Book excerpt: The Virginia Department of Transportation (VDOT) currently follows pavement design procedures for all new and rehabilitated pavements based on the 1993 AASHTO Guide for Design of Pavement Structures. VDOT's Materials Division is in the process of implementing the Mechanistic-Empirical Pavement Design Guide (MEPDG) procedure via AASHTOWare Pavement ME Design software. The MEPDG uses mechanical properties of pavement materials for pavement structural design. The mechanistic-empirical design process presents a major change in pavement design from the 1993 AASHTO design guide. It calculates pavement responses through mechanistic analysis based on inputs such as traffic, climate, and materials properties to predict the pavement damage or distress over time for both asphalt and concrete pavements. The purpose of this study was to evaluate the mechanical properties of cement-treated aggregate (CTA) and recommend values for use in AASHTOWare Pavement ME Design software. The field construction of CTA was monitored, and samples were collected for laboratory determination of the compressive strength, modulus of elasticity, and modulus of rupture. Tests with the falling weight deflectometer were conducted to back-calculate the CTA modulus of elasticity, and field cores were collected for testing compressive strength and modulus of elasticity. CTA gained strength with increases in cement content, and the increase in strength and the strength level depended on the aggregate properties, such as the resilient modulus of unbound aggregate. All measured properties were highly variable. VDOT would need to implement a strength-based CTA design to be able to use the required mechanical properties of CTA in the MEPDG system. The study recommends using a target design 7-day compressive strength of 600 to 800 psi. Such strength corresponds well with VDOT's current pavement design practice in accordance with the 1993 AASHTO design guide. CTA mechanical properties were suggested based on this target strength. Most of the default values presented in the MEPDG are considered reasonable. In addition, the values recommended for use in the MEPDG are 1.5 million psi for modulus of elasticity and 200 psi for modulus of rupture.

Available in PDF, EPUB and Kindle. Book excerpt: Concrete made using mineral cements, the raw materials which on earth are practically endless, is known as one of the oldest building materials and during the last decades of the twentieth century has become a dominant building material for general use. At the same time, the requirements of the quality of concrete and its performance properties, in particular compressive strength, durability, economical efficiency, and low negative impact of its manufacture on the environment have not yet been completely met. Bearing these requirements in mind, researchers and engineers worldwide are working on how to satisfy these requirements. This book has been written by researchers and experts in the field and provides the state of the art on recent progress achieved on the properties of concrete, including concrete in which industrial by-products are utilized. The book is dedicated to graduate students, researchers, and practicing engineers in related fields.

Available in PDF, EPUB and Kindle. Book excerpt: Sustainable Construction Materials: Recycled Aggregate focuses on the massive systematic need that is necessary to encourage the uptake of recycled and secondary materials (RSM) in the construction industry. This book is the fifth and the last of the series on sustainable construction materials and like the previous four, it is also different to the norm. Its uniqueness lies in using the newly developed, Analytical Systemisation Method, in building the data-matrix sourced from 1413 publications, contributed by 2213 authors from 965 institutions in 67 countries, from 1977 to 2018, on the subject of recycled aggregate as a construction material, and systematically analysing, evaluating and modelling this information for use of the material as an aggregate concrete and mortar, geotechnics and road pavement applications. Environmental issues, case studies and standards are also discussed. The work establishes what is already known and can be used to further progress the use of sustainable construction materials. It can also help to avoid repetitive research and save valuable resources. The book is structured in an incisive and easy to digest manner and is particularly suited for researchers, academics, design engineers, specifiers, contractors, and government bodies dealing with construction works. Provides an exhaustive and comprehensively organized list of globally-based published literature spanning 5000 references Offers an analysis, evaluation, repackaging and modeling of existing knowledge that encourages more responsible use of waste materials Provides a wealth of knowledge for use in many sectors relating to the construction profession, including academia, research, practice and adoption of RSM

It has been written by a team of leading international experts from the UK, USA, Canada, Israel, Germany, Denmark, South Africa, Italy and France. Research studies over recent years in the field of cement science have focused on the behaviour of the interfaces between the components of cement-based materials. The techniques used in other areas of materials science are being applied to the complex materials found in cements and concretes, and this book provides a significant survey of the present state of the art.

Available in PDF, EPUB and Kindle. Book excerpt: This project focused on the evaluation of the feasibility of using crushed portland cement concrete (CPCC) materials in TxDOT applications. Special interest was given to the use of CPCC fines passing the No.4 sieve. The research approach for exploring potential applications was divided into two ways as follows: . paving applications: flexible base, cement treated base, and HMA bond breaker; and . non-paving applications: portland cement concrete, flowable fill, backfill, and embankment. Much of the research effort was devoted to a laboratory test program for material characterization. The test program identified aggregate properties, mix design properties, basic mechanistic properties, workability, and moisture susceptibility of the applied mixtures containing crushed concrete materials. Although the use of crushed concrete materials generally resulted in increased water demand and decreased workability, test results indicated that crushed concrete materials are highly feasible to use in the selected applications. However, CPCC fines were determined not to be suitable for the reproduction of portland cement concrete because the loss of workability was so severe in this application. Based on the results of the test program, recommendations and revised specifications, which allow for the use of CPCC fines, are provided for the selected applications: flexible base, cement treated base, HMA bond breaker, flowable fill, backfill, and roadway embankment.
