§ FPWR-5 Excavation.

General requirements. The excavation and reconstruction of sidewalks, bike-paths, curbs, wheelchair ramps, road pavement, shoulders and other structures in the public way shall be in accordance with standards set forth in these regulations. As a general rule, reconstruction shall be of the same type and design as that existing at the time work was commenced. However, in certain instances, the Director may require the applicant to alter the reconstruction.

Pavement cutting. Pavement will not be disturbed if driving dry boring, coring or jacking methods can be used to accomplish the installation. Extreme care must be taken to protect existing underground utilities. All pavement cutting will be either perpendicular to or parallel to the center line of the roadway or sidewalk and any deviation from this policy must be approved by the Director.

Cutting of bituminous pavement surface with a pneumatic cutter or its equal ahead of excavations is required. Such cutting will be done to confine pavement damage to the limits of the trench.

Sections of cement concrete sidewalks shall be removed to the nearest score line or approved saw cut edge.

Unstable pavement shall be removed over cave-outs and over breaks, and the subgrade shall be treated as the main trench.

Pavement edges shall be trimmed to a vertical face and neatly aligned with the center line of the trench.

Cutouts outside of the trench lines must be normal or aligned parallel and/or perpendicular to the center line of the trench.

Trenches and excavations shall be braced and sheathed when necessary, as required by OSHA specifications.

No work will be permitted to be done under the hardened surface of any newly paved road, except emergency repairs or work that is absolutely unavoidable, for a period of five (5) years. Such work shall be permitted at the discretion of the Director of Public Works.

Trenches. Unless a shorter length is specified by the Director, the length of open trench permissible at any one time shall be limited to no more than three hundred (300) feet. No greater length shall be open for pavement removal, excavation, construction and backfilling without written permission of the Director.

Backfilling.

The trench in the street must be filled and temporarily resurfaced in the same day it is opened unless otherwise directed by the Director or his designee. The trench shall be backfilled to within twelve (12) inches of the top with approved excavated materials. Ten (10) inches of approved gravel shall be placed in the trench and the remaining two (2) inches shall be filled with temporary bituminous surface. Road surface shall be precut to avoid damaging surfaces surrounding the trench.

The backfilled material in the trench must be mechanically tamped in six-inch layers; or if backfill material does not contain too much clay, it may instead be thoroughly puddled unless otherwise directed by the Public Works Department. If the temporary road surface is not placed the first day, then as soon as it is consistent with the permanency of the work or directed by the Public Works Department, the gravel subbase shall be excavated to the required grade in order to place two (2) inches of bituminous surface. The temporary pavement shall be placed and raked to a uniform surface, rolled to the thickness and to grade that will match the existing bituminous road surface.

The applicant shall maintain the temporary surfacing and shall promptly fill with similar material any depressions and holes that may occur so as to keep the surfacing in a safe and satisfactory condition for traffic.

Temporary resurfacing may be either so-called "cold patch" or plant mixed hot-asphalt aggregate, all is produced in accordance with the standard specifications of the Massachusetts Department of Public Works and is to be a minimum of two (2) inches compacted thickness.

A minimum of three (3) months after the temporary resurfacing, unless a shorter period is approved by the Director, the temporary subbase shall be excavated to the required grade in order to place the bituminous concrete surface.

Restoration of permanent paving.

All permanent paving shall be done in accordance with the specifications of the Department of Public Works of the Town of Falmouth by and at the expense of the applicant.

The applicant shall remove and acceptably dispose of all excavated material before proceeding with the remainder of the work and shall thoroughly compact the surface of the subbase. Any broken or irregular edges of existing pavements shall be cut away in a straight line as directed leaving a sound vertical face at least six (6) inches back from the edge of the existing pavement.

