CONCRETE SIDEWALKS:

I.) GENERAL

1.1 PROVIDE CONCRETE SIDEWALKS TO THE LINES AND GRADES SHOWN WITHIN THESE CONTRACT DOCUMENTS.

1.2 THE CONSTRUCTION OF ITEMS UNDER THIS SPECIFICATION SHALL BE COORDINATED WITH OTHER ITEMS OF CONSTRUCTION SOAS TO BE CONSTRUCTED IN PROPER SEQUENCE.

II.) PRODUCTS

2.1 PROVIDE CLASS "A" CONCRETE AS DEFINED BY SECTION 701 & 702 OF THE SOUTH CAROLINA DEPARTMENT OF HIGHWAYS &PUBLIC TRANSPORTATION "STANDARD SPECIFICATIONS FOR HIGHWAY CONSTRUCTION", LATEST EDITION.

2.2 THE CONCRETE USED SHALL BE COMPOSED OF A MIXTURE OF PORTLAND CEMENT, COARSE AND FINE AGGREGATES, ANDWATER. ALL CONCRETE SHALL HAVE A 28 DAY COMPRESSIVE STRENGTH OF 3,000 POUNDS PER SQUARE INCH AS SPECIFIEDWITHIN THESE CONTRACT DOCUMENTS.

A. ADDITIVES: FIBER MESH ADDITIVE SHALL BE UTILIZED FOR CONCRETE REINFORCING.

2.3 BASE MATERIAL: NATURALLY OR ARTIFICIALLY GRADED MIXTURE OF NATURAL OR CRUSHED GRAVEL, CRUSHED STONE, ANDNATURAL OR CRUSHED SAND; ASTM 2940/D 2940M; EXCEPT WITH 100 PERCENT PASSING A 1-INCH (25-mm) SIEVE AND NOT MORETHAN 8 PERCENT PASSING A NO. 200 (0.075-mm) SIEVE.

2.4 RIGID PVC JOINTING MATERIAL: PROVIDE TRIPSTOP TS100S RIGID PVC TYPE-S JOINTING MATERIAL WITH Ø14 x 10" HOT-DIPPED

GALVANIZED PINS AND MANUFACTURER PRODUCED PEGS FOR FORMING.

2.5 PROVIDE NO. 3 CRUSHED POULTRY OYSTER SHELLS FOR APPLICATION OF OYSTER TABBY FINISH REQUIRED TO MATCH EXISTINGCONCRETE FINISH.

2.6 PRIOR TO STARTING WORK, OBTAIN ENGINEER'S APPROVAL OF METHODS, EQUIPMENT, TOOLS, AND MACHINERY FOR HANDLINGMATERIALS AND EXECUTING THE WORK. ENGINEER'S APPROVAL IS FOR ABILITY TO PERFORM WORK ONLY.

III.) EXECUTION

3.1 THE SUBGRADE SHALL BE EXCAVATED AND NEW BASE MATERIAL PLACED IN LAYERS NOT MORE THAN 8 INCHES IN LOOSE DEPTHAT OPTIMUM MOISTURE CONTENT. COMPACT EACH LAYER TO 95 PERCENT OF MAXIMUM DRY UNIT WEIGHT ACCORDING TOASTM D 698 STD. PROCTOR. COMPACTED BASE MATERIAL SHALL BE OF DEPTH REQUIRED BY THESE CONTRACT DOCUMENTSAND SHAPED TO LINE, GRADE, AND CROSS-SECTION PRIOR TO THE CONCRETE BEING PLACED. THE SUBGRADE SHALL BE MADETO THE REQUIRED DEPTH AND WIDTH THAT WILL PERMIT THE INSTALLATION AND BRACING OF FORMS.

3.2 ALL SOFT AND YIELDING MATERIAL SHALL BE REMOVED AND REPLACED WITH ACCEPTABLE MATERIAL, WHICH SHALL THEN BEREPLACED PER 3.1 REQUIREMENTS ABOVE.

3.3 FORMS FOR SIDEWALKS SHALL BE OF WOOD OR METAL OF A SECTION SATISFACTORY TO MEET THE DESIGN CONDITIONS. THEREINFORCING, IF REQUIRED, SHALL BE PLACED IN POSITION AS SHOWN ON THE DRAWINGS. ALLOW FORMS TO REMAIN IN PLACEFOR A MINIMUM OF 24 HOURS AFTER CONCRETE PLACEMENT.

