ASTM D994/D994M-11 (R2016) PDF Download

The ASTM D994/D994M-11 (R2016) standard is a specification for preformed expansion joint filler for concrete, specifically the bituminous type. This type of expansion joint filler is used in concrete construction to provide flexibility and accommodate movements within the structure. The filler is made up of a bituminous mastic composition, which can be either asphalt or tar, that is enclosed between two layers of either bituminous impregnated felt or glass-fiber felt. The mastic composition consists of mineral fillers, reinforcing fibers, and may also include thin strips of reinforcing sheet material.

The standard outlines various test methods that need to be performed to determine different properties of the bituminous preformed expansion joint filler. These properties include distortion at 52°C, brittleness, water absorption, and compression. By conducting these tests, the quality and performance of the filler can be assessed, ensuring its suitability for use in concrete construction projects.

It is worth noting that attention is drawn to related ASTM specifications, specifically ASTM D1751 and D1752, which may have relevance or complementary requirements to consider in conjunction with this standard. These specifications cover other aspects of asphalt and tar used in various construction applications.
