ASTM D3141/D3141M-15 PDF Download

The ASTM D3141/D3141M-15 standard specifies the properties, sampling, and testing requirements for asphalt used in undersealing Portland cement concrete and overlaid concrete pavements. Undersealing involves pumping hot asphalt under the concrete slabs to provide additional support and prevent cracking or water infiltration.

The asphalt used for undersealing should be homogeneous and free of water. It should meet specific requirements when tested for softening point, flash point, penetration at specified temperatures, ductility, heat loss, and solubility of bitumen in trichloroethylene. These tests ensure that the asphalt is of suitable quality and will perform effectively in undersealing applications.

The purpose of this standard is to provide a standardized specification for asphalt undersealing materials, facilitating consistency and quality control in pavement construction and maintenance. Compliance with this standard helps ensure that the asphalt used in undersealing applications meets the necessary performance criteria and contributes to the long-term durability and structural integrity of the concrete pavement.
