While most pavement engineers design systems with proper drainage, the way to relieve pavements of free water is still a topic of debate. The Federal Highway Administration (FHWA) guidelines stipulate that pavements drain via an asphalt-treated permeable base, filter layers, and collector systems. Drainage layers, though, are often unstabilized or consist of aggregate stabilized with asphalt or cement. Permeability is greater, thus moving water away faster, but structural stability suffers. This article provides an overview of highway drainage tactics being employed by states across the nation (California, Iowa, Minnesota, and Florida) as well as some from foreign countries (Germany and France).
