FIELD: technological processes.
SUBSTANCE: method can be used in field of road-building materials. When estimating cohesion of filling agent with mortar part of asphaltic concrete fixed is stamp-standard from three rigidly connected similar elements with lower part from filler in mortar part of examined asphaltic concrete at specified depth of metal reservoir, connected with bed, by fastening stamp-standard in rod system, moving it with respect to surface of mortar part of examined asphaltic concrete by means of thread connection, connected with rod system. After that, metal reservoir is rotated at 180° with respect to bed. Then, stretching effort is created in contact zone of each element of stamp-standard by application to each of three similar elements of stamp-standard of static rupture loading, said loading is recorded at the moment of breaking off of each of three similar element of stamp-standard, located at angle 120° with respect to each other, from mortar part of examined material, and value of tension in contact zone of each of three similar elements of stamp-standard by value of ratio of loading value to size of area of contact zone between filling agent - lower part of each of three similar elements of stamp-standard - and mortar part of asphaltic concrete.
EFFECT: increased accuracy of experimental estimation of cohesion parameter and reduced labour consumption of method realisation with application of great number of stamp-standards.
