Available in PDF, EPUB and Kindle. Book excerpt: The permeability of asphalt-concrete pavements to air and water appears to be a primary factor in controlling pavement durability. Early investigators (Hveem (1) and McKesson (2)) were concerned with obtaining permeabilities low enough to prevent liquid water from entering the base but, at the same time, high enough to allow water vapor to escape. Pfeiffer (3) and a few others have shown the main cause of pavement hardening to be the action of oxygen from the atmosphere. He has also shown that the influence of air is dependent on the voids content at the time of construction. In this case, the permeability of the pavements is proportional to the voids content. More recently, Ekse and Zia (4) proposed using permeability for construction control and discussed the importance of permeability with respect to durability. They described a method for measuring air permeabilities of pavement cores and suggested that their equipment could be adapted to measure the permeability of pavements in place. The device works on the principle of a decaying pressure as air flows through the pavement. McLaughlin and Goetz (5) have also devised a method for measuring air permeability of pavement cores. With it, they have studied the relationship between permeability and a laboratory durability test (loss in sonic modulus caused by alternate freezing and thawing). They found a correlation between voids and permeability and showed that asphalt content, compactive effort, and aggregate gradation are factors affecting permeability.

Available in PDF, EPUB and Kindle. Book excerpt: "TRB's National Cooperative Highway Research Program Report 747: Guide for Conducting Forensic Investigations of Highway Pavements explores a process for conducting forensic investigations of pavements that is designed to help understand the reasons behind premature failures or exceptionally good performance. The process also allows for the collection of data for use in developing or calibrating performance-prediction models. The report includes example forms and checklists for use during the conduct of an investigation. These forms can be modified to suit the particular requirements and procedures for the agency. The example forms are included with the print version of the report in CD-ROM format." --Publisher description.
