It has been pointed out to me that the rules for SVloads are different from HB loads and therefore the load files need modifying.
New files can be downloaded here, but please note that they are only valid (for the time being) if there is enough fill at the critical poisition to ensure that the two wheels on an axle act together. That means 1.15m of fill at about 1/4 span. If this isn't the case it may be necessary to use a resticted bridge width to make sure the load is sufficient.
