Pavement
An overview of the history and basic concepts involved in road pavements. This includes coverage of common pavement types organized into two groups, flexible pavements and rigid pavements. … Read more »
Materials
Pavements are a conglomeration of materials. These materials, their associated properties, and their interactions determine the properties of the resultant pavement. Thus, a good understanding of these materials, how they are characterized and how they perform, is fundamental to understanding pavement. … Read more »
Testing
An overview of concepts related to pavement testing. A number of different test procedures are used to evaluate construction materials, paving mixtures, and finished pavements. … Read more »
Construction
Construction quality is crucial to the long-term pavement performance. Construction factors such as surface preparation, placement, joint construction and compaction/consolidation have an overwhelming effect on pavement performance, which cannot be ignored or compensated for in mix or structural design. … Read more »
QC & QA
Quality has become one of the most important consumer decision factors in the selection among competing products and services (Montgomery, 1997). This is true not only for individual consumers but also for large corporations, government organizations and the taxpaying public as a group. Thus, quality is a key factor in pavement construction. … Read more »
Design
The goal of pavement design is to specify the characteristics required for quality performance for a given application. Two key components are mix design and structural design. These processes must also take into account external parameters including subgrade characteristics, traffic loading, and the environment. … Read more »
Maintenance and Rehabilitation
The combined effects of traffic loading and the environment will cause every pavement, no matter how well-designed/constructed to deteriorate over time. … Read more »
Pavement Management
"Pavement management" refers to a systematic process of maintaining, upgrading and operating a network of pavements and involves three major components: the pavement life cycle, the costs associated with this life cycle and pavement management systems. … Read more »

Life-Cycle Cost Analysis
All new construction, reconstruction, rehabilitation and maintenance projects should employ some level of economic evaluation to determine the most cost effective method and timing. The FHWA report FHWA-SA-98-079, Life-Cycle Cost Analysis in Pavement Design defines life-cycle cost analysis (LCCA) as: “…an analysis technique that builds on the well-founded principles of economic analysis to evaluate the … Read more
