Book Description
The Concrete Pavement (CP) Road Map is a comprehensive and strategic plan for concrete pavement research that will guide the investment of research dollars for the next several years. It will result in technologies and systems that help the concrete pavement community meet the paving needs of today, and the as-yet unimagined paving challenges of tomorrow. In short, the CP Road Map will result in a new generation of concrete pavements for the 21st century.
Material and Construction Optimization for Prevention of Premature Pavement Distress in PCC Pavements

Book Description
In Phase I, the research team contacted each of 16 participating states to gather information about concrete and concrete material tests. A preliminary suite of tests to ensure long-term pavement performance was developed. The tests were selected to provide useful and easy-to-interpret results that can be performed reasonably and routinely in terms of time, expertise, training, and cost. The tests examine concrete pavement properties in five focal areas critical to the long life and durability of concrete pavements: (1) workability, (2) strength development, (3) air system, (4) permeability, and (5) shrinkage. The tests were relevant at three stages in the concrete paving process: mix design, preconstruction verification, and construction quality control. In Phase II, the research team conducted field testing in each participating state to evaluate the preliminary suite of tests and demonstrate the testing technologies and procedures using local materials.

Book Description
Paper 1: Cement content of the concrete mortar was determined by neutron activation and analysis of ca49 produced in the calcium in the portland cement. Paper 2: It was realized that the number of tests per variable made in an earlier report might have been insufficient to explore fully the suitability of mixing for only a short time. When this supplementary study was conducted, a greater number of strength specimens per variable of mixing time was made to obtain suitably complete data for short mixing times. Paper 3: The basic elements of concrete pavement construction costs are briefly discussed and evaluated. a cost analysis for an assumed project in a midwestern location is given to illustrate the effects of variations in design and construction practices on construction costs.
Real-time Smoothness Measurements on Portland Cement Concrete Pavements During Construction

Book Description
"TRB's second Strategic Highway Research Program (SHRP 2) Report S2-R06E-RR-1: Real-Time Smoothness Measurements on Portland Cement Concrete Pavements During Construction explores real-time smoothness measuring technologies for concrete paving. For the purposes of the report, real-time smoothness refers to measuring and evaluating the concrete pavement surface profile during construction along the paving train while the concrete surface is still wet. The report also includes draft suggested specifications and guidelines related to the use of technologies that allow paving crews to measure smoothness in real time. The results of Renewal Project R06E will be incorporated into an electronic repository for practitioners, known as the NDToolbox, which will provide information regarding recommended technologies for the detection of a particular deterioration. The NDToolbox is in the process of being created by SHRP 2 Renewal Project R06A, which has released SHRP 2 Report S2-R06A-RR-1: Nondestructive Testing to Identify Concrete Bridge Deck Deterioration that identifies nondestructive testing technologies for detecting and characterizing common forms of deterioration in concrete bridge decks. Renewal Project R06E, which produced SHRP 2 Report S2-R06E-RR-1, is one of seven follow-on projects to SHRP Renewal Project R06 that produced SHRP 2 Report S2-R06-RW: A Plan for Developing High-Speed, Nondestructive Testing Procedures for Both Design Evaluation and Construction Inspection, which examines existing and emerging nondestructive evaluation (NDE) technologies and their current state of implementation to satisfy the NDE needs for highway renewal."--Publisher description.
Design, Construction, and Maintenance of PCC Pavement Joints

Pages : 60
Book Description
This synthesis report will be of special interest to pavement engineers and pavement construction and maintenance personnel responsible for portland cement concrete (PCC) pavement joints. Still pertinent information from NCHRP Synthesis 19 (1973), as well as new or updated information in the areas of joint design, construction, and maintenance are included. This report of the Transportation Research Board records the state of the practice with respect to the design, construction, and maintenance of PCC pavement joints. In addition, information on joint materials and sealing, the control of water on and in pavements, and the evaluation of pavement joint performance is provided.

Strategic Plan for Improved Concrete Pavement Surface Characteristics
Author: Publisher:
ISBN:
Category : Pavements
Languages : en
Pages : 98
Book Description
Surface characteristics represent a critical issue facing pavement owners and the concrete paving industry. The traveling public has come to expect smoother, quieter, and better drained pavements, all without compromising safety. The overall surface characteristics issue is extremely complex since all pavement surface characteristics properties, including texture, noise, friction, splash/spray, rolling resistance, reflectivity/illuminance, and smoothness, are complexly related. The following needs and gaps related to achieving desired pavement surface characteristics need to be addressed: determine how changes in one surface characteristic affect, either beneficially or detrimentally, other characteristics of the pavement, determine the long-term surface and acoustic durability of different textures, and develop, evaluate, and standardize new data collection and analysis tools. It is clear that an overall strategic and coordinated research approach to the problem must be developed and pursued to address these needs and gaps.
