Pavement Management for Airports, Roads, and Parking Lots PDF Download Ebook. Mo Y. Shahin emphasizes sound, cost-effective management rather than emergency repairs. This comprehensive volume offers practical guidelines on evaluating and managing pavements for airports, municipalities, and commercial real estate firms.
Extensive appendices serve as field manuals for identifying all types of pavement distress and their causes, and hundreds of photographs facilitate accurate pavement evaluation. Author shows chemical reaction between alkalis and certain reactive silica minerals which form a gel. The gel absorbs water, causing expansion which may damage the concrete and adjacent structures.
Alkalis are most often introduced by the portland cement within the pavement. ASR cracking may be accelerated by chemical pavement deicers. Other topics include shoving of asphalt pavements, light can tilting, slab faulting, joint misalignment, and extrusion of joint seals or expansion joint fillers. Because ASR is material-dependent, ASR is generally present throughout the pavement section. Coring and concrete petrographic analysis is the only definitive method to confirm the presence of ASR. The following should be kept in mind when identifying the presence of ASR through visual inspection.
This text offers the reader with a necessary update to the book. The update presents changes to the Pavement Condition Index (PCI) distresses that have been approved and published by ASTM in 2010. The ASTM changes are summarized.
