Placing a tray or a mat of known area on the surface and weighing the quantity of stabilizing agent deposited on it after spreading can be used to verify the application rate. The overall check can be conducted by checking the distance or area over which a truckload of a stabilizer of known weight is spread.</p><p><strong>Accuracy and Precision</strong></p><p>Information on the accuracy and precision of these methods was not documented in references.</p><p><strong>Adequacy of Coverage</strong></p><p>According to PCA (1980), for a spot check, a canvas is placed in an area of 1 m² (1 yd²). The overall check can cover the distance or area over which a truckload of cement of known weight is spread.</p><p><strong>Implementation Requirements </strong></p><p>It needs to be able to weigh the truck before and after application for the overall method. It needs to be able to weigh and measure a canvass for the spot check.</p><p><strong>General Comments </strong></p><p>According to the Army and Air Force (1994), field personnel should be aware of quantities of stabilizer required per linear foot (or meter) or per square yard (or meter) of pavement. Spot checking can be used to assure that the proper quantity of cement is being applied, by using a canvas of known area or, as an overall check, the area over which a known tonnage has been spread.</p></p>
