CONCRETE QUALITY: (a) Ready -Mix Concrete must be used which complies with ASTM C -94 and is supplied by a ready -mix source which is inspected yearly by the Illinois Division of Highways, unless otherwise permitted by the Vil- lage Engineer. Delivery tickets shall note the mix designation, time dispatched, date, project and con- tractor, and shall be available for review by the Village Engineer or his representative. - 2 - (b) Concrete mix design shall be owner and contractor's responsibility. Prior to concrete delivery, a report must be submitted from a Commerdial Testing Labora- tory on the proposed mix proportions to the Village Engineer for approval. Prior to concrete delivery, submit laboratory reports on 7 and 28 day strengths of each proposed mix. No concrete will be allowed to be placed until the mix designs have been approved. (c) Concrete mix shall be designed using the following data: i. Minimum compressive strength of 3500 psi at 28 days. ii. Minimum of 6 sacks of cement per cubic yard. iii. Maximum size aggregate of 1 inch. iv. Air entrainment of 6% } 1 %. V, Maximum slump of 4 inches. vi. Maximum water content including moisture in the aggregate of 6 gallons per sack of cement. vii. All concrete shall contain a water- reducing admixture with no reduction in cement content permitted. SECTION 6. SUEGRADE PREPARATION: Where a fill condition exists, all topsoil and unsuit- able material shall be removed. Tamped or rolled until thoroughly compacted before placing granular base. Fill shall be placed in six inch layers to the proper subgrade elevation. Side slopes of fill material shall not exceed one foot vertical to three feet horizontal. Where a cut condition exists, remove all top soil - 3 - and unsuitable material and remove subgrade to the proper eleva- tion allowing sufficient width to accommodate the forms. SECTION 7. GRANULAR BASE: A granular base of 5 inch minimum thickness shall be placed on the prepared subgrade. The base shall extend the full width of the driveway apron. Aggregate gradation shall conform to gradation CA6 of the Illinois Division of Highways standard specifications. SECTION 8. FORMS Side forms shall be of lumber of not less than two inches nominal thickness or steel of equal rigidity. The use of.2 x 4 lumber forms is not permitted. Forms shall be held securely in place by stakes or braces with the top edge true to line and grade. SECTION 9. EXPANSION JOINTS: Expansion joints shall be placed at the junction of the driveway apron and the sidewalk and at the junction of the drive- way apron and the curb. Such expansion joints shall be 2 inch thick premoulded filler strips with the top of the strip placed k inch below the surface of the driveway apron. SECTION 10. PLACING AM FINISHING CONCRETE: The Village shall be notified when the subgrade has been finished, with a minimum of 24 hours notice prior to placing con- crete. No concrete shall be placed until the subgrade has been inspected and approved by the Village. SECTION 11. No concrete shall be placed on ice or frozen subgrade. The subgrade shall be moistened just before the concrete is placed. - 4 - 0 0 The concrete shall be placed in successive batches for the entire width of the slab, struck off from 1/2 to 3/4 inch higher than the finished slab, tamped until all voids are removed and free mortar appears on the surface, thoroughly spaded along the edges, struck off to the true grade, and finished to a true and even surface with floats and trowels. The final troweling shall be done with a steel trowel, leaving a smooth, even surface. After the water sheen has disappeared the surface shall be given a final finish by- brushing with a fine -hair broom. The broom shall be drawn across the driveway apron at right - angles to the edges of the apron with adjacent strokes slightly overlapping, producing a uniform, slightly roughened surface with parallel marks. Con- trol joints shall be constructed so as to divide the driveway apron into sections which are approximately square, and having no side longer than 15 feet. The control joints shall be not less than 1/8 inch nor more than 1/4 inch in width, and shall be edged with an edging tool having a 1/4 inch radius. The minimum depth shall be 1 -1/4 inch. SECTION 12. COLD- WEATHER CONCRETING: After the first seasonal frost the concrete shall be protected from freezing in accordance with "Recommended Practice for Cold - Weather Concreting" (ACI 306). The Contractor and owner shall be responsible for all concrete damaged by low temperatures and any concrete so damaged shall be removed and replaced at their expense. SECTION 13. CURING: methods: Driveway aprons must be cured by one of the following - 5 - • (a) Apply specified curing compound with brush, roller or spray at the rate of one gallon for every 250 square feet of surface. (b) Place burlap on the finished surface, saturate with water and cover with an impermeable covering. (c) Place polethylene sheeting as soon as the concrete has hardened sufficiently to prevent marring of the surface. Wet the surface on the concrete im- mediately before the sheeting is placed. The edges of the sheeting shall be weighted securely with a continuous windrow of earth or any other means satisfactory to the Village to provide an air tight cover. Any of the above curing methods must remain in place for not less than 6 days. SECTION 14. BACKFILL: After the concrete has been cured forms shall be removed and the space near the edges of the driveway shall be backfilled to the required elevation with material approved by the Village. The material shall be compacted then until firm and the surface evenly graded. SECTION 15. DISPOSAL OF SURPLUS MATERIAL: Surplus or waste material resulting from the driveway apron construction operation shall be disposed of by the Contractor or owner. SECTION 16. CONTROL OF MATERIALS: The Contractor or owner shall, at his expense, have a Commercial Testing Laboratory prepare and test samples of delivered concrete.
