Implementation of Curing, Texturing, Subbase, and Compaction Measurement Alternatives for Continuously Reinforced Concrete Pavement

This report evaluates four different subbase types, two different concrete mix designs (a standard Texas Department of Transportation gradation and an optimized gradation), three different curing compounds, and four different surface textures that researchers tested on a new section of continuously reinforced concrete pavement. In particular, researchers found: (1) The instrumented roller package was effective in locating areas of low stiffness in subgrade soils. (2) Falling weight deflectometer and dynamic cone penetrometer data can be used to evaluate the stiffness of stabilized subbases before concrete paving commences. (3) The proposed curing compound evaluation protocol not only considered the moisture loss throughout the maturing process of concrete, but also introduced the relative humidity, surface abrasion strength, and water content of cured concrete samples to assess the curing compound effectiveness. (4) It appears that the use of geotextile between Continuously Reinforced Concrete Pavement (CRCP) and the subbase is questionable and may not provide the desired pavement performance. (5) The ConcreteWorks program was effectively calibrated using the data collected from this project.