The bituminous concrete base and top shall be laid and rolled in two (2) courses. The binder (base course) shall be two (2)[1] inches in depth and the top course shall be one and one-half (1 1/2) inches in depth. The minimum total thickness of both courses, measured after rolling, shall be three and one-half (3 1/2) inches. The base course of a permanent pavement shall be placed and carefully raked to a minimum surface and thoroughly rolled to the required thickness. Before placing the base course of the permanent pavement, the edge of the original bituminous surfacing shall receive an application of approved asphalt emulsion so that the new pavement material may be properly bonded to the old. The top course of the permanent paving shall be placed to a grade that will match the existing bituminous surface after rolling.

[1]

NOTE: Base shall not be less than existing roadway base course and not less than two (2) inches.

The permanent paving shall not overlap the existing pavement and will not have to be applied with a mechanical spreader unless otherwise directed.

The applicant shall furnish, place, grade and compact bituminous concrete pavement of Class I Type I-I as shown and specified in the latest Massachusetts State Department of Public Works Standard Specifications for Highway and Bridges.

Under certain circumstances where trenches are considered extensive it may be required, upon completion of patching trenches, to overlay the affected area for the full width of roadway and at least thirty (30) feet beyond the affected area with one (1) inch of dense graded bituminous concrete.

All lawn surfaces over the trench shall be replaced with sod or loam and reseeded to grade. All sidewalks dug through shall be carefully patched after backfilling. A bituminous concrete sidewalk shall be squared off and patched with the same material and rolled so as to provide a continuous smooth surface. Cement concrete sidewalks shall be repaired by making a new concrete block or blocks through which the trench passes. Preformed expansion joints, when deemed necessary, will be installed against buildings, walls, steps, foundations or existing concrete blocks. The new cement concrete square shall be made by air-entrained Class "A" (3,500-pound) mix or better and be matched in color with the remaining sidewalk as nearly as possible. All concrete must be cured by covering with material in accordance with the best known concrete curing procedures. All walks shall be laid over a minimum of twelve (12) inches of well compacted gravel. Cement concrete shall be treated with silicone or linseed oil sealer for salt damage prevention. The applicant shall be responsible for repairing any damage to public utilities (water, sewer, gas, electric, telephone, etc.) or to town trees, shrubs, poles or signs which may be disturbed or damaged during the course of the work or on account thereof. The applicant shall be responsible for the maintenance of the street opening excavation trench for one (1) year after the date of completing the installation except where such maintenance is made necessary by the act or neglect of another. Exceptions to the permanent paving requirement of the Department of Public Works of the Town of Falmouth may be made only for state or federal government agencies.

(8)

All restoration of cement patch paving areas shall be done at the expense of the applicant and must meet with specification of the Department of Public Works.

(9)

In instances when open cut is permitted, provisions for patching will require, wherever approved by the Director, that six-inch reinforced or precast concrete slab be laid over the backfilled trench extending one (1) foot beyond either side of the edge of surface and allowing for a three-inch bituminous concrete Type I-I surface.

(10)

When approved, the concrete slab may be cast-in-place conforming to Massachusetts Standard Specifications for Class "F" Cement Concrete and, additionally, shall be high-early strength. The slab shall have steel reinforcing for tensile strength placed in accordance with good engineering practices. The applicant must place temporary heavy duty plating adequate to carry heavy traffic over the trench area until the concrete is sufficiently cured.

(11)

Consideration may under certain limited conditions be given to the elimination of the concrete patch, allowing underground utility installations to be made where the applicant agrees to replace foundation and base material in kind, and to maintain satisfactorily a permanent (plant mixed hot asphalt) bituminous concrete Type I-I patch for a period of one (1) year except at which time the original permanent patch with approved material. In this case a specific bond may be required to insure the continued maintenance of the permanent (temporary) patch and the construction of the permanent patch at the end of the one-year period.

Restoration of pavement markings. All permanent pavement markings (crosswalks, traffic center lines, etc.) which are obliterated or damaged during construction shall be repainted by or under the direction of the Department of Public Works at the expense of the applicant.

Lawns and plantings. All lawn surfaces which are disturbed shall be replaced with sod or six (6) inches of screened loam, limed, fertilized and reseeded with a good quality lawn seed. Likewise any areas containing plantings shall be restored to their original condition with the same or similar plantings. Special care shall be taken to insure the areas are re-landscaped to meet the conditions which existed before the excavation.

