SECTION 443. RESERVED SECTION 444. FIBERGLASS FABRIC REPAIR SYSTEM
444.01 Description. This work shall consist of the installation of a fiberglass
fabric repair system prior to placement of a hot-mix asphalt overlay.
444.02 Materials. Materials shall be according to Section 1063.
444.03 Equipment. Equipment shall consist of suitable sweepers, air
compressors, hand brooms, pouring buckets, rubber-edged squeegees, cutting knives, and melting kettles. All hand tools shall be in a clean condition. Melting kettles shall be propane heated and have a temperature controlling thermostat. The Fiberglass Fabric Repair System Art. 444.06 melting kettle shall be clean and free from other bituminous materials which might change the properties of the bituminous adhesive. Since the adhesive is melted and used at higher temperatures than ordinary bituminous paving material, safety procedures concerning fire hazards and skin burns shall be observed. CONSTRUCTION REQUIREMENTS
444.04 General. The existing pavement shall be dry and clean. All base
failures shall be repaired and all cracks, spalls, potholes, or other depressions shall be sealed with an approved crack sealer or primed and filled with binder (hand method) according to Section 406. The repair system shall be applied only when the ambient and pavement temperatures are at least 50 °F (10 °C) and rising. Cleaning shall be accomplished by suitable sweepers, compressed air, or hand brooms. The bituminous adhesive, heated to 375 °F 25 °F (190 °C 15 °C), shall be applied by means of a hand spray bar or a pouring bucket and squeegee. The adhesive shall be squeegeed with sufficient uniformity to prevent streaking or ridging and shall extend a minimum of 1 in. (25 mm) beyond all edges of the fiberglass fabric. The fiberglass fabric shall be immediately placed on the adhesive. The material shall overlap adjacent fabric a minimum of 2 in. (50 mm). The fabric strips shall be free of wrinkles. Additional adhesive shall be squeegeed on top of the fabric and shall extend a minimum of 1 in. (25 mm) beyond all its edges. The application rate for two coats of bituminous adhesive in the system shall be a minimum of 0.70 gal/sq yd (3 L/sq m). When proper thickness is achieved, the weave pattern of reinforcement fabric shall be detectable through the top coat of the adhesive. The repair system may be opened to construction traffic after a 30 minute minimum set time. Any fabric damaged shall be replaced prior to overlaying.
444.05 Method of Measurement. This work will be measured for payment in
place and the area computed in square yards (square meters) of fabric surface. No allowance will be made for the fabric overlaps or the minimum extension of bituminous material beyond the edges of the fabric.
444.06 Basis of Payment. This work will be paid for at the contract unit price
per square yard (square meter) for FIBER GLASS FABRIC REPAIR SYSTEM. Binder (hand-method) will be paid for according to Article 406.14. SECTION 445. RESERVED SECTION 446. RESERVED SECTION 447. RESERVED SECTION 448. RESERVED Art. 449.01Removal and Replacement of Preformed Elastomeric Joint Seals SECTION 449. REMOVAL AND REPLACEMENT OF PREFORMED ELASTOMERIC JOINT SEALS FOR PAVEMENT
449.01 Description. This work shall consist of removing the existing joint seal
and replacing it with a new preformed elastomeric joint seal.
449.02 Materials. Materials shall be according to the following.
Item Article/Section
a.Preformed Elastomeric Joint Seals for Pavement .............................. 1053.01
449.03 Equipment. The machine used to cut the joints shall be an approved
concrete saw. CONSTRUCTION REQUIREMENTS
449.04 Preparation. The existing joint shall be removed and the joint
reshaped to the dimensions shown on the plans. The edges shall be beveled to a smooth surface by either a cutting or grinding device attached to the saw blade following the sawing operation.
449.05 Installation. The joint shall be thoroughly cleaned prior to sealing.
When the joint is free of foreign material and dry, the preformed elastomeric joint seal shall be installed by an approved machine method so that no twisting, rolling, or misalignment with the opposite top edge occurs. The joint shall be sealed across the full width of the entire pavement with one piece of seal material. The seal shall be secured in place with a lubricant-adhesive applied to both sides of the seal or both faces of the concrete. Any adhesive on the top of the seal shall be removed. The seal shall be installed in a compressed condition below the bottom of the beveled edge and within 5/16 in. (8 mm) of the surface of the pavement.
449.06 Tolerances. During installation, the joint seal material will be checked
for stretching and compression by pre-marking the length and width of the seal prior to installation. The stretch and compression tolerances shall be as follows.
a.Stretch. The joint seal material may be stretched five percent or less.
b.Compression. The joint seal material may be compressed two percent or less. Once sealing operations have started, one joint per every twenty-five will be checked for stretch and compression. If an unsatisfactory condition is found, that seal and the seals on either side shall be removed until the condition disappears and the affected joints shall be replaced.
449.07 Method of Measurement. This work will be measured for payment as
follows.
a.Contract Quantities. The requirement for use of contract quantities shall be according to Article 202.07(a).
