SPECIFICATIONS

I. MATERIALS

A. CURBS

1. Curbs shall be 4" x 4' Interlocking Precast Red Dog Curbs.

2. A Typical Track will require Approx. 3000 Linear Ft. of Red Dog Curbing.

B. BASE COURSE

1. Local Road Base Material (Crushed Rock, Caliche, etc.)

Caution: Base must have sufficient fines to facilitate compaction.

C. TOP COURSE

1. Red Dog Track Topping as manufactured by Red Dog Track, Inc., Strawn, Texas.

2. Red Dog Track Topping weights approx. 2400 pounds per cubic yard before compacting. After compaction, one ton will cover approx. 225 square ft., one inch deep.

II. APPLICATION OF MATERIALS

A. SUBGRADES AND ELEVATIONS

1. Specifications concerning preparation of subgrades, the layout, area drainage, and elevations shall be furnished by the owner’s architect or engineer. The track should always be built above surrounding grade level to allow for proper drainage.

B. BASE COURSE

1. Placement of the base materials shall be done only after the subgrade is finished.

2. When using Interlocking Precast Curbs, base should be 1 ft. wider on each side of the finished track.

3. Spread Base material to a thickness which will allow 10 percent compaction. Use of light blade equipment will be allowed.

4. Compact base course.

C. CURBS

1. Curbs shall be set in accordance with the design drawings. True to line and dimensions.

2. Curbs shall be installed in desired location. The top of the curbs shall be run to proper grade line. After all curbs have been placed, Anchors shall be installed to secure curbs. A partial backfill on the outsides of the curbs shall be applied by hand to prevent misalignment of curbs.

D. TOP COURSE

1. Topping shall be delivered onto the base course with light equipment, protecting curbs and base course. Light blade equipment shall be used to distribute topping.

2. After spreading top course and screening to required bulk thickness to allow 10 percent compaction, the top course can be rolled with equipment of not more than 500 pounds per square foot on bearing surface.
