Hot Mix Asphalt Railway Trackbeds - University of Kentucky

2009-9-17  The uses of Hot-Mix Asphalt as a subballast layer within railroad track structures for new trackbed construction and trackbed maintenance applications have grown steadily in the United States during the past 25 years. The asphalt layer (termed underlayment) is used in lieu of the conventional all-granular subballast layer as indicated in Figure 1. The underlayment is typically placed 5 to 8 in. (125 to 200 mm) thick and 12 ft (3.6 m) wide. A base mix having a 1.0 in (25 mm) maximum aggregate size, that is slightly “over asphalted”, with about 0.5 percent additional asphalt binder than normally specified for a highway pavement mix is considered the ideal mix for railway trackbed

Hot-Mix Asphalt (Bituminous) Railway Trackbeds: In-Track ...

2014-12-9  The use of a layer of hot mix asphalt within the track substructure, in lieu of conventional granular subballast, is becoming widely utilized to provide ideal properties to the crossing (Rose, 2011). Perhaps thousands of crossings have been rehabilitated or initially constructed using this procedure. The basic process involves removing the old crossing surface and track panel followed by excavating the underlayment mixture of ballast, subballast, and subgrade to the required depth. These are replaced with a compacted layer of hot mix asphalt (termed asphalt underlayment), a compacted layer of ballast, a new track panel, and a new crossing

To retain its compaction properties between the asphalt plant and being laid on the road, the asphalt mix cannot be too hot or too cold. Its temperature has to be just right. “Temperature is the key,” said Jim Scherocman, a Cincinnati-based asphalt consultant with 54 years experience in the business.