Shoulders. Shoulders which are disturbed shall be reconstructed to previously existing grade and, regardless of its existing condition, shall be loamed with six (6) inches of loam, limed, fertilized and seeded with a good quality lawn seed.

Sidewalks and bike-paths.

Full width pavement restoration shall be required for all sidewalk and bike-path excavations.

Bituminous concrete sidewalks and bike-paths shall be repaired using the specifications required for roadway backfilling and patching, with the exception that the existing base may be reused if the material is suitable in the opinion of the Director or his designee. The thickness of the bituminous material will be two (2) inches in one (1) course.

Cement concrete sidewalks shall be repaired by making a new concrete block or blocks through which the trench passes. Preformed expansion joints, when deemed necessary, will be installed against buildings, walls, steps, foundations or existing concrete blocks. Specifications and details are available from the Engineering Department.

Brick sidewalks shall be repaired in accordance with specifications and details available from the Engineering Department.

These regulations will apply to sidewalks and bike-paths maintained by the Town of Falmouth located in the Commonwealth of Massachusetts rights-of-way.

Curbs and berms.

Precast concrete and granite curbs. Concrete or granite curbing which in any way is damaged shall be replaced with granite curbing unless otherwise approved by the Director and shall conform to standards.

Construction. Driveway entrances onto public ways shall be constructed or reconstructed according to the conditions existing in the immediate area and shall have a positive pitch to the street and a minimum of four (4) inches of bituminous concrete on six (6) inches of three-fourths-inch dense grade material. Driveway entrances in areas which have concrete sidewalks shall have a minimum thickness of eight (8) inches of portland cement concrete with six-by-six No. 8 wire reinforcing on six (6) inches of three-fourths-inch dense grade material. All openings shall be bituminous concrete or cement concrete extending for a minimum of five (5) feet back from the existing roadway pavement. If openings are to be constructed through existing sidewalks, the requirements as stated above will extend through the full width of sidewalk or for five (5) feet, whichever is greater. In addition, all sidewalk construction will comply with the standards as set forth in the "Rules and Regulations of the Architectural Barriers Board" of the Commonwealth of Massachusetts. Driveways shall not have a greater width than thirty (30) feet (not including splays).

Location. Driveways shall not be located on small radius curves and shall be positioned as to provide maximum sight distance and safety. Tree removal will be permitted only when an adequate driveway entrance cannot be established in a location where such removal could not be avoided. Removal must be approved by the Town Tree Warden.

Abandoned entrances. Abandoned entrances shall be reconstructed to match the existing surrounding area. Entrances to be abandoned will be so noted on the plans submitted with the application.

In particular, the applicant shall protect drainage structures from siltation by whatever means required, including but not limited to the piling of excavated material away from drainage structures and the installation of hay bales or filtered fabric fences. In the event that drainage facilities do become damaged by siltation, the applicant will be required to clean or replace damaged drainage structures as determined by the Department of Public Works, at the expense of the applicant.

Infrared heater method.

Repairing of bituminous concrete roads and sidewalks by the infrared heater method shall be as follows:

Area to be repaired shall be swept clean to remove all loose and foreign material.

An approved infrared heater shall be placed over the area to be repaired for several minutes until a depth of two (2) inches of the existing pavement has been softened. Care must be taken to avoid oxidation of the pavement by improper heating techniques. If this condition occurs, the unsuitable material must be discarded, and the new material added.

The softened area shall be scarified and raked to a workable condition.

(d)

Surplus material must be removed, or Class I, bituminous concrete top added as required to bring the heated area to desired grade.

(e)

After paving mixture has been properly blended, spread and raked to grade, compaction shall be obtained by use of a power roller of sufficient weight to establish a uniform density comparable to that of adjacent surfaces within the work area. Finished patch shall be level with no depression holding water on any of its surface.

(f)

Edges of the rolled area shall be sealed with suitable asphalt emulsion and sand spread over the entire newly patched area.

(g)

Work area shall then be swept of all old and excess materials, and left in a neat condition.
