Using Existing Pavement in Place and Achieving Long Life


Book Description

This report from the second Strategic Highway Research Program (SHRP 2), which is administered by the Transportation Research Board of the National Academies, focuses on improving the ability of highway agencies to design and construct long-lasting highway projects with minimal disruption to the traveling public.







Performance of Bare and Resurfaced JRCP and CRCP on the Illinois Interstate Highway System, 1991 Update


Book Description

Two previous studies on the survival of bare and asphalt-overlaid concrete pavements on the Illinois Interstate highway system were updated to reflect the performance of the pavements through 1991. The Illinois Interstate system consists of about 1750 miles of 10-inch jointed reinforced concrete pavement ORCP) and continuously reinforced concrete pavement (CRCP) ranging in thickness from 7 to 10 inches. As of 1991, about 60 percent of these pavements had been overlaid with asphalt concrete (AC), ranging in thickness from 1.5 to 6 inches. Data for the survival analysis were retrieved from the Illinois Pavement Feedback System database. Both in-service life and accumulated 18-kip ESALs at rehabilitation were estimated for bare pavements categorized by type, thickness, and D cracking susceptibility, and for overlaid pavements categorized by overlay thickness, overlaid pavement type, and D cracking susceptibility. The results show the effects of D cracking, traffic level, pavement type, pavement thickness, and overlay thickness on performance of bare and resurfaced concrete pavements.




Case Studies in Asphalt-overlaid Concrete Pavement Evaluation and Rehabilitation


Book Description

This report demonstrates the application of the AC/PCC pavement evaluation and rehabilitation guidelines to several in-service case studies. The case studies were used throughout this research study to develop, test, and revise the evaluation and rehabilitation guidelines. The product of this iterative development effort is a step-by-step process for selection and design of appropriate rehabilitation strategies for AC/PCC pavements. The case study analyses also demonstrate the difficulty of complete project-level evaluation, the need for accurate and up-to-date data (especially condition data), and the importance of experience and good engineering judgment in the many decisions which must be made regarding pavement rehabilitation planning and design.










Portland Cement Concrete Overlays


Book Description

This report presents the latest information on the design, construction and performance of portland cement concrete (PCC) overlays. It describes the four types of PCC overlays that are commonly used in highway pavement applications: bonded PCC overlays, unbonded PCC overlays, conventional whitetopping and ultra-thin whitetopping. Recommended applications, critical design elements, current overlay design methodologies, recommended construction practices, and performance highlights are described for each overlay type. Information is also provided on the selection of PCC overlays as possible rehabilitation alternatives for existing pavements. Taken together, this document addresses the current "state of the technology" of PCC overlays placed on both existing PCC pavements and on existing hot-mix asphalt pavements.




Structural Behavior of Asphalt Pavements


Book Description

Structural Behavior of Asphalt Pavements provides engineers and researchers with a detailed guide to the structural behavioral dynamics of asphalt pavement including: pavement temperature distribution, mechanistic response of pavement structure under the application of heavy vehicles, distress mechanism of pavement, and pavement deterioration performance and dynamic equations. An authoritative guide for understanding the key mechanisms for creating longer lasting pavements, Structural Behavior of Asphalt Pavements describes the intrinsic consistency between macroscopic performance and microscopic response, structure and material, as well as global and local performances, and demonstrates the process of pavement analyses and designs, approaching science from empirical analyses. - Analyzes the external and internal factors influencing pavement temperature field, and provide a review of existing pavement temperature prediction models - Introduces a "Bridge Principle through which pavement performance and fatigue properties are consolidated - Defines the intrinsic consistency between macroscopic performance and microscopic response, structure and material, as well as global and local performance - Summaries the mechanistic response of pavement structure under the application of heavy vehicle, distress mechanism of pavement, pavement deterioration performance and dynamic equations, and life cycle analysis of pavement
