Abstract:

In this report the effect of surface infiltration of frac sand and heavy axle loads (HALs) were studied for their impact on the ballast layer. ; Different combinations of ballast and fracking sand were constructed to observe long term trends of deformational behavior. The results ; of HAL tests show that for all ballast an increased rate of strain accumulation averaging 0.07%/MGT for every 30 kip car load increase ; occurs. The results of the surface spillage tests show an average increased rate of strain accumulation averaging 0.05%/MGT, ; 0.13%/MGT, and 0.31%/MGT for AREMA ballast #24, #4A, and #5 respectively, for a 7% increase in gravimetric water content. Modeling ; conducted by the WiscRail ® program show and increased maintenance interval of 50-100%. The increased shipment of frac sand for ; hydrocarbon recovery will affect the rail lines on which it is shipped. Increased monitoring and maintenance will need to be conducted for ; the lines to operate in an efficient manner
