models, screed extensions make it possible to pavewidths up to 24 feet in a single pass.Cutoff Shoes. — Cutoff shoes (fig. 16-47) have theopposite function of screed extensions. They are metalplates inserted into the screed to reduce the width of themat being placed.Bevel End Plates.—Bevel end plates (fig. 16-48)are used to bevel the edge of the mat. On some models,the shoes can be set at any one of three positions:vertical, 30 degrees, or 45 degrees.Tons Per HourThe equation, used to compute the amount ofasphalt that can be layed with a paver per hour, is asfollows:Figure 16-47.—Cutoff shoes.16-42WhereL =W =D =146 =60 =2,000 =Figure 16-48.-Bevel end plates.Feet per minute. The NCF uses 11 feet perminute for planning purposes.Width of the paver screedDepth or thickness of compacted matThis number represents the approximateweight of 1 cubic foot of compactedhot-mix asphalt60 minutes in 1 hourThere are 2,000 pounds in 1 tonExample: The required tonnage of hot-mix asphaltfor a project is 800 tons. The screed of the paver is setat 10 feet, and the depth of asphalt is 2 inches. Estimatethe amount of asphalt that can be laid per hour.By planning and estimating the amount of hot-mixasphalt that can be laid per hour, you are able to tell theasphalt plant exactly how much hot-mix asphalt isrequired to be delivered per hour or per day.MAINTENANCEAs an Equipment Operator, it is your responsibilityto coordinate the proper operation, care, use, adjusting,
