APPLICATION EQUIPMENT Clause Samples

APPLICATION EQUIPMENT. Use epoxy application equipment, which is equipped with or capable of the following: Precisely metering the two components in the ratio of proportion recommended by the manufacturer. Producing the required amount of heat at the mixing head and gun tip. Maintaining temperatures within the tolerances recommended. Gauges for each proportioning pump so that any pressure difference can be easily monitored. A minimum 24" long static mixer unit for proper mixing of the two components of the epoxy marking material. Each component of the epoxy pavement marking shall be in a homogeneous state prior to mixing, Have the capability to totally mix component A with component B immediately prior to the marking application. Have the capability to spray both yellow and white pavement marking material and have the equipment mounted on a truck of sufficient size and stability with an adequate power source to produce uniform lines of the specified dimension. A metering device to register the accumulated installed footage for each gun

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.

Emulsion Target Rates have +/- 0.03 gal/sy tolerance limit. C. Grades of emulsion shall be CRS-2L. D. Application temperatures shall be 160-170ºF. 660-8 CONSTRUCTION METHODS (A) Asphalt Seal Coat Use the type of seal coat as required by the contract. Seal coat aggregates shall be drained of free moisture and dust free before use. Place the seal coat in full-lane widths. Adjust the aggregate rates to provide a sufficient quantity of cover material to be spread over the surface of the seal coat preventing traffic damage, where it is necessary to permit traffic on sections of a completed seal coat. Perform rolling of each layer immediately after the aggregate has been uniformly spread. Rolling will consist of at least 3 complete coverages with one pneumatic-tire roller followed by at least one complete coverage with a 5 to 8 ton steel-wheel roller. All roller coverages shall be completed within 5 minutes of the asphalt emulsion being placed. Do not allow crushing of the aggregate or picking up of the material by the rollers. The use of a combination steel-wheel and pneumatic-tire roller will be permitted instead of the 5 to 8 ton steel-wheel roller. After the aggregate is thoroughly seated, broom all excess aggregate off of the surface of the seal coat after 3 days but no more than 7 calendar days. Traffic may be permitted on the seal coat immediately after the rolling is complete. Clean driveways, ditches, turn lanes, and areas adjacent to the AST construction of excess aggregate, excess emulsion run off, over spray or debris from construction. Blotting sand may be required as directed by the Engineer and shall be applied in accordance with Section 818 of the 2012 Standard Specifications. The construction of the various types of seal coats will be in accordance with the following additional requirements:
