This book was released on 2004 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A two-lane continuously reinforced concrete pavement was built in Blacksburg, Virginia, as a part of Virginia's Smart Road. One of the lanes is 12 ft wide, and the other is 14 ft wide. The additional 2 ft was part of the shoulder. Below the concrete pavement is a 3-in-thick open-graded drainage layer (OGDL); one section is asphalt stabilized, and the other section is cement stabilized. The concrete pavement was cured by a curing compound except that the 12-ft lane was also covered with plastic and straw because of concerns with cold ambient temperature. The objective of this project was to determine the material properties of the concrete, instrument the pavement, monitor construction practices, and monitor the performance of the pavement over 4 years. The concrete had high early strength, low permeability, and high shrinkage. The average crack spacing was more than 3 ft, indicating satisfactory performance. In general, cracks were wider when they were further apart, but the differences in crack spacing and width were variable and small in some cases and could not be correlated after 4 years. The end sections had less cracking than the interior sections of the pavement. There were fewer cracks and more space between cracks in the 12-ft lane and fewer cracks in the pavement over the asphalt-stabilized OGDL. This was attributed to a better cure in the 12-ft lane and to a lower friction over the asphalt-stabilized base. No changes to the specifications were recommended as a result of the study findings.

This book was released on 2004 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: An increasing number of agencies, academic institutes, and governmental and industrial bodies are embracing the principles of sustainability in managing their activities. Life Cycle Assessment (LCA) is an approach developed to provide decision support regarding the environmental impact of industrial processes and products. LCA is a field with ongoing research, development and improvement and is being implemented world-wide, particularly in the areas of pavement, roadways and bridges. Pavement, Roadway, and Bridge Life Cycle Assessment 2020 contains the contributions to the International Symposium on Pavement, Roadway, and Bridge Life Cycle Assessment 2020 (Davis, CA, USA, June 3-6, 2020) covering research and practical issues related to pavement, roadway and bridge LCA, including data and tools, asset management, environmental product declarations, procurement, planning, vehicle interaction, and impact of materials, structure, and construction. Pavement, Roadway, and Bridge Life Cycle Assessment 2020 will be of interest to researchers, professionals, and policymakers in academia, industry, and government who are interested in the sustainability of pavements, roadways and bridges.
