Book excerpt: This report documents enhancement incorporated in the (HIgh PERformance PAVing) HIPERPAV(trademark) II software. Enhancements made within this project include the addition of two major modules: a module to predict the performance of Jointed Plain Concrete Pavement (JPCP) as affected by early-age factors and a module to predict the early-age behavior (first 72 hours) and early life (up to 1 year) of Continuously Reinforced Concrete Pavement (CRCP). Two additional Federal Highway Administration (FHWA) studies were also incorporated: one that predicts dowel bearing stresses as a function of environmental loading during the early age and a module for optimization of concrete paving mixes as a function of 3-day strength, 28-day strength, and cost. Additional functionality to the software also was incorporated by reviewing and prioritizing the feedback provided by users of the first generation of the software, HIPERPAV 1.

Download or read book Developing a Simple and Rapid Test for Monitoring the Heat Evolution of Concrete Mixtures for Both Laboratory and Field Applications Phase III written by and published by . This book was released on 2008 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research project is to identify, develop, and evaluate a simple, economical, and reliable calorimetry device and test method for monitoring heat evolution of pavement concrete. The project contains three phases: phase I - identifying user needs for calorimeter tests, phase II - identifying potential calorimeter devices and developing test procedures, and phase III - verifying the test procedures and the potential applications of calorimetry in field. In this report, the work done in phases I and II is briefly summarized and the study of phase III is presented. The phase III study includes three parts: (1) field calorimetry tests, (2) lab tests for the field materials, and (3) implementation of calorimetry into pavement performance prediction. The field tests were conducted at three selected sites: US 71 (Atlantic, Iowa), Highway 95 (Alma Center, Wisconsin), and US 63 bypass (Ottumwa, Iowa). A simple isothermal calorimetry and two semi-adiabatic calorimetry (AdiaCal and IQ drum) tests were conducted at these sites. The general concrete, such as slump, air content, unit weight, placement temperature, ASTM C403 set time, and pavement properties, such as subbase temperature and sawing time were also measured. In the lab tests of the field materials, nine robust mixes for each field site, with different variations in water reducer and/or fly ash dosages were developed. AdiaCal and isothermal calorimeter tests were performed for each of the robust mixes. IQ drum and ASTM C403 set time tests were conducted for selected mixes. To implement the calorimetry test results into concrete performance prediction, the HIgh PERformance PAVing (HIPERPAV) computer program was modified, the calculated hydration curve parameters from selected calorimetry tests were used as inputs for the modified HIPERPAV program, and the temperature developments of in-situ pavements were then predicted. The phase III test results confirmed the major findings drawn in the phase II study. The results indicate that both the AdiaCal and semi-adiabactic calorimetry tests can provide valuable information on concrete performance. AdiaCal calorimetry is particularly good for field concrete set time prediction, and it is sensitive to the sample temperature. Isothermal calorimetry can provide users more detailed information on cement hydration and provide more consistent test results. The thermal set times obtained from both the AdiaCal and isothermal calorimetry tests are closely related to those measured from the ASTM C403 tests. Using the calorimetry test curve as inputs for the HIPERPAV computer program, in-situ concrete pavement temperatures can be predicted adequately.

Download or read book Concrete Pavement Design Construction and Performance written by Norbert Delatte and published by CRC Press. This book was released on 2007-09-12 with total page 389 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing the interactions between the different design and construction variables and techniques this book illustrates best practices for constructing economical, long life concrete pavements. The book proceeds in much the same way as a pavement construction project. First, different alternatives for concrete pavement solutions are outlined. The desired performance and behaviour parameters are identified. Next, appropriate materials are outlined and the most suitable concrete proportions determined. The design can be completed, and then the necessary construction steps for translating the design into a durable facility are carried out. Although the focus reflects highways as the most common application, special features of airport, industrial, and light duty pavements are also addressed. Use is made of modeling and performance tools such as HIPERPAV and LTPP to illustrate behavior and performance, along with some case studies. As concrete pavements are more complex than they seem, and the costs of mistakes or of over-design can be high, this is a valuable book for engineers in both the public and private sectors.

Download or read book Where the Weather Meets the Road written by National Research Council and published by National Academies Press. This book was released on 2004-03-31 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weather has broad and significant effects on the roadway environment. Snow, rain, fog, ice, freezing rain, and other weather conditions can impair the ability of drivers to operate their vehicles safely, significantly reduce roadway capacity, and dramatically increase travel times. Multiple roadway activities, from roadway maintenance and construction to shipping, transit, and police operations, are directly affected by inclement weather. Some road weather information is available to users currently, however a disconnect remains between current research and operations, and additional research could yield important safety and economic improvements for roadway users. Meteorology, roadway technology, and vehicle systems have evolved to the point where users could be provided with better road weather information through modern information technologies. The combination of these technologies has the potential to significantly increase the efficiency of roadway operations, road capacity, and road safety. Where the Weather Meets the Road provides a roadmap for moving these concepts to reality.

Download or read book ABCs of z OS System Programming Volume 12 written by Paul Rogers and published by IBM Redbooks. This book was released on 2010-01-28 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Installations today process different types of work with different response times. Every installation wants to make the best use of its resources, maintain the highest possible throughput, and achieve the best possible system responsiveness. You can realize such results by using workload management. This IBM® Redbooks® publication introduces you to the concepts of workload management utilizing Workload Manager (WLM). Workload Manager allows you to define performance goals and assign a business importance to each goal. You define the goals for work in business terms, and the system decides how much resource, such as CPU and storage, should be given to the work. The system matches resources to the work to meet those goals, and constantly monitors and adapts processing to meet the goals. This reporting reflects how well the system is doing compared to its goals, because installations need to know whether performance goals are being achieved as well as what they are accomplishing in the form of performance goals. The ABCs of z/OS® System Programming is a thirteen-volume collection that provides an introduction to the z/OS operating system and the hardware architecture. Whether you are a beginner or an experienced system programmer, the ABCs collection provides the information that you need to start your research into z/OS and related subjects. If you would like to become more familiar with z/OS in your current environment, or if you are evaluating platforms to consolidate your e-business applications, the ABCs collection will serve as a powerful technical tool.

Available in PDF, EPUB and Kindle. Book excerpt: This guide provides guidance to calibrate the Mechanistic-Empirical Pavement Design Guide (MEPDG) software to local conditions, policies, and materials. It provides the highway community with a state-of-the-practice tool for the design of new and rehabilitated pavement structures, based on mechanistic-empirical (M-E) principles. The design procedure calculates pavement responses (stresses, strains, and deflections) and uses those responses to compute incremental damage over time. The procedure empirically relates the cumulative damage to observed pavement distresses.
