For any work proposed or conditions that may arise for which specific standards are not provided below, the INDOT Standard Specifications, 2018, as they may be amended, shall apply.
(A) Rigid base pavements. Concrete on earth, asphalt on concrete base, asphalt on brick base, and brick on earth shall comply with the following standards.
(1) Minimum opening. All excavated openings shall be a minimum of four feet as measured in any direction.
(2) Saw cut. All pavement cuts shall be saw cut in a straight and true manner, and shall be made at right angles or parallel to the pavement centerline. Cuts shall be made to the depth of the existing pavement section. Pavements less than five years old shall be cut only in emergencies and only with the approval of the Town Council.
(3) Sizing of pavement replacement.
(a) For asphalt pavement on concrete or brick base, the existing pavement shall be milled one and one-half inches to a minimum distance of five feet in either direction (measured parallel to the road centerline) from the edge of the excavated opening or saw cut, with a width equaling that to the road centerline.
(b) For utility cuts that cross the road centerline, the existing asphalt pavement, on concrete or brick base, shall be milled one and one-half inches to a minimum distance of five feet in either direction (measured parallel to the road centerline) from the edge of the excavated opening, with a width equaling that to the entire road.
(c) For concrete on earth or brick on earth pavement, the existing pavement shall be removed to a necessary size, not less than the minimum excavated opening of four feet.
(d) If a cut line is less than five feet from an existing expansion or weakened plane joint, concrete or asphalt shall be removed to that joint.
(4) Backfill.
(a) For asphalt pavements on concrete or brick base, all trenches, holes, and pits shall be filled to a depth 11 inches from the top of the existing pavement section. Backfill material shall be a flowable fill mixture in accordance with INDOT Standard Specifications § 213.
(b) For concrete on earth, all trenches, holes, and pits shall be filled with a flowable fill mixture, in accordance with INDOT Standard Specifications § 213, to a depth of six inches from the top of the existing pavement section.
(c) For brick on earth pavements, all trenches, holes, and pits shall be filled with a flowable fill mixture, in accordance with INDOT Standard Specifications § 213, to a minimum depth of six inches from the bottom of the existing pavement section. This six inches is filled with sand to the bottom of the existing pavement section.
(5) Pavement replacement.
(a) For asphalt pavement on concrete or brick base, the work of final restoration of the paving surface shall be performed by the permittee by placing ten inches of HMA base and/or binder to fill the excavated opening, and one and one-half inches of HMA surface to match existing grade. A tack coat shall be applied between pavement surfaces and new asphalt.
(b) For concrete on earth pavement, the work of final restoration of the paving surface shall be performed by the permittee by placing six inches of 4,000 psi concrete to match existing grade. All concrete replacement, including base material, shall be high-early strength concrete and shall be returned to traffic as soon as its strength reaches 2,800 psi (three days).
(B) Flexible base pavements. Asphalt with stone base shall comply with the following standards.
(1) Saw cut. All pavement cuts shall be saw cut in a straight and true manner and shall be made at right angles or parallel with the pavement centerline. Cuts shall be made to the depth of the existing pavement section. Pavements less than five years old shall be cut in emergencies only and/or with the approval of the Town Council.
(2) Backfill. All trenches, holes, and pits shall be filled to a depth 11
½
inches from the top of the existing pavement section. Such material is limited too flowable fill mixture in accordance with INDOT Standard Specifications § 213.
(3) Sizing of pavement replacement.
(a) The existing pavement and base shall be removed to provide a minimum length of the trench, plus one foot on either side (measured parallel to the road centerline), with a width equaling that to the road centerline. An additional length of five feet of surface pavement (on either side of the trench), with a width equaling that to the road centerline, shall be milled to a depth of one and one-half inches.
(b) For utilities that cross the road centerline, the existing pavement and base shall be removed to provide a minimum length of the trench, plus one foot on either side (measured parallel to the road centerline), with a width equaling that of the entire road. An additional length of five feet of surface pavement (on either side of the trench), with a width equaling that to the entire road, shall be milled to a depth of one and one-half inches.
(4) Pavement replacement.
(a) The existing pavement and base within the trench plus the one foot of length, shall be replaced with six inches of flowable fill mixture in accordance with INDOT Standard Specifications § 213, four inches (minimum) of HMA binder, and one and one-half inches of HMA surface. The remaining milled section shall be replaced with one and one-half inches of HMA surface. A tack coat shall be applied between the HMA binder and the HMA surface as well as at the saw cut joints.
(b) Where a cut line is less than five feet from an existing patch and/or existing joint, the asphalt shall be removed to include said patch.
