ASTM D5078/D5078M-11 (R2021) PDF Download

The ASTM D5078/D5078M-11 (R2021) standard is a specification for hot-applied crack filler that is intended for use in filling cracks in asphalt concrete and portland cement concrete pavements. The purpose of this standard is to provide guidelines for the selection and use of a suitable compound that will effectively fill cracks in concrete surfaces and also resist softening and pickup by vehicle tires at ambient summer temperatures.

The crack filler must meet certain requirements in order to be compliant with this standard. These requirements include specifications for safe heating temperature, softening point, cone penetration, resilience, and asphalt compatibility. The safe heating temperature ensures that the filler can be properly heated without causing any safety hazards. The softening point determines the temperature at which the filler becomes pliable and can effectively fill cracks. The cone penetration measures the consistency of the filler, specifically its ability to penetrate cracks. The resilience refers to the filler's ability to withstand traffic and environmental stresses without deformation or deterioration. Lastly, the asphalt compatibility ensures that the filler can effectively bond with asphalt concrete surfaces.
