It will be necessary to follow the procedures as outlined below and all applicable Illinois Department of Transportation standards when opening, backfilling and constructing on village rights-of-way. In case of conflict, this notice shall take precedence. All article and section references are to the Illinois Department of Transportation Standard Specifications for Road and Bridge Construction, adopted 1-1-2012, herein referred to as IDOT standards.
(A) Compaction of backfill material. Each excavation in or on a public street, driving surface or sidewalk shall be backfilled per Section 208 of the IDOT Standards, except as modified herein:
(1) Article 208.02 “Materials” shall be changed to require the use of coarse aggregate as specified in Section 1004 of the IDOT Standards, and that the coarse aggregate gradation shall be CA6. Fine aggregate will not be allowed.
(2) Trench backfill material shall be compacted in accordance with Method 1, as specified in Article 542.04 of the IDOT Standards.
(3) Whenever the village staff have reasonable cause to believe that backfilling for any excavation is not being done with acceptable materials or is not being adequately compacted, village staff will require tests to determine whether or not the backfill material/compaction technique meets the minimum requirements prescribed. All expense for such tests shall be borne by the permittee.
(B) Twelve-inch bench on all excavations in public streets, driving surfaces and sidewalks required. A one-foot ledge of undisturbed earth on all four sides of the excavation shall be left to support the pavement patch. The one-foot distance shall be measured from the edge of the subgrade which is disturbed by the vertical excavation.
(C) Patches in pavement.
(1) Existing un-reinforced pavement must be first scored with a saw to a depth of three inches. All others to be determined by pavement type per Article 442.01 class A, B or C.
(2) Patches in concrete pavements shall be placed equal to the thickness of the adjacent pavement but in no case shall a concrete patch be less than eight inches deep. Saw kerfs in concrete pavement to be filled and sealed with either hot poured joint sealer or self leveling polyurethane sealer, limestone color. Edges of all concrete pavement patches and any construction joints within the patch shall be tooled or sawn to provide an adequate reservoir for joint sealer. Joints to be sealed in the same manner as saw kerfs. The patching technique is to be determined by existing pavement type per Article 442.01 class A, B or C. All patch classes to be placed per § 442, pavement patching.
(3) Where excavations are made in concrete pavements the pavement area removed will also be controlled by the proximity of existing joints. If the pavement area to be removed is one foot or less from a joint, the pavement shall be removed to the existing joint. In no case, however, shall the one-foot distance required by division (B) herein be disregarded. If, in the removal of pavement, an expansion joint is damaged, or removed, it shall be replaced with pre-molded asphaltic expansion joint one inch thick. Joints are to be sealed per Article 420.12.
(4) Patches in oil and chip surface treatment shall be Class A-3 per § 403.
(5) Patches in areas previously overlain with asphalt or asphalt streets shall be replaced as follows:
(a) Asphalt overlays shall have an asphalt surface equal to the thickness of the existing blacktop surface placed on a concrete base course. The concrete base course shall be the thickness of the original concrete, but not less than eight inches. All asphalt work shall be per § 406.
(b) Asphalt streets shall match the existing, but in no case shall asphalt thickness be less than six inches, with four inches being base course and two inches surface course. The base course is to be per § 355 and the surface course to be per § 406.
(6) Written notification shall be given to village staff 24 hours prior to pouring or placing any permanent street patches.
(7) Temporary patches for the convenience of traffic movement must be placed. They shall be made with a good quality of bituminous patching material properly placed and thoroughly rolled, or tamped to optimum compaction. The individual or company holding the excavation permit shall be responsible to insure that the temporary patch is properly maintained. Temporary patching may not be left in place longer than 60 days. After removal of temporary patch and prior to placing permanent repair, rock subbase surface shall be compacted.
(8) Any striping that is removed with the patch shall be replaced in kind. Pavement striping shall be per § 780.
(D) Sidewalk. Sidewalk shall be sawn full depth at nearest joint. Sidewalk is to be constructed per § 424.
(1) Where sidewalks are perpendicular to curb, or parallel and restricted on side opposite curb, a one-inch preformed expansion joint filler shall be inserted by curb before sidewalk replacement. Otherwise a one-half-inch expansion joint will be required between sidewalk and curb. Expansion joint filler shall be equal to “Homex-Plus” with bond breaker.
(2) After removal of top filler, expansion joint shall be sealed with polyurethane sealant, limestone color, equal to “Sonolastic” SL1 or SL2.
(3) Where street signs occur in sidewalk to be replaced, a four-inch diameter plastic pipe shall be placed centered on sign, full depth of sidewalk. Void around post shall be filled with cold patch and compacted.
(E) Curb or curb and gutter. Curbs to be cut full width a minimum depth of four inches and carefully removed as to insure a vertical edge. Curb or curb and gutter to be constructed per § 606.
(1) Where a patch occurs at a pavement expansion joint or no existing expansion device is within 50 feet of the patch, a one-inch thick preformed expansion joint filler, cut cross section of the curb or curb and gutter shall be inserted and a one and one-fourth-inch diameter, 18-inch long, smooth coated dowel bar, greased or fitted with end cap providing a minimum of one-inch expansion be installed.
(2) Expansion fillers shall be equal to “Homex-Plus” with bond breaker.
(3) After removal of top filler strips, expansion joints shall be sealed with polyurethane sealer, limestone color equal to “Sonolastic”.
(4) Saw kerfs resulting from cutting operation will be remedied as per this section by sealing with approved sealer.
(5) Requirements of the Illinois Accessibility Code shall be adhered to at all times. If a ramp is built on one corner another shall be built on opposite corner. Ramps shall be constructed per IDOT Standard.
(F) Driveway. Driveways shall be the same as sidewalks except that the driveway shall have #6 reinforcing mesh across the entire breadth and width at driveway and the concrete shall be a minimum of six inches deep for residential and eight inches deep for commercial.
(G) Traffic control.
(1) All excavation areas shall be properly barricaded and lighted for the protection of the general public.
(2) The individual or company holding the excavation permit shall be responsible to insure that traffic control is maintained per applicable IDOT standards.
(H) Clean up. As the excavation work progresses, all streets, sidewalks and yards shall be thoroughly cleaned of all rubbish, excess earth, rock and other debris resulting from the work. All clean up operations at the location of the excavation shall be accomplished at the expense of the permittee and shall be completed to the satisfaction of the village staff. From time to time as needed, and in any event immediately after completion of the work, the permittee shall at his or her own expense clean up and remove all refuse and unused materials of any kind resulting from the work. Failure to do so within 24 hours after having been notified by the village staff, will result in the village staff having the work done and the cost thereof charged to the permittee.
(I) Lawn restoration. At locations where it is necessary to excavate in lawns that are in public right-of-way, the persons making the excavation will complete the restoration in the following manner:
(1) Backfill. Excavation shall be backfilled within 12 inches of final grade as per a compaction of backfill material. The final 12 inches shall be of compacted top soil.
(2) Turf or grass areas. At the request of the village or adjacent property owners, sod of the type and quality that existed prior to excavation will be replaced in kind.
(3) Decorative rock and miscellaneous landscaping material. At the request of the village and the adjacent property owners, decorative rock and other landscaping material of the type and quality that existed prior to excavation, will be replaced.
(4) Trees and shrubs.
