"Materials-Related Concrete Pavement Distresses" Webinar Scheduled
March 7, 2016

Materials-related distress (or MRD) are not related inadequate design or construction, and instead, are related to the materials properties and environments to which they are exposed. MRD’s may be seen in either hardened concrete pastes or aggregates and pastes.

The webinar will describe thee specific distresses, as well as their causes/mechanisms, time of appearance, and solutions for preventing or reducing distresses all together.

The webinar will cover physical mechanisms (i.e., freeze/thaw deterioration of hardened cement paste; de-icer scaling/deterioration; and freeze-thaw deterioration of aggregate) and chemical mechanisms (i.e., alkali-silica reactivity (ASR); alkali-carbonate reactivity (ACR); sulfate attack (both internal and external) and corrosion of embedded steel. For aggregates, the course will cover ASR and D-cracking, as well as distresses occurring because of other contaminants.

The American Concrete Pavement Association will award 1.0 professional development hour (PDH) to those wishing to complete an optional “evidence of learning exam” following the webinar.

This 1.0 hour training event is scheduled for Wednesday, March 9th, 2016. The event will be held at 1:00 p.m. to 2:00 p.m. (Eastern) | Noon to 1:00 p.m. (Central) | 10:00 a.m. to 11:00 p.m. (Pacific). Although this is a 1.0 hour module, please allow extra time — as much as 1.5 hours total — for questions and administrative details.
