Hydraulic and Environmental Behavior of Roadway Millings in Highway Shoulder Applications

Maryland State Highway Administration (SHA) desires to evaluate the hydraulic behavior of roadway millings (also called recycled asphalt pavement, RAP) placed on highway shoulders. RAP is obtained by removing and reprocessing the existing asphalt pavement and is commonly reused in highway construction (FHWA 2012). RAP is typically produced through milling operations, which involves the grinding and collection of the existing hot mix asphalt. Keller (2013) defined the roadway millings (RAP) as "the fine particles (generally from dust to less than an inch or so) of bitumen and inorganic material that are produced by the mechanical grinding of bituminous concrete surfaces."
