Because the sample is prepared in a manner as it would be applied in the field, the test specimens may be considered representative of the application of a specified surfacing. Such methods include application by squeegees, rollers, trowels, notched trowels, and gage rakes.
These systems vary in several ways, including the number of layers or application steps, the surface finish, and variation in composition.
The results obtained in carrying out this practice should serve as a guide in comparing similarly applied surfacings. No attempt has been made to incorporate into this practice all of the various factors that may affect the performance of such applications when subjected to actual service.
