Description

Concrete pavements are important for a range of applications—from lightly loaded streets to heavily loaded roadways and airfield facilities. It is becoming an established practice in the United States to require that concrete pavements provide low-maintenance service lives of 40 or more years irrespective of the application. Long-life concrete pavements have been attainable for a long time (as evidenced by the fact that a number of very old pavements remain in service); and recent advances in design, construction, and concrete materials technology give us the knowledge and technology needed to consistently achieve what we already know to be attainable. To achieve long life, pavements must not exhibit premature failures and must have a reduced potential for cracking, faulting, spalling, and materials related distress. However, even though it is not a widespread occurrence, concrete pavements once in a while exhibit premature or early-age failures, reducing the service life of the facility at a cost to the owners and facility users, as well as creating a potential for litigation between the different parties involved in the affected projects. This course addresses pavements that may experience shorter life services resulting from poor concrete pavement placement practices and side effects of unbalanced or poorly designed concrete mixtures. Examples will be presented to show efforts to troubleshoot poor pavement quality and valid reasons to employ petrography lab testing to help identify sources of pavement problems.

Learning Objectives

1. Describe the effect that changes in the chemistry of concrete mixtures have on set-time of concrete, including the relationship of aluminates and sulfates in concrete.

2. Explain how petrography is used to troubleshoot damage in deteriorated concrete.

3. List things to know before performing a forensic investigation on deteriorated concrete pavements that may include petrography.

4. Describe some examples of poor construction quality on concrete pavements, including poor practices with dowel bar placement, under and over consolidation, pavement edge blowout, surface texturing, and curing.
