Book excerpt: The United States Air Force is responsible for 1.7 billion square feet of concrete and asphalt airfield pavement which requires millions of dollars to maintain and repair each year. As funding constraints become more stringent, Air Force engineers must ensure the proper strategic approach is taken to manage airfield pavement maintenance and repair activities. The United States Air Forces strategic approach is to use pavement asset management principles to prolong the life of the airfield pavement assets and to maintain the desirable operational missions level of service. One step in pavement asset management, which is often overlooked or not routinely performed, is to provide feedback on the effectiveness of the total pavement management system and alignment of design methods, specifications and policies with an agencys goals. This research provides feedback to the United States Air Force regarding its current pavement management policies by conducting analysis on pavement distresses. Pavement distresses are a key variable collected to assess a pavements condition. To assist in providing feedback, analysis was performed to determine which airfield pavement distresses are causing the largest cumulative reduction in pavement conditions across the entire United States Air Force enterprise. Linear cracking, joint seal damage, large patches, shattered slabs, joint spalling, small patches, and alkali silica reactivity are the portland cement concrete airfield pavement distresses causing the largest summative reduction in pavement condition. Longitudinal and transverse cracking, weathering, block cracking, and alligator cracking are the asphalt concrete airfield pavement distresses causing the largest cumulative reduction in pavement condition. Each distress was statistically analyzed to determine if pavement structure or climatic variables are influencing the likelihood of each distress occurring under current policies. The distresses were analyzed independently and the results suggest the United States Air Forces current design and management policies are not fully compensating for the impacts of pavement structural and climatic factors.

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.
