Hot-Mix Asphalt Railroad Trackbeds

An increase in the thickness of hot-mix asphalt decreases the tensile strain in highway pavements but not necessarily in railroad trackbeds. For railroad underlays with a given combined thickness of ballast and hot-mix asphalt, the tensile strain increases as the thickness of hot-mix asphalt increases, which indicates that the use of ballast is more effective than the use of hot-mix asphalt in reducing tensile strains. That the replacement of ballast by hot-mix asphalt

HOT-MIX ASPHALT RAILROAD TRACKBEDS

The hot-mix asphalt can be used either as an overlay placed directly under the tie or as an underlay placed under the ballast. Because of the similarity between highway pavements and railroad trackbeds, the concept developed for the design of highway pavements is investigated and extended to the design of hot-mix asphalt trackbeds.
