Available in PDF, EPUB and Kindle. Book excerpt: This investigation is part of CRREUs on-going characterization of pavement performance in seasonal frost areas. As part of the research, CRREL conducted several field studies for the Federal Aviation Administration (FM) on the response of airport pavements during thaw-weakening periods at three civil airports in Wisconsin, where the design freezing index in the area was around 900 to 1100oC-days and frost penetration ranged between 1250 to 2000 mm. This study focused on the performance of Portland Cement Concrete (PCC) pavements during the spring thaw-weakening period. The sites were instrumented with subsurface thermocouples and Falling Weight Deflectometer (FWD) tests were conducted during the spring thaw period at the center of the slab and across the joints. An analysis of the FWD data and backcalculation of the layer moduli using ILLIBACK and WESDEF was conducted. Unique relationships between the FWD deflections and the subgrade modulus and coefficient of subgrade reaction were obtained. Additional relationships were developed using the FWD deflections, PCC thickness and the horizontal tensile stress at the bottom of the PCC layer. A relationship between load transfer across joints and FWD deflections was also developed. On the basis of the relationships obtained in this study, a methodology for evaluating PCC pavements during spring thaw was developed. However, this methodology needs to be verified for other subgrade types and areas with other design freezing indices.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to develop a method to predict the timing of weight limits on secondary highways in Wisconsin. Two types of weight limits are of interest: overloads when the pavement is frozen and weight restrictions during thawing and post-thawing recovery period. To meet this objective, three sections of secondary highways with flexible pavements were instrumented and monitored to determine how freezing, thawing, and post-thaw recovery affect pavement stiffness. Data collected from these sites were used to develop a computer model (UWFrost) that can be used to predict seasonal changes in the support capacity of pavements.

Download or read book Phenolic Based Foams written by Sandhya P.K and published by Springer Nature. This book was released on 2022-01-13 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the latest developments in phenolic foams and their applications. Compared with polystyrene and polyurethane foams, phenolic foams are known as third-generation polymeric foams. Phenolic foams exhibit excellent fire-retardant properties, including low flammability, low peak heat release rate, no dripping during combustion, and low toxicity. This book discusses various aspects of phenolic foams including properties, synthesis, fabrication methodologies, and applications. The contents also cover the methods for toughening of phenolic foams to make them more widely applicable. This book is of interest to both academics and industry alike. It is also a useful reference for fire safety regulators and policy-makers looking for new materials and methods for sustainable fire protection.
