The invention relates to technology of quality control of building materials, in particular to analysis of asphalt concrete properties, as well as ingredients of composite materials and can be used in road-airfield construction. A rapid method of quality control of asphalt concrete mixes and ingredients thereof comprises steps of measuring a parameter associated with a dielectric characteristic, measuring tangent of angle of dielectric losses (tgδ) and dielectric capacitivity (&egr;) by the values of which coefficient of dielectric power absorption K=&egr; tgδ is determined, comparing with the pre obtained value of similar composition corresponding to a finished material sample and with the value of the coefficient of dielectric power absorption and with value of coefficient of dielectric power absorption within K±20%, building material is considered to be qualitative. The present rapid method provides the control of quality of ingredients of asphalt concrete mix - bitumen and a mineral powder. |
