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.
