Ballasted track systems with rubberized asphalt coatings and related methods

A track system comprising:

• a supporting structure;
• ballast, configured to support a plurality of track ties, supported by the supporting structure;
• a plurality of track ties, configured to support a pair of rails, supported by the ballast;
• a pair of rails supported by the plurality of track ties;
• and
• a layer of rubberized asphalt coating disposed as an interface between the ballast and the supporting structure, the rubberized asphalt coating having bituminous binder, crumb rubber particles, and stone aggregate;
• wherein resiliency of the layer of rubberized asphalt coating permits particles of the ballast in direct contact with the layer of rubberized asphalt coating to move elastically relative to each other while inhibiting abrasion of adjacent ones of the particles of the ballast against each other and the against supporting structure.
