Select the row with the appropriate pavement temperature, temperature trend, and <br />weather conditions. <br />2. Select the column that has the type of material you are using. <br />3. Find the box where the row and columns intersect to find the application rate. These <br />rates are not fixed values, but rather the middle of a range to be selected and <br />adjusted by your agency according to your local conditions and experience. <br />4. Compare those values to the calibration chart for your truck. <br />5. Dial the correct setting for the rate indicated on the Application Rate Guidelines. <br />6. If you are not treating a 24-foot-wide road (typical two -lane road), adjust the rate as <br />follows: for application on a single lane, cut rates in half. For an 18- foot -wide road, use <br />3/4 of the listed rate (i.e., multiply rate by 0.75). <br />• <br />For extra copies of one or more of these inserts, please visit the Minnesota LTAP Web site at www.mnitap.umn.edu /publications. <br />
