1051.01 Methods of Sampling. Two samples, each 12 in. (300 mm) in length
and full width, will be taken for each 1000 ft (300 m) or fraction thereof. Individual samples will be taken from separate pieces of preformed expansion joint filler selected at random.
1051.02 Methods of Testing. In addition to Article 106.03, preformed
expansion joint fillers will be tested as follows. Extraction of Asphalt. The asphalt will be extracted by means of a Soxhlet extraction apparatus (large), equipped with a glass extraction shell having a round, perforated bottom. A small quantity of glass wool will be placed in the bottom of the extraction shell. Trichloroethylene shall be used as the extracting solvent. A sample weighing approximately 45 g will then be cut into narrow strips and packed in the shell above the glass wool. The residue in the shell, after complete extraction of the bitumen, will be thoroughly dried at a temperature of 215 ± 5 °F (102 ± 3 °C), cooled, weighed, and the percent of bitumen determined by difference. Before extraction, the sample shall be dried for 3 hours in a constant temperature oven at 325 5 °F (163 ± 3 °C).
1051.03 Bituminous Preformed Joint Filler. Bituminous preformed joint filler
shall consist of bitumen, felt, and mineral. Art. 1051.03 Preformed Expansion Joint Fillers The felt shall be roofing felt produced by the felting of vegetable and animal fibers. The felt shall be free from foreign substances, such as leather, rubber, straw, or wood. The mineral shall consist of finely crushed slate, limestone, silica, sand, or similar mineral matter. Roofing scrap may be used in the manufacture of joint filler, provided the quality of felt and mineral are in compliance. The preformed joint filler shall not contain wood in ground form or otherwise, nor coarse fragments of any description, and the presence of straw or cornstalks used as a substitute for felt, or the presence of large particles of slate or other foreign matter will be deemed sufficient cause for rejection. Bituminous preformed joint filler shall further comply with the requirements of AASHTO M 33, except that the percent of soluble material in the mastic portion will be based on an extraction made in trichloroethylene as specified in Article 1051.02.
1051.04 Preformed Fiber Joint Filler. Preformed fiber joint filler shall comply
with the requirements of AASHTO M 213, except that suitable binders other than bituminous will be permitted.
1051.05 Bituminous Preformed Inorganic Fiber Joint Filler. This material
shall consist of a preformed strip made from inorganic fibers securely bound together and uniformly impregnated with a suitable bituminous binder. This strip shall be reinforced with a layer of felt paper on each side and shall be according to the requirements of AASHTO M 213, except that the minimum load to compress the material to 50 percent of its thickness before test is waived.
1051.06 Preformed Cork Joint Filler. Preformed cork joint filler shall comply
with the requirements of AASHTO M 153, Type II.
1051.07 Preformed Self-Expanding Cork Joint Filler. Preformed self-
expanding cork joint filler shall comply with the requirements of AASHTO M 153, Type III.
1051.08 Reserved.
1051.09 Preformed Flexible Foam Expansion Joint Filler. Preformed
flexible foam expansion joint filler shall consist of a synthetic foam of isomeric polymers or other approved material in a small closed cell structure. It shall be chemically inert and have no food value that would attract or support plant or animal life. It shall be odorless and nontoxic, shall remain flexible over a wide range of temperatures, shall be compatible with hot-poured joint sealer meeting the requirements of Article 1050.02, and shall have a melting point of 330 °F (165 °C) minimum.
