Application Summary AI generated

This standard specifies the test method for determining the modifier content in SBS (styrene-butadiene-styrene) modified asphalt used in road engineering. It is applied during quality control and acceptance testing of asphalt mixtures for highway, urban road, and airport pavement construction. The method ensures that the SBS polymer content meets design specifications, directly affecting the pavement's resistance to rutting, cracking, and temperature susceptibility.
