Flexible Pavements — Materials and Pavements

Description. The Flexible Pavements Program focuses on issues related to the design, construction, and maintenance of asphalt pavements. Currently studies are underway that include design of long-life full-depth pavements, design of overlays that retard reflection cracking, rubblization of existing concrete structures, full-depth reclamation, and use of new technologies to measure the quality

Curing Concrete, Chapter 12 ce.memphis.edu

On flat surfaces, such as pavements and floors, concrete can be cured by ponding. Earth or sand dikes around the perimeter of the concrete surface can retain a pond of water. Ponding is an ideal method for preventing loss of moisture from the concrete; it is also effective for main-taining a uniform temperature in the concrete. The curing

How is the design life of a reinforced concrete structure

The problem with reinforced concrete is that eventually the reinforcing will corrode, expand in size, and cause the concrete to crack. There can also be issues with the aggregates that are used. How can a designer calculate and, by contract, guarantee the life of a reinforced concrete structure?

Long Lasting Concrete Patch askthebuilder

Permanent concrete repairs are possible, well, nearly permanent. It's possible to expect a 20 30 year life expectancy from a properly executed repair. That isn't so bad if you ask me. The trick to a long-lasting concrete repair lies in bonding the new material to the old material.

On asphalt pavements, the material used is a proprietary thermoplastic. This material is similar to the extruded thermoplastic products used for standard pavement markings, but is formulated a bit differently to tailor it to this application. On concrete pavements, two-part epoxy systems are used for the coating.
