Existing pavement, curb and sidewalk needing removal will be saw-cut into sections/blocks or perimeter cut and demolished using breaker/hammer and then removed by appropriate equipment. Concrete slurry resulting from concrete saw operation will be vacuumed and removed from site. All materials removed during demolition will be removed from site.

Subgrade will be excavated as needed and either FlexBase for pavement/curbs or a Fine Grade FlexBase for sidewalks will be added & compacted as necessary to ensure desired compaction/surface preparation is achieved & lines are brought to the required grades for placement of new concrete.

All drive, curb and sidewalk paving shall be designed to have a minimum compressive strength of 3,500 psi at twenty-eight (28) days and placed at a depth of 5” for sidewalk, 6” for pavement and 12” for curbs. Concrete will have a camel hair broom finish. Note: A curing compound will be applied during the hot months of the year (with daily temperatures exceeding approx. 90°) to protect it from drying out too quickly resulting in a weaker finish with higher tendencies toward cracking and spalling.

Clean existing area with “Power Broom” and/or “Billy Goat” as needed. Apply a tack coat over entire surface area. Install 2” of Hot Asphalt Type “D” topping. Roll to compaction with a steel wheel vibratory roller.

Perimeter of area to be saw cut & removed to a depth of 6” and sub-grade compacted. Tack and install a 4” binder base of Hot Asphalt Type “B” followed by a topping base of Hot Asphalt Type “D” rolled with steel wheel vibratory roller to a compacted depth of approx. 2” and flush with adjacent gutter.

Existing asphalt to be pulverized to a depth of 9” adding 6″ of Portland cement by weight finishing with water & compaction to depth of 6”. Tack coat to be placed over entire surface of newly prepared subgrade. Hot asphalt type “D” will then be placed and rolled with steel wheel vibratory roller to a compacted depth of approx. 2”.

Clean existing area with “Power Broom” and/or “Billy Goat” as needed. Treat areas of petroleum saturation & prime with a heavy-duty bonding agent to promote surface adhesion. Apply 2 coats of Coal Tar Pitch Emulsion protective coating at 1 gallon per 45 sq. ft. Six pounds of sand to be added per 1 gallon of coal tar. GemSeal Fed/Spec Pavement Sealer will be mixed at 4 gallons per 100 gallons of coal tar.
