Each Developer may choose to construct new streets within a proposed subdivision of either flexible pavement (bituminous pavement) or rigid pavement (Portland Cement Concrete). If selecting rigid pavement, all streets and alleys shall be constructed, solely at the expense of the Subdivider/Developer, in conformance with the requirements set forth in Table 34-34, with the provisions outlined herein, and with the Standard Specification Plan Sheets.
(A) Should the Village Engineer or Administrator of this Code, determine that the Village's minimum pavement standards are not adequate for a given condition, including, traffic volume, size of loads, subgrade support, or drainage, a revised pavement design shall be proposed by the developer's engineer, subject to all provisions and procedures of the current pavement design which remain applicable, and subject to the review of the Village Engineer or Administrator.
(B) Since it is the intent of this ordinance to assure that the materials, equipment, and methods of construction utilized in the construction of Portland Cement Concrete Pavements are adequate to provide a durable, safe, smooth- riding pavement that will afford a useful life of at least twenty (20) years, the work, materials, procedures, and testing of said pavement shall conform with Section 420 of the IDOT Standard Specifications.
(C) Concrete Admixtures. Concrete admixtures shall conform to Section 1021 - Concrete Admixtures of the IDOT Standard Specifications, provided however, that chloride-based accelerators shall not exceed 0.3% by mass.
(D) Concrete Haul Time. The maximum haul time for concrete transported in truck mixers or truck agitators shall be in accordance with the following:
Concrete Temperature at Point of Discharge | Maximum Haul Time |
50-64°F | 1 hour, 30 minutes |
65-90°F | 1 hour (without retarder) |
65-90°F | 1 hour, 30 minutes (with retarder) |
(E) Portland Cement Specifications. Portland cement concrete shall be Class PV as specified in Section 1020 - Portland Cement Concrete of the IDOT Standard Specifications. Specific mix design criteria are listed in Table 34-33 below.
TABLE 34-33 PORTLAND CEMENT CONCRETE SPECIFICATIONS |
TABLE 34-33 PORTLAND CEMENT CONCRETE SPECIFICATIONS | |
All Street Classifications | |
Mix Design: | Type III, Cement |
Minimum Compressive Strength: | 4500 psi |
Minimum Flexural Strength: | 650 psi |
Minimum Flexural Strength: | CA-5 & CA-7 |
Or | CA-5 & CA-11 |
Or | CA-7 Or CA-11 |
Or | CA-14 |
* Slump in inches: | ¾” to 1½” |
Air Content: | 5 - 8% |
Mix Design: | 6 Bag |
* A slump above the maximum specified may be used with the Village Engineer’s approval, up to a maximum of three (3) inches provided the water/cement ratio does not exceed 0.42. | |
(F) Pavement Reinforcement. For those street classifications in Table 34-34 for which Standard Reinforcement: Wire Mesh is required, the Subdivider/ Developer shall use welded wire fabric conforming to AASHTO M 55.
(1) The wire fabric shall be six (6) inches by twelve (12) inches with W4 wire transversely and W6.5 fabric longitudinally.
(2) The fabric shall be lapped twelve (12) inches on the transverse laps and six (6) inches on the longitudinal laps.
(3) Reinforcement shall be placed on the subgrade and supported by proper chairs and spacers prior to paving
(G) Membrane Curing Compound. After the concrete has been finished and immediately after the water sheen has disappeared from the surface of the concrete, the surface shall be sealed with membrane curing compound as approved by the Illinois Department of Transportation.
(1) Under no circumstances shall polyethylene sheeting be placed on the pavement prior to initial set that would cause marking on the pavement surface.
(H) Load Transfer Devices. Dowel bars shall be smooth, plain, round bars conforming to the requirements of AASHTO M-227 grades seventy (70) through eighty (80).
(1) Tie bars (deformed) shall conform to the requirements of AASHTO M-31 grade forty (40).
(I) Joint Sealer. Joint filling compound shall be rubberized asphalt conforming to the requirements of AASHTO M-173.
(J) Underlayment. When required, underlayment shall be of one-fourth (¼) inch thick fabric such as "bidmin", "Petromat", or equal.
