(A) Pavement structure. All streets shall be paved across the entire surface width specified herein. The structural composition of the pavement shall conform to the minimum requirements set forth herein unless higher standards are recommended by staff based upon recognized engineering standards. Design requirements for rigid and bituminous concrete pavements are set forth hereinafter.
(B) Rigid pavement. Rigid pavement shall be constructed to the thicknesses shown herein and in strict accordance with the applicable provisions of the Illinois Standard Specifications for Road and Bridge Construction.
(1) All joints to be sealed after joints are cleaned.
(2) Contraction joints are to be provided at the spacings shown herein for each of the various alternates. These transverse joints are to be sawed joints that are one-eighth inches to one-fourth inches wide with a depth equal to one-fourth of the pavement thickness. Sawed construction joints are to be cut at least within 24 hours of placement of the concrete. In all cases, joints must be cut before the concrete cracks or the entire panel shall be removed and replaced at the contractor's expense. Joints requiring reinforcement shall be reinforced with 30-inch #4 deformed tie bars on 12-inch centers.
(3) (a) Expansion joints shall be located per Illinois Department of Transportation standards and as located by the developer's design engineer. Expansion Joints are to be dowelled. Dowel sizes and spacing shall comply with the following requirements:
Pavement Thickness | Min. Dowel Diameter | Min. Dowel Length | Min. Dowel Spacing
|
6" | 3/4" | 14" | 12" |
8" | 1" | 14" | 12" |
(b) The dowel units are to be smooth, plain round bars placed at mid-height of the pavement with an expansion cap on one end. The bars, or assemblies, shall be placed so that the bars are parallel to the centerline and to the pavement surface and shall be treated to prevent bonding of the concrete.
(4) (a) Longitudinal joints shall be constructed no closer than eight feet and no farther apart than 14 feet. The longitudinal joints may be either "construction" joints or "sawed" joints. In either case, there shall be transverse #4 deformed tie bars, 30 inches long, spaced at 30-inch centers along all longitudinal joints. This includes the joint between the pavement and curb/gutter if the curb/gutter is not constructed integral with the pavement.
(b) Sawed longitudinal joints shall be sawed within 24 hours of concrete placement and prior to any traffic or vehicles traveling on the surface or random cracks occurring in pavement. If a random crack occurs, the entire panel or panels will be removed and replaced. All joints to be sealed after the pavement is cleaned.
(5) Transverse construction joints shall be constructed at the end of each day's run or at locations where a "cold" joint will occur due to a delay or interruption in placement operations. All transverse construction joints shall be "tied" with #4 deformed bars, 35 inches long, spaced at 12-inch centers. Construction joints must be at least five feet from any other joint including another transverse construction joint. All joints to be sealed after joint is cleaned.
(6) (a) Pavement reinforcement shall be used in all rigid pavements designated as S.R.P.C.C. herein. Reinforcement shall be welded wire fabric (6" by 12") with W 4 wire transversely and W 5.5 wire longitudinally weighing approximately 54 pounds per 100 square feet. The fabric shall be lapped 12 inches on transverse laps and six inches on longitudinal laps. Reinforcement shall be placed on the sub-grade and supported by proper chairs and spacers, prior to paving, at the heights specified below:
Pavement Thickness | Depth Below Pavement Surface |
6" | 2" min, 3" max |
8" | 3" min, 4" max |
(b) Should a question arise whether the minimal standards are adequate for a given condition (i.e. traffic volume, size of loads, sub-grade support, drainage and the like), the required pavement design shall be determined by the subdivider's engineer on the basis of current pavement design procedures subject to the review of the village staff.
(7) Every concrete street, and curb and gutter constructed in the village shall have a compressive strength of 4,000 PSI at 28 days. The subdivider or developer shall provide to the village staff at no expense to the village, concrete tests verifying compressive strength. The number of the tests shall be determined by the village staff. The village staff shall also have the right to request other tests, including air entrainment and slump tests, as it deems necessary.
(C) Bituminous concrete pavement. Bituminous concrete pavement (asphalt pavement) shall be constructed to the thicknesses shown within § 151.272 and in strict accordance with the applicable provisions of the Illinois Standard Specifications for Road and Bridge Construction. All mix designs shall be approved by the City Engineer. The surface course on all original roadway construction and pavement widenings shall be comprised of only virgin materials.
(1) Should a question arise whether the minimal standards are adequate for a given condition (i.e. traffic volume, size of loads, sub-grade support, drainage and the like), the required pavement design shall be determined by the subdivider's engineer on the basis of current pavement design procedures subject to the review of the village staff.
(2) Every asphalt street shall be tested in accordance with ASTM and AASHTO standards by a testing firm that meets ASTM requirement E-329. Plant inspections are required with a minimum of 100 per tons per day completed during construction by the developer's/owner's testing firm. In-place density/thickness ASTM D1159, AASHTO T209, AASHTO T245 shall be completed by nuclear testing device at a minimum of every 200 feet per lane per lift, and one per cul-de-sac during construction by the developer's/owner's testing firm. Density/thickness ASTM D2726-96, AASHTO T164, ASTM Dl856-95, AASHTO T170, ASTM D2041-95 shall be completed by core testing. Two cores minimum per day (one core full testing with second core standby) shall be taken by the developer's/owner's testing firm. All results from material testing shall be submitted to the Village of Shiloh for review.
