After hauling a load of asphalt mix, only using part of the load, toploading the cleanup scrap, dumping off on the recycle pile hours after loading hot mix I went on to haul some class 5 gravel. I noticed that the first load was a bit heavier than expected but I paid it no mind. The next load was more than a ton heavy and the third was almost identical to the second. After getting out and looking inside the box I found that I had a sizable chunk of asphalt setup hard in the front corner of the box. My attempts to clean out the box with a shovel failed. However, with the assistance of an outstanding excavator operator we were able to get it knocked loose.
It is no wonder why my weights were off by 1500# or so. I’ll add this lesson to the file. When hauling mix always dump the entire load either in the paving machine or on the recycling pile at the job site.
