Chapter 15.55
RESTORATION OF SURFACE IMPROVEMENTS
Sections:
15.55.040 Cold weather patching.
15.55.010 General.
The contractor shall be responsible for the protection and the restoration or replacement of any improvements existing on public or private property at the start of work or placed there during the progress of the work. All work shall comply with APWA standards unless otherwise stated in this section.
Existing improvements shall include but are not limited to permanent surfacing, curbs, ditches, driveways, culverts, fences, walls and landscaping. All improvements including landscaping shall be reconstructed to equal or better, in all respects, in a timely manner. The contractor shall be responsible for maintaining a road surface suitable for travel by the public. He/she shall be responsible for all dust and mud control and all claims and damages resulting from his/her failure to maintain the construction area.
All road cuts shall be repaired within two working days. All asphalt to be removed must be sawcut in a smooth straight line. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 11.010)].
15.55.020 Gravel surface.
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. All trenching backfill shall conform to the backfill requirements in EMMC 15.30.040.
B. The gravel shall be placed deep enough to provide a minimum of six inches of material.
C. 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.
D. Material for use on gravel surfaces shall be obtained from sound, tough, durable gravel or rock meeting AASHTO T27 requirements. The following requirements for grading shall be met:
|
Passing 1-inch sieve |
100% |
|
Passing 3/4-inch sieve |
85% – 100% |
|
Passing No. 4 sieve |
45% – 65% |
|
Passing No. 10 sieve |
10% – 30% |
|
Passing No. 200 sieve |
5% – 10% |
[Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 11.020)].
15.55.030 Bituminous surface.
Where trenches are excavated through bituminous surfaced 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 EMMC 15.55.020 after the required backfill and compaction of the trench has been accomplished.
B. The trench shall be backfilled in accordance with EMMC 15.30.040.
C. The area over trenches to be resurfaced shall be graded and rolled with a roller weighing not less than 12 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 or spongy material shall be removed and the space filled with gravel and rolled and tamped thoroughly in layers not exceeding six inches in thickness. The edges of trenches that 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 shall cut the existing paving to clean, straight lines as nearly parallel to the centerline of the trench as practicable and 24 inches wider on each side of the trench than initial excavation. Said straight lines have no deviations from such lines, except as specifically permitted by the engineer.
E. Existing bituminous paving shall be cut back a minimum of 24 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 20 inches of undisturbed soil. See also APWA Standard Detail 255, Asphalt Concrete T Patch.
F. Within two working days and weather permitting, the bituminous surface shall be restored by standard paving practices to a minimum thickness of four inches for local streets and six inches for collector, industrial, and commercial streets to match existing pavement height.
G. Pavement restoration shall include priming of pavement edges and subbase with an asphalt tack coat and placing and rolling plant mix bituminous material to the level of the adjacent pavement surfaces.
H. All pavement restoration shall conform to Chapter 15.60 EMMC. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 11.030)].
15.55.040 Cold weather patching.
Trenches cut during winter months or when asphalt plants are not operating shall be patched the same day of the cut with a good quality cold mix and maintained until asphalt plants open. When asphalt plants open, the cold patch shall be removed and a new patch of hot mix asphalt shall be placed within 20 days of plant opening. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 11.040)].
15.55.050 Concrete surfaces.
All concrete curbs, gutters, sidewalks and driveways shall be removed and replaced to the next joint or scoring lines beyond the damaged or broken sections; or, in the event that 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. On all new concrete improvements 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 the APWA Standard Specifications. [Ord. O-09-2024 § 2 (Exh. A); Ord. O-13-2015 § 1 (Exh. A); Ord. O-03-2010 § 1 (Exh. A § 11.050)].
