Evaluation of High Performance Concrete Pavements in Newport News and Hampton, Virginia

Book Description
This study evaluated the properties of three high performance concrete mixtures placed in a jointed plain concrete paving project on I-64 in Newport News, Virginia, to reduce the shrinkage and improve the flexural strength of the concrete. Two mixtures contained ground-granulated blast furnace slag with 2-inch and 1-inch nominal maximum size (NMS) aggregate, and the third mixture contained Class F fly ash with 1-inch NMS aggregate. Air-entrained paving concretes with satisfactory strength, low permeability, and dimensional stability were prepared using concretes with Class F fly ash or slag and 1-inch or 2-inch NMS aggregates. Slipform pavers satisfactorily placed these concretes. The test sections were in excellent condition after six winters based on a visual survey. Falling weight deflectometer data indicated a better load transfer with the larger aggregate size with everything else being equal. The study also evaluated the maturity method in the continuation of the project on I-64 in Hampton, Virginia. After the evaluation, the pavement was changed to continuously reinforced concrete and the concrete properties were tested in accordance with the recently introduced Guide for Mechanistic-Empirical Design of New and Rehabilitated Pavement Structures (known as the proposed AASHTO M-E Design Guide). In the Hampton portion, a Class F fly ash mixture with the 1-inch NMS aggregate was used. The use of large aggregate, provided the particle shape is acceptable, and uniform combined grading should be specified for concretes with reduced water and cement contents. The maturity method can be used to determine the pavement's readiness for opening to traffic and should be included in the specifications.

Book Description
Internationally, much attention is given to causes, prevention, and rehabilitation of cracking in concrete, flexible, and composite pavements. The Sixth RILEMInternational Conference on Cracking in Pavements (Chicago, June 16-18, 2008) provided a forum for discussion of recent developments and research results.This book is a collection of papers fr
Concrete Pavement Design, Construction, and Performance
Author: Norbert DelattePublisher: CRC Press
ISBN: 1482288486
Category : Technology & Engineering
Languages : en
Pages : 391
Book Description
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.
Recent Developments in Pavement Design, Modeling and Performance
Author: Sherif El-BadawyPublisher: Springer
ISBN: 303001908X
Category : Science
Languages : en
Pages : 205
Book Description
This volume includes a collection of research and practical papers from an international research and technology activities on recent developments in pavement design, modeling and performance, and effects on infrastructure, green energy, technology and integration. Sustainability is increasingly a key priority in engineering practices. With the aging transportation infrastructure and renewed emphasis on infrastructure renovation by transportation agencies, innovations are urgently needed to develop materials, designs, and practices to ensure the sustainability of transportation infrastructure. The volume is based on the best contributions to the 2nd GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2018 – The official international congress of the Soil-Structure Interaction Group in Egypt (SSIGE).
