ASTM D5710/D5710M-22 PDF Download

The standard specification ASTM D5710/D5710M-22 covers Trinidad lake modified asphalt, which is used in the construction of pavements. The asphalt should be blended and homogeneous, as determined by appropriate sampling and testing methods. Several properties of the asphalt, such as penetration, flash point, thin-film oven, solubility in trichloroethylene, and ductility, need to meet specific requirements set in the specification.

In addition to these properties, the standard also covers testing for inorganic material (ash), quantitative extraction of bitumen from bituminous paving mixtures, recovery of asphalt from solution by the Abson method, and kinematic viscosity. All of these tests and measurements ensure that the Trinidad lake modified asphalt meets the necessary criteria for use in pavement construction.

The scope of the specification includes various penetration grades of the asphalt, which range from 40-55 to 120-150. These grades indicate the resistance of the asphalt to penetration and are an important factor in determining the suitability of the material for different pavement applications.
