METHOD FOR DETERMINATION OF HARDNESS OF ASPHALT-CONCRETE COATINGS WITH CONICAL INDENTER BY PARAMETERS OF RENEWED IMPRINT

摘要

Method for determination of hardness of asphalt-concrete coatings is in load fall from height on indenter with following calculation of hardness by parameters of imprint. At that angle of cone of indenter is chosen depending on type of coating and hardness is determined by formulae that take into account mass of load, height of its fall, angle of conicity of indenter and parameters of non-renewed imprint.
