A decking system provides a surface upon which traffic may travel. Drivable decking surfaces can support heavy vehicles, such as tanks. Exemplary decking systems include a first module, a second module, a first upper fastening assembly, a first lower fastening assembly, a second upper fastening assembly, and a second lower fastening assembly. These fastening assemblies can secure the first module and the second module together. Decking systems may also include side ramp assemblies and/or end ramp assemblies, and such ramp assemblies can be coupled with a decking platform. Fastening assemblies may include a pin, a first clip, and a second clip.
