A bridge with an E rating is supposed to be good for a train of two? The culvert section had been distorted significantly during installation, to the extent that the village decided to barricade it off in case of collapse.

The first is the primary source for this calculation. Figure 1 below illustrates the axle load and spacing breakdown for both HS20 and HS25 design trucks. A majority of what will be covered in this article goes into design loadding.

I installed reference points in the tunnel for receiving tapered ends of a measuring device using dial deflection gauges as used in a machine shop. I suspect these are relatively slight compared to effect of longitudinal loads and would be considered part of the factor of safety rather than explicitly included.

Posted by Overmod on Sunday, November 11, There are loasing references you can use to answer your question. Member since September, 6, posts. The second loaded axle is spaced far enough away that loadihg will have a negligible impact on the pipe design.

Thank for your help. I was able to get one planned measuring event where I could control just which axle was over the reference location. We must change cooper E80 to only one load or just push it on the line?
