temperature at the time of dumping into the spreader will be higher than that specified herein. Rejection will occur any loads that are below minimum temperature, that have crusts of cold unworkable material, or that have been wet excessively by rain. Hauling over freshly laid material is not permitted.

D. General Requirements for Use of Bituminous Spreaders: The range of temperatures of the mixtures at the time of spreading shall be between 275 and 350 degrees F.
