Louisiana Experimental Base Project
The Louisiana Experimental Base Project is a research study evaluating the design and performance characteristics of three types of base courses as incorporated into comparable flexible pavement systems on a full-scale test road. Fourteen different test sections were constructed to evaluate the study variables, which included base course type (soil cement, stabilized sand clay gravel, and asphaltic concrete), design life (5, 10, and 15 years), and surface thickness (3.5 and 15.5 inches). The test road is U.S. Route 71, south of the city of Alexandria. Fundamental engineering properties of paving materials were determined in the laboratory using a variety of tensile and compressive tests utilizing repeated loading techniques. Layer moduli were also determined from field deflection tests using Dynaflect data. Field monitoring of serviceability and structural number were compared to trends. Measured values of serviceability decline, cracking, and rutting were also compared to predicted values using the VESYS IIIA program. Observations are made regarding materials properties determination for design, distress mechanisms affecting performance, and performance prediction models.
