"WELDED" BALLAST. NEW CONCEPT IN TRACK STABILIZATION

It is shown how system, involving use of elastomeric compound to bind ballast section into a shock-absorbing mass, gives favorable results in prototype tests. A new type of polymer was developed and perfected for use as the bonding agent at the Rubber Chemical Div of Phillips Petroleum Co. The stress-strain tests showed that the polymer without vulcanization has more than ten times the strength of conventional rubbers. The tests at the AAR Research Center consisted of determining the behavior of the test tracks under static and repeated loads.
