could incorporate the 3D laser within the binder sprayer to measure the surface texture during construction and automatically adjust the rate

Book excerpt: Extensive programmed laboratory tests involving some 400 asphalt emulsion slurry seals (AESS) were conducted. Thirteen aggregates including nine Iowa sources, a quartzite, a synthetic aggregate (Haydite), a limestone stone from Nebraska, and a Chat aggregate from Kansas were tested in combination with four emulsions and two mineral fillers, resulting in a total of 40 material combinations. A number of meetings were held with the Iowa DOT engineers and 12 state highway departments that have had successful slurry seal experiences and records, and several slurry seal contractors and material and equipment suppliers were contacted. Asphalt emulsion slurry seal development, uses, characteristics, tests, and design methods were thoroughly reviewed in conjunction with Iowa's experiences through these meetings and discussions and through a literature search (covering some 140 articles and 12 state highway department specifications). It was found that, while asphalt emulsion slurry seals (when properly designed and constructed) can economically improve the quality and extend the life of existing pavement surface, experiences with them had been mixed due to the many material, slurry, and construction variables that affect their design, construction, and performance. The report discusses those variables identified during the course of the project and makes recommendations concerning design procedures, design criteria, specifications and the means of evaluating them.
