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 »

Compaction

Compaction is the process by which the volume of air in an HMA mixture is reduced by using external forces to reorient the constituent aggregate particles into a more closely spaced arrangement. This reduction of air volume produces a corresponding increase in HMA density (Roberts et al., 1996[1]). Compaction is the greatest determining factor in … Read more »

Grader placing UTPB_2

Water is sometimes called the “universal solvent” because given enough time, it will dissolve just about anything. Even something that appears pretty permanent, like an asphalt pavement, can be eroded and damaged by water action. Roads are still exposed to the elements, however, and it would be virtually impossible to keep a pavement from coming … Read more »

broom texture

What does the texture of a road mean? Imagine if you were a car driving on the road, how would you describe the feeling? Would you say it was harsh and scratchy? Or does it feel slick and slippery? Somewhere in between is probably just right, where the road feels pretty smooth but there’s still … Read more »
