Common use of APPLICATION EQUIPMENT Clause in Contracts

APPLICATION EQUIPMENT. Use asphalt application equipment that meets Article 600-5 of the 2012 Standard Specifications. Apply aggregate by the use of a self-propelled, pneumatic-tire aggregate spreader capable of maintaining a specified rate with a uniform application for the width of asphalt material being covered. Tailgate spreaders will not be permitted. Areas that are inaccessible to the aggregate spreader shall be covered by hand spreading or other acceptable methods. The grades of emulsion shall be CRS-2L or CRS-2P. The target rates of application and the temperature that the emulsion is to be applied shall be as shown in Table 660-1 or as directed by the Engineer Base the required rates of application on the volume of material at the application temperature.
