Available in PDF, EPUB and Kindle. Book excerpt: Some engineered wood fiber surfaces are uneven, tend to shift, and have low density. The goal of our research was to develop a playground surface material that cushions impact and is accessible to people with disabilities. In the initial screening phase, we evaluated a variety of in situ surface treatments and mixtures of wood particles combined with various binders. Engineered wood fiber (EWF) was prepared from three species, red maple, ponderosa pine, and one-seed juniper, which have a wide range of densities and bonding properties. In the scale-up phase, we evaluated commercially available EWF and several promising binding systems from the screening phase trials. Seventeen test configurations were formed in plywood boxes, using different levels of EWF compaction, fiber moisture content, surface layer thickness, and types of binders. Binder systems that show promise for surface stabilization and satisfactory impact behavior are polyurethane, latex, and silicone. These binders were chosen on the basis of processing ease, flexibility (elongation to failure), cost, and safety in application and use. In this report, we identify the strengths and weaknesses of the surface treatments, review the viability of the systems and the testing concepts we have developed, and identify further research needs.

This book was released on 2003 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some engineered wood fiber (EWF) surfaces on playgrounds are soft and uneven, which creates difficulties for those who use mobility aids, such as wheelchairs and walkers. The outdoor field testing reported in this study is part of an effort to stabilize EWF to improve accessibility. The concept is to mix a binder with the upper surface of EWF to create a stiff (firm) and scuff-resistant (stable) composite overlayer. Latex, silicone, and polyurethane binders were evaluated on small plots during a 6-month outdoor trial in Wisconsin. Tests were performed at regular intervals to‍?provide a quantitative measure of accessibility. After 6 months of exposure, all the surfaces passed the existing specifications for impact attenuation of playground surfaces. Exposure changed impact performance of all systems except the unsurfaced (without an additive) EWF. The latex and‍?polyurethane stabilizers consistently met accessibility requirements. One polyurethane formulation produced a hard brittle shell that became even harder with exposure and age, which might increase the injury rate for falls on that surface. The silicone system failed to maintain integrity adequately‍?during the rain/dry cycles of the test. Moisture measurements indicate that the bonded surfaces retard drying of the underlying EWF, which may have long-term implications for the rate of decay for these systems.

Book excerpt: Pavements are the most ubiquitous of all man-made structures, and they have an enormous impact on environmental quality. They are responsible for hydrocarbon pollutants, excess runoff, groundwater decline and the resulting local water shortages, temperature increases in the urban "heat island," and for the ability of trees to extend their roots in

Available in PDF, EPUB and Kindle. Book excerpt: A guide to real-world applications of The 2010 Americans with Disabilities Act Standards for Accessible Design Applying the ADA helps architects and developers understand better how the rules for eliminating barriers in the built environment apply to everyday life and how to best implement them in the design and construction of a broad variety of buildings and facilities. By showing how The 2010 Americans with Disabilities Act Standards for Accessible Design have been applied in various contexts and building types, this extensively illustrated guide helps readers quickly understand the requirements of the standards and how to apply them to both new construction and renovation. Written by an architect who consults regularly on accessibility issues for design professionals, building owners, and facility managers, this user-friendly guide features 100 photos and 150 drawings that take the guesswork out of applying the standards to real-world projects. Building types covered include: Healthcare and senior living facilities and hospitals College and university facilities Elementary and high schools Hotels and other transient lodging facilities Amusement parks and play areas Historic preservation and remodels Retail and office spaces Applying the ADA is an indispensable resource for architects, interior designers, owners, developers, and facility managers. It is also important reading for students of architecture and interior design.
