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 »

Surface Preparation_FI

Surface Preparation

Before a pavement is placed the surface to be paved must be prepared. Adequate surface preparation is essential to long-term pavement performance. Pavements constructed without adequate surface preparation may not meet smoothness specifications, may not bond to the existing pavement (in the case of overlays) or may fail because of inadequate subgrade support. Surface preparation … Read more »

When a road is built, we naturally want it to be durable. Roads can be built using different materials, but the quality of the end product depends on how it is constructed, not just the inherent properties of the materials themselves. So what does durability mean, and how can we achieve it? In general, durability … Read more »

Tarped load

Before a pavement is constructed, the materials that go into it must be mixed together and hauled to the job site. Trucking operations are a key part of getting the pavement mix to the right place. Both asphalt pavement mixes and portland cement concrete (PCC) mixes need to be properly loaded, transported, and unloaded in … Read more »
