The Louisiana Experimental Base Project is a research study evaluating the design/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 in order to evaluate the study variables. The variables of the experimental design included base course type (soil-cement, stabilized sand clay gravel, and black base), design life (5, 10, and 15 years), and surface thickness (three and one-half and five and one-half inches (8.9 and 14.0 cm)). The test road is U.S. Route 71 south of the City of Alexandria.
This interim report documents the design, construction, as-built properties of the components and total road section, and current traffic trends at the Louisiana Experimental Base Project.
Over the course of the last 17 years, approximately 12 different studies have shown the potential for the use of geosynthetic materials (geogrids and ...
The effects of excessive water within pavement structural sections has been shown to decrease the servicelife of our nation’s roadways. Some of the ...