3.4 THE SECTIONS OF SIDEWALKS SHALL BE DIVIDED INTO BLOCKS BY USE OF A TRIPSTOP PVC JOINT INSTALLED DURING FORMINGWORK. JOINTS SHALL BE PLACED SO AS SPACING BETWEEN JOINTS DOES NOT EXCEED THE LESSER OF 1.5 TIMES THE WIDTHOF WALKWAY OR A MAXIMUM OF 10'-0" SPACING, BEING FORMED. INSTALLATION OF RIGID PVC JOINTS WITH PINS AND PEGSSHALL BE PER MANUFACTURER'S RECOMMENDED INSTALLATION FOR SIDEWALK WIDTHS

3.5 DO NOT PLACE CONCRETE UNTIL SUBGRADE AND FORMS HAVE BEEN CHECKED FOR LINE AND GRADE. MOISTEN SUBGRADE TOPRODUCE A UNIFORM DAMPENED CONDITION AT TIME CONCRETE IS PLACED.

3.6 EXPANSION JOINTS FORMED BY 1/2 INCH PREMOLDED EXPANSION JOINT FILLER SHALL BE PLACED IN ALL SIDEWALKS ADJACENTTO EXISTING CONCRETE. ALL PREMOLDED EXPANSION JOINT FILLER SHALL BE CUT TO FULL WIDTH AND LENGTH OF THEPROPOSED CONSTRUCTION AND SHALL EXTEND TO WITHIN 1/2 INCH OF THE TOP OR FINISH GRADE. EXPANSION JOINT FILLEROF THE THICKNESS INDICATED SHALL BE INSTALLED BETWEEN CONCRETE SIDEWALKS AND FIXED STRUCTURES AND ADJACENTCONCRETE SECTIONS.

3.7 CONCRETE SURFACES SHALL BE PROTECTED FROM THE SUN BY ACCEPTABLE MEANS OF CURING. THE CURING PROCESSSHALL BEGIN AS SOON AS MARRING OF THE NEW CONCRETE WILL NOT OCCUR. WHEN A WATER CURE IS USED THE CONCRETESHALL BE KEPT CONTINUOUSLY WET FOR 72 HOURS. IF THE CONTRACTOR ELECTS TO USE A MANUFACTURED CURINGMEMBRANE, IT SHALL BE APPLIED UNDER PRESSURE BY MECHANICAL SPRAYERS AT THE RATE RECOMMENDED BY THEMANUFACTURER, BUT IN NO CASE AT A RATE LESS THAN ONE GALLON TO EACH 150 SQUARE FEET.

3.8 FINISH CONCRETE SURFACE VARIATIONS SHALL BE NOT MORE THAN 1/8 INCH UNDER A TEN FOOT LONG STRAIGHTEDGE.PROVIDE CONCRETE WORK OF THIS SECTION WITH A WOOD FLOAT FINISH, UNLESS OTHERWISE SPECIFIED. THE EDGES OF ALLCONCRETE SURFACES SHALL BE ROUNDED WITH AN EDGING TOOL HAVING A RADIUS OF 1/4 INCH.

3.9 SECTIONS OF SIDEWALKS THAT ARE DAMAGED DURING CONSTRUCTION AND BEFORE FINAL ACCEPTANCE SHALL BE REPLACEDIN A SATISFACTORY MANNER BY THE CONTRACTOR AT NO EXPENSE TO THE OWNER.

3.10 AFTER THE CURING PROCESS HAS BEEN COMPLETED, CONCRETE WALKS AND CURBS SHALL BE BACKFILLED WITH SUITABLEMATERIAL AND THEN TAMPED AND COMPACTED WITH METAL OR WOOD TAMPS. THE FINISH GRADE SHALL BE MADE SMOOTHWITH THE TOP OF THE CONCRETE SURFACE. ALL EXCESS MATERIAL AND DEBRIS SHALL BE REMOVED FROM THE SITE.

3.11 SIDEWALKS SHALL HAVE A OYSTER TABBY FINISH UTILIZING CRUSHED OYSTER SHELLS PER THE PRODUCTS DESCRIPTIONGABOVE AND THE DETAILS PROVIDED IN THESE CONTRACT DOCUMENTS.
