This book was released on 1977 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the development of guidelines for determination of maintenance and repair (M and R) needs of airfield pavements. The guidelines are based on the pavement condition index (PCI) and other condition indicators, including rate of deterioration, cause of deterioration, load carry capacity, skid resistance/hydroplaning, surface roughness, and extent of previous M and R. The M and R methods were divided into three general categories: routine, major, and overall. The mean pavement PCI was found to relate strongly to M and R needs represented by these three M and R categories. M and R zones for use in selecting the appropriate M and R category were established based on the mean pavement PCI. Other condition indicators are used to further aid in the selection of feasible M and R alternatives. Recommended M and R methods for the different distress types and severity levels were developed. Economic analysis procedures were developed for comparing M and R alternatives. The airfield pavement condition survey and rating procedures have been successfully field-tested. Performing the condition survey according to these procedures does not require expensive equipment; only a measuring wheel and straightedge are required. The results can be used to rate pavement condition and to select M and R requirements for all pavement features of the airfield.

Shahin and published by . This book was released on 1981 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents development of the Airfield Pavement Management System (APMS), a computerized system for analyzing airfield pavements. The system provides: (1) a method for determining feasible maintenance and repair (M & R) alternatives for a given pavement feature, (2) a procedure for performing economic analyses to compare various M & R alternatives for a given pavement feature, and (3) a procedure for forecasting the Pavement Condition Index and key distresses as a consequence of applying an M & R alternative to a particular pavement feature. APMS now consists of seven modules designed to: (1) perform evaluation summary, (2) perform localized repair analysis, (3) evaluate the consequences of localized repair, (4) evaluate the consequences of other M & R, (5) perform cost analysis, (6) perform benefit analysis, and (7) perform budget optimization.

This book was released on 1977 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Air Force has for several years been actively engaged in the development of a Pavement Maintenance Management System. The first accomplishment of this study was the development of improved procedure for determining the relative condition of airfield pavements. These improved procedures are presented in detail in this report. These procedures were developed during FY 75 and 76 and validated by field tests during FY 76 and 77. Two conferences, attended by Command Pavement Engineers from all Major Commands, have been held at Tyndall AFB, Florida (30 Nov - 2 Dec 1976, 18 - 20 October 1977), to discuss and revise these procedures. It was the consensus of the attendees at these conferences that these procedures provided vastly improved methods for determining the relative condition of airfield pavements. Thus, CEEDO was requested, during the conference held in October 1977, to publish, in some form, instructions for the use of these procedures as soon as possible. As a result this technical report is being published in the same format as that used for Chapter 3, 'Airfield Pavement Condition Survey Report, ' AFR 93-5. The Air Force Civil Engineering Center (AFCEC), at Tyndall AFB, Florida, has the responsibility for revising AFR 93-5. It is recommended that the information presented in this report be used as a basis for revision of Chapter 3, AFR 93-5. (Author).

This book was released on 1979 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents maintenance and repair (M & R) guidelines and economic analysis procedures for determining optimum repair strategies for a given airfield pavement. The procedures consist of data collection, condition evaluation, identification of feasible M & R alternatives, performing economic analysis, and selection of the optimum M & R alternative. The primary data to be collected are pavement distress types, severities, and amount. This information is then used to compute a pavement condition index (PCI), which is based on a scale of 0 to 100 and measures the pavement structural integrity and surface operational condition. Pavement evaluation is performed through a stepwise procedure which is largely dependent on the PCI and distress data, since they have been found to correlate highly with M & R needs. Other direct measurements, such as profile roughness, hydroplaning potential, and load-carrying capacity, are also included in the evaluation procedure. Guidelines for rational determination of feasible M & R alternatives are presented, based on the results from the pavement evaluation. Included in the guidelines are acceptable alternatives for the localized repair of different distress types at different severity levels. Economic analysis is performed among feasible M & R alternatives, using the present worth method. The optimum alternative is selected based on the results of the economic analysis, mission, and policy.

Shahin and published by . This book was released on 1979 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistical prediction models for pavement condition index (PCI) and key distresses have been developed for asphalt and jointed concrete pavements. The models were developed based on field data collected during FY76 through FY78 from 19 airfields throughout the United States. The field data included traffic, climate, pavement structure and material properties, and previous maintenance. Prediction models were developed for concrete and asphalt pavements, respectively. These models represent the first iteration of the consequence models needed to help pavement engineers select the most economical maintenance and repair (M & R) strategies and to help management efficiently allocate repair funds. Two workshops were held to determine information required by Air Force Command and Base engineers to efficiently manage airfield pavement M & R. The workshops were attended by many Command and Base engineers, as well as representatives from the Air Force Design Center and the Directorate of Management Systems. Computer and information requirements were defined and implementation alternatives for a computer-aided pavement management system were developed as a result of these workshops. (Author).

Book excerpt: This report describes the development and verification of a pavement condition index (PCI) for rating the condition of jointed concrete and asphalt-or tar-surfaced airfield pavements. The PCI, which measures airfield pavement structural integrity and surface operational condition, is calculated based on measured pavement distress types, severities, and densities obtained during an inspection of the pavement. Volume II of this report presents distress types, descriptions, severity levels, and measurement criteria for use in performing the pavement inspections.

This book was released on 1984 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive data were collected from 327 airfield pavement features at 12 U.S. Air Force bases. The data, which provided a wide range of information on designs, materals, traffic, and climate, were used to develop PCI and key distress prediction models for both asphalt-concrete and jointed-concrete-surfaced pavements. Four satisfactory models were developed for predicting PCI for PCC and AC/PCC pavements, corner breaks in PCC pavements, and reflection cracking in AC/PCC pavements. Additional data were collected from 101 airfield pavement features at five of the Air Force bases originally surveyed to evaluate the four prediction models. The evaluation showed that the PCI prediction models are satisfactory. The reflection cracking model also provided reasonable prediction of eight pavement features. However, verification of the corner break model showed that it has a high standard deviation of prediction. Evaluation of the models for each of the five bases showed that predictions for some of the bases were much better than others, possibly because some of the material properties, climatic factors, and traffic conditions in certain bases were not well represented in the overall model. Thus, it was concluded that localized modeling could provide much more accurate predictions.
