Wher existing improvements are disturbed or destroyed, the Contractor shall reconstruct or replace said improvements to an equal or better condition than the existing improvements as determined by the City Engineer.

13-2 ROAD BASE

Where trenches are excavated through gravel surfaced areas such as roads and driveways, etc. The gravel surface shall be restored and maintained as follows:

(a) The gravel shall be placed deep enough to provide a minimum of six inches of gravel.

(b) The gravel shall be placed in the trench at the time it is backfilled. The surface shall be maintained by blading, sprinkling, rolling, adding gravel, etc., to maintain a safe uniform surface satisfactory to the Engineer. Excess material shall be removed from the premises immediately.

(C) Material for use on gravel surfaces shall conform to Section III of these specifications.

13-3 BITUMINOUS SURFACE

Where trenches are excavated through bituminous surface roads, driveways or parking areas, the surface shall be restored and maintained as follows:

(a) A temporary gravel surface shall be placed and maintained as required in Paragraph two above, after the required backfill and compaction of the trench has been accomplished.

(b) The gravel shall be placed to a depth equal to the original but not less than six inches below the pavement and shall be brought flush with the paved surface

(C) The area over trenches to be resurfaced shall be graded and rolled with a roller weighing not less than twelve tons, or with the rear wheels of a five yard truck loaded to capacity, until the subgrade is firm and unyielding. Mud or other soft, spongy material shall be removed and tamped thoroughly in layers not exceeding six inches in thickness. The edges of trenches which are broken down during the making of subgrade shall be removed and trimmed neatly before resurfacing.

(d) Before any permanent resurfacing is placed, the contractor shal.l trim or cut the existing paving to clean, straight lines as nearly parallel to the center line of the trench as practicable. Said straight lines shall be thirty feet minimum length and no deviations from such lines shall be made except as specifically permitted by the Engineer.

(e) Existing bituminous paving shall be cut back minimum of six inches beyond the limits of any excavation or cave-in along the trench so that the edges of the new paving will rest on at least six inches of undisturbed soil.

(f) As soon as practical, weather permitting, the bituminous surface shall be restored by standard paving practices to a thickness equal to the original, but no less than two inches.

(g) Pavement restoration shall include priming of pavement edges and subbase with Type MC-70 bituminous material, and placing and rolling plant mix bituminous material to the level of the adjacent pavement surfaces.

All concrete curbs, gutters, sidewalks, and driveways shall be removed and replaced to the next joint or scoring lines beyond the actually damaged or broken sections; or in the event the joints or scoring lines do not exist or are three or more feet from the removed or damaged section, the damaged portions shall be removed and reconstructed to neat, plane faces. All new concrete shall match, as nearly as possible, the appearance of adjacent concrete improvements. Where necessary, lamp black or other pigments shall be added to the new concrete to obtain the desired results. All concrete work shall conform to the requirements of section V of these specifications.
