Its intended audience is engineering students at the undergraduate and junior graduate levels. The Concrete Criteria Rating system is designed to evaluate existing concrete conditions and prioritize concrete replacement. The concrete conditions are determined by various characteristics such as vertical separation, severe ponding, fracture, spalling and missing concrete. As the concrete continues to contract, the joints will open-providing room for the concrete to expand in hot weather and in moist conditions. When a concrete pavement needs reconstruction or major rehabilitation, rubblizing the concrete and topping it with an asphalt overlay is the easiest, lowest-cost, and most effective way to rehabilitate the pavement in the shortest amount of time.
