Pavement Interactive

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 »

Aggregate

“Aggregate” is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium (such as water, bitumen, portland cement, lime, etc.) to form compound materials (such as asphalt concrete and portland cement concrete). By volume, aggregate generally accounts for 92 to 96 percent of HMA … Read more »

Survey: 60% of Respondents Using e-Construction Tools Reported On-Time Deliveries for Most Projects

To better assess the impacts of e-Construction on US transportation construction deliveries, transportation software company Pavia Systems recently commissioned an e-Construction survey of project owners, owner’s representatives and contractors who build our roads, streets, highways and bridges. The survey results are remarkable, to say the least, as they reveal exceptional performance among e-Construction adopters in … Read more »
