or

C. No other material will be acceptable unless approved by Owner/Architect/Engineer in writing ten (10) days prior to bid date.

2.02 MATERIALS

1. A hot applied elastomeric crack/joint sealant for asphaltic and concrete pavements.

2.03 EQUIPMENT

A. Melt down the sealant in a kettle or melter constructed as a double boiler. The space between the inner and outer shells filled with high flash point heat transfer oil or other indirect heating means.

B. The kettle to be used must have constant agitation any time material is over three hundred (300) degrees F. The kettle must have temperature-monitoring capabilities.

C. Roofing kettles or other direct fired melters are not acceptable for these materials.

PART 3 EXECUTION

3.01 EXAMINATION

A. Inspect existing pavement for conditions and defects that will adversely affect quality of work and which cannot be put into acceptable condition through normal preparatory work as specified.

B. Starting installation constitutes contractors acceptance of surface as suitable for installation.

3.02 PREPARATION

A. Cracks

1. Remove vegetation and all incompressible materials from cracks and joints by means of hot compressed air lance. (Other methods such as routing w/compressed air cleaning may be substituted at engineer’s specification. Under ANY circumstances compressed air used for cleaning MUST be oil free.

Cracks and joints less than one quarter (1/4) inch in width must be routed to a minimum one half (1/2) inch by one half (1/2) inch in shape.
