Designing Operations of Geocomposite Membrane Installation in Flexible Pavements
MetadataShow full item record
Geosynthetics are currently being incorporated in flexible pavement systems to improve their performance. However, geosynthetics must be used in the correct application and installed properly in order to produce good results. One of the newly developed geosynthetics is geocomposite membrane that thought to provide strain energy absorption and a moisture barrier. This research discusses the application of discrete-event simulation (DES) to design and analyze the installation of geocomposite membranes in flexible pavements. Data collected from two test sections at the Virginia Smart Road in Blacksburg, Virginia was used for modeling and analysis. STROBOSCOPE, a programming language designed for modeling complex operations, was used as the simulation engine. The process used in the development of simulation models is discussed. A number of installation alternatives were studied and simulated to examine their practicality and to investigate their productivity, resource utilization, and unit cost.
