    Abstract. A method is proposed for determining the true relative area of adhesive and cohesive joints during tests to establish the adhesion strength of facing tiles with the base under axial tension, according to the current state standard using photogrammetry. An alternative method is presented for determining the adhesion area of tiles to the base based on the creation of photogrammetric models of tiles after testing, followed by the determination of the true relative areas of the free surface of the tile (without traces of adhesive or cohesive bonding), as well as the true relative areas of adhesive and cohesive bonding. Approbation of the developed technique was carried out on samples with different characteristic features of the surface after testing. It has been established that when determining the adhesion strength by the traditional method, the results obtained can be significantly underestimated due to the difference in determining the adhesion area. The general requirements and approaches of the considered new technique using photogrammetry are developed and formulated. The results obtained can be used to refine the existing methods for testing the adhesion strength and adjusting the regulatory documentation.
