507.01 Description.
This work consists of furnishing properly distributed asphalt material followed by a uniform application of aggregate for building a riding surface, improving the surface friction of a roadway, sealing cracks in the roadway, reducing the rate of oxidation of a surface mixture, or as an interlayer to delay or reduce the occurrence of reflective cra cking. Asphalt Surface Treatment (AST), sometimes referred to as “chip seal,” consists of a specified emulsion applied “cold” or polymer modified asphalt material applied “hot,” at the temperature range specified in Table 507 -1 for cold applications or Tab le 507 -2 for hot applications, respectively. The application rates of asphalt material and aggregates will vary with aggregate size and existing roadway conditions but, for bid purposes only, shall meet the requirements of Table 507 -1 or Table 507 -2. The engineer will review the actual application rates.
507.02 Materials.
507.02.1 Asphalt: Use asphalt materials complying with Section
1002 that are Approved Material List produ cts. Comply with Table 507 -1 or 507 -2. Take samples of asphalt material in the presence of the engineer's representative. The engineer's representative will immediately take possession of the samples.
507.02.2 Aggregates: Aggregates shall comply with 1003.07 and
Table 1003 -15. Use Approved Material List aggregates shown herein or as designated on the plans.
