University of California, Davis Department of Civil and Environmental Engineering Fall 2006 J. Harvey, instructor NAME____________________________________________________________ ECI 179 - PAVEMENT ENGINEERING Mid-Term Conditions: closed book, closed notes. NOTE: “Brief” means BRIEF, no credit for lots of words that don’t give me additional information specifically asked for in the question!!! Part I (1 point each) True-False Circle the correct answer as to whether the statement is T-true or F-false. The statement must be completely true to be considered true. 1. T F Alkali-silica reaction is a problem that can occur in portland cement concrete, and is caused by a reaction between the aggregate and the high pH in the cement. 2. T F Particle size gradation, absolute viscosity and penetration are the tests used for the Unified Soil Classification System. 3. T F The transverse joints in continuously reinforced concrete pavement must be cut before the concrete has cured too much, or else undesired irregular cracking will occur. 4. T F An asphalt concrete mix becomes stiffer when subjected to lower temperatures and when subjected to shorter load durations 5. T F In flexible pavements, all of the pavement layers are designed to help carry the load, and each layer must reduce stresses at the top of the layer below to an acceptable level.
