You can summarize information damages roadside FE <br /> gathered from your truck logs into application rates for your <br /> area. Be aware, though, that sample rate charts vary greatly vegetation. <br /> from one area to another, and most are very high. Make it a e <br /> goal to reduce application rates while keeping our roads safe. a <br /> You can reduce rates by following anti-icing and other strate- <br /> gies covered in this field handbook <br /> S- <br /> e .3 <br /> GUIDELINES FOR DETERMINING APPLICATION RATES <br /> • Sand /salt mix isn't advised but may help in some situa- <br /> tions such as freezing rain. <br /> • Always plow before applying chemical. For reapplication, <br /> start with the lowest rate in the range. <br /> • High traffic volume will work salt into the snow and aid in <br /> melting —so use a lower rate. a <br /> • Higher traffic speeds will blow salt off the road and hinder <br /> melting —so increase use of prewetted materials. <br /> • Use sand for short -term traction only. It will never melt <br /> anything. <br /> • For application on a single lane, cut rates in half. For an 18- <br /> foot -wide road, use 3+ of the listed rate (Le., multiply rate <br /> by 0.75). <br /> • It is usually not cost - efficient to apply salt (sodium chlo- @ <br /> ride) at pavement temperatures below 15° F. . r. <br /> n d <br /> o H <br /> o <br /> o <br /> gt co . <br /> m a <br /> � m <br /> � 6 <br /> 15 <br /> 66 <br />
