(A) General. This item shall consist of the construction of bituminous or concrete bike paths in accordance with these specifications and the dimensions shown on the plans.
(B) Materials.
(1) Materials shall meet the requirements specified in the following subsections:
(a) Joint fillers; § 13-10-10(B)(5) of this chapter;
(b) Bed course material; § 13-10-10(A) of this chapter;
(c) Concrete for bike paths; § 13-10-10(B) of this chapter; and
(d) Bituminous material for sidewalks; § 13-10-10(C) of this chapter.
(2) Concrete and bituminous mixes will be subject to inspection and tests as required to assure compliance with quality requirements.
(C) Construction methods; concrete bike paths.
(1) Excavation. Excavation shall be made to the required depth and to a width that will permit the installation and bracing of the forms. The foundation shall be shaped and compacted to a firm, even surface conforming to the section shown in Figure 3.617*. When the Engineer determines that material is unsuitable, the material shall be removed and replaced in accordance with § 13-10-11(E) of this chapter.
(2) Forms. Forms shall be of wood, metal or other suitable material, and shall extend for the full depth of the concrete. All forms shall be straight, free from warp and of sufficient strength to resist the pressure of the concrete without springing. Bracing and staking of the forms shall be such that the forms remain in both horizontal and vertical alignment until their removal. A satisfactory slip form method may be used.
(3) Placing concrete. The foundation shall be thoroughly moistened immediately prior to the placing of the concrete. The proportioning, mixing and placing of the concrete shall be in accordance with the requirements specified in § 13-10-10 of this chapter.
(4) Finishing. The surface shall be floated with a wooden or magnesium float and given a transverse broom finish. No plastering of the surface will be permitted.
(5) Joints.
(a) Expansion joints and intervals shall be of the dimensions specified, and shall be filled with the type of premolded expansion joint filler noted. The bike path shall be divided into sections by dummy joints formed by a jointing tool or other acceptable means as directed. These dummy joints shall extend into the concrete for at least one-third of the depth and shall be approximately one-fourth inch wide. Dummy joints shall be spaced at intervals approximately equal to the width of the bike path.
(b) Construction joints shall be formed around all appurtenances such as manholes, utility poles and the like, extending into and through the sidewalk. Premolded expansion joint filler one-fourth inch thick shall be installed in these joints. Expansion joint filler of the thickness indicated shall be installed between concrete sidewalks and any fixed structure such as a building or bridge. This expansion joint material shall extend for the full depth of the path.
(6) Curing.
(a) Immediately upon completion of the finishing, bike paths shall be moistened and kept moist for two days, or sidewalks, shall be cured by the use of membrane forming curing compound. The method and details of curing shall be subject to the approval of the Engineer.
(b) During the curing period all traffic, both pedestrian and vehicular, will be excluded. Vehicular traffic will be excluded for such additional time as the Engineer may direct.
(D) Bituminous bike paths.
(1) Excavation and forms. Excavation and forms shall meet the requirements of subsection (C) of this section.
(2) Bed course. Bed course material shall be placed in layers not exceeding four inches in depth and each layer shall be thoroughly compacted.
(3) Placing bituminous bike path material.
(a) Bituminous bike path material shall be placed on the compacted bed course in one or more courses as indicated so as to give the required depth when rolled.
(b) Compaction shall be accomplished by means of a hand operated or power roller of a type and weight acceptable to the engineer. In areas inaccessible to the roller, hand tamping will be permitted.
(c) Bituminous bike paths shall be uniformly compacted.
