4.1 BORDER: • A 7.5" deep x 6" wide concrete curb border shall be constructed at the base of the fence to contain the new stone and asphalt base. Curb shall be poured into place such that it is immediately adjacent to the inside edge of the fence line. Height of border shall be 7.5" inches to contain the new stone base and asphalt paving 4.2 CRACK TREATMENT: • Cracks shall be filled with acrylic patch binder crackfill material to flush with the existing surface. Crackfil material shall be installed full depth. After crackfil material has dried, joint retarding fabric Mirafi Miractac shall then be overlaid on top of the crack area. Fabric shall be 1’ wide to minimize reflection of the old cracks into the new base. • After completion of crack repair, a stone layer shall be installed directly on top of the existing courts. Stone shall be pug mix. Stone shall be laser graded and compacted into place. Stone shall be rolled in order to achieve 95% of maximum dry density. No variation of the finished stone base shall be greater than ½" of the desired elevation. Average depth of stone after compaction shall be 4 inches. The slope of the stone base shall be 1% in order to shed water adequately after a rain. 4.3 BASE INSTALLATION: • The asphalt base shall be installed in two layers. The first layer shall be 2.0 inches of binder type asphalt, Tennessee Department of Transportation specification “B”. The thickness of the asphalt layer is measured after compaction. After this first layer of asphalt is installed, a second layer is measured after compaction. After this first layer of asphalt is installed, a second layer of asphalt 1.5 inch in thickness shall be installed over the court area. Specification of the finish layer of asphalt shall be TDOT commercial surface “CS”. Rolling of asphalt shall be done so as to accomplish maximum compaction of the asphalt base without any displacement of the mat. All roller marks, took marks, or imperfections in the asphalt mat shall be rolled out. The planarity of the finished asphalt surface shall not vary more than ¼” in ten feet when measured with a 10’ straight edge. Court shall be flooded or shall be observed after a hard rain in order to ascertain that it drains water in accordance with standard industry guidelines. Any puddles holding more than 1/8” of eater after adequate drying (1 hour after a rain event on a 70 degree day) of the court surface shall be pathed prior to application of any surface coatings. 4.4 FENCING: • Existing fence shall not be replaced. The existing fence mesh shall be taken down, stored, and reused. We will build the curb and then reinstall the wire behind the new curb. With the height of the new court, there will be a 7.5" step up to the courts and the fence height will be 7.5" lower than original. 4.5 HARWARE: • If existing net post sleeves are intact and not heaving, they shall remain and new steel extension collars will be added to account for the new elevation. If they are in bad shape, existing net post foundations shall be excavated. New net post foundations shall be installed in concrete footings 4' in depth and 18" in diameter. New tennis nets and net posts shall be installed following completion of job. Net strap anchors 1' in diameter and 2' in depth shall be poured in concrete to secure the net strap.
