This 58-page publication provides general guidelines for establishing a field quality control program for the production and placement of roller-compacted concrete (RCC). Prepared primarily for the use of RCC in dam and overtopping spillway applications, the manual can also be useful for heavy-duty pavement and storage area type projects. Tables and figures are included to illustrate various key elements in a typical QC program. Also included are several sample data recording forms and worksheets.

A revised and current comprehensive guide to Full-Depth Reclamation (FDR) using cement. FDR is a roadway rehabilitation process that recycles the materials from deteriorated asphalt pavement, and, with the addition of portland cement, creates a new stabilized base. The addition of a new concrete or bituminous riding surface completes the FDR process, providing a new roadway structure using recycled materials from the failed pavement.

This document describes the step-by-step process, from initial site investigation, to mix design, and construction. A recommended construction specification for FDR is included.

Cement-treated base (CTB) is a general term that applies to a mixture of native soils and/or manufactured aggregates with measured amounts of portland cement and water. The soil is then compacted and cured to form a strong, durable, and frost-resistant paving material. Other descriptions such as soil-cement base, cement-treated aggregate base, or cement-stabilized base are sometimes used.

This document provides a basic guide on the use of cement-treated base (CTB) for pavement applications. It provides an overview on the design and construction of CTB for both mixed-in-place and central plant mixed operations. A suggested construction specification is also included.

Roller-compacted concrete (RCC) is an economical, fast-construction candidate for many pavement applications. It has traditionally been used for pavements carrying heavy loads in low-speed areas because of its relatively coarse surface. However, in recent years its use has expanded into commercial areas and local streets and highways.

This guide provides owner-agencies, contractors, material suppliers, and others with a thorough introduction to RCC and its many applications. Based on current research and best practices, the guide provides detailed overviews of RCC properties and materials, mixture proportioning, structural design, and production and construction considerations, plus troubleshooting guidelines and an extensive reference list for more comprehensive information.

This guide provides a clear, concise, and cohesive presentation of cement-bound materials options for 10specific engineering pavement applications: new concrete pavements, concrete overlays, pervious concrete, precast pavements, roller-compacted concrete, cement-treated base, full-depth reclamation with cement, cement-modified soils, recycled concrete aggregates, and repair and restoration.

Each application is presented as a method for meeting specific design and construction objectives that today’s pavement practitioners must accomplish. The benefits, considerations, brief description, and summary of materials, design, and construction requirements, as well as a list of sustainable attributes, are provided for every solution.

This guide is intended to be short, simple, and easy to understand. It was designed so that the most up-to-date and relevant information is easily extractable. It is not intended to be used as a design guide for any of the applications identified herein. Recommendations for additional information that can provide such details are given at the end of each solution discussion.

The intended audience is practitioners, including engineers and managers who face decisions regarding what materials to specify in the pavement systems they design or manage. The audience also includes city and county engineers, along with the A/E firms that often represent them, and state DOT engineers at all levels who are seeking alternatives in this era of changing markets.

This Guide to Full-Depth Reclamation (FDR) with Cement is a product of the National Concrete Pavement Technology Center (CP Tech Center) at Iowa State University’s Institute for Transportation, with funding from the Portland Cement Association. The guide provides a concise discussion of all aspects of selecting, designing, and constructing a reclaimed, cement-stabilized asphalt base in preparation for a new pavement surface layer.

 

As the nation’s infrastructure ages, agencies at all levels are tasked with maintaining and rehabilitating their infrastructure. Sustainable engineering technologies in pavement rehabilitation, such as full-depth reclamation (FDR), could be the answer for agencies in their quest to provide taxpayers with high-quality infrastructure while being good stewards of public funds. Full-depth reclamation of asphalt pavement is a rehabilitation method that involves recycling an existing asphalt pavement and its underlying layer(s) into a new base layer. The FDR process begins with using a road reclaimer to pulverize an existing asphalt pavement and a portion of the underlying base, subbase, and/or subgrade. Usually the pulverized material is uniformly blended with an additional stabilizing material such as cement to provide an upgraded, homogeneous material. Finally, the stabilized material is compacted in place with rollers. The result is a stiff, stabilized base that is ready for a new rigid or flexible surface course. This guide introduces the FDR with cement process and discusses issues related to project selection, design, construction and testing/quality control.

Fuel consumption due to pavement-vehicle interaction (PVI) is an essential part of life-cycle assessment (LCA) of pavement systems. In general, roughness and deflection of a pavement are considered as the main contributors to PVI. Some estimates attribute up to 70% of greenhouse gas emissions (GHG) to PVI due to the unavoidable deflection of pavements when subjected to vehicle load.

Various empirical studies have looked at the impact of pavement deflection on fuel consumption; however, their main focus has been on a binary material view of asphalt versus concrete pavement, with no consideration of the relationship between pavement deflection and its structure and material.

Research conducted by MIT used a mechanistic approach to draw a relationship between pavement structure and material with its deflection, and creates a link between pavement properties and the impact of PVI on fuel consumption. To achieve this goal, the work involved a model calibration and validation for pavement deflection values, estimated fuel consumption caused by the deflection basin, and compared the results to that of existing field data. The use of a first-order mechanistic model allowed for the identification of key design parameters to down-size fuel consumption due to PVI. Results from this modeling predicted that asphalt overlays need to be 25-60% thicker to display the same fuel consumption performance as concrete.

This free webinar will review the various empirical studies that have been conducted related to PVI and discuss some of the uncertainties associated with these studies. A mechanistic model will be presented that considers the role deflection plays in fuel consumption and results from the model will be compared to some of the more recent empirical PVI studies.
