Abstract
Изобретение относится к области технологии проверки качества строительных материалов, в частности к исследованию свойств асфальтобетонных смесей, и может быть использовано в дорожно-аэродромном строительстве. В экспресс-методе контроля качества асфальтобетонных смесей и входящих в нее компонентов, включающем измерение параметра, связанного с диэлектрической характеристикой, измеряют тангенс угла диэлектрических потерь (tgδ) и диэлектрическую проницаемость (ε), по значениям которых определяют коэффициент диэлектрического поглощения энергии K=ε∙tgδ, сравнивают с предварительно полученным значением этого же параметра, соответствующего готовому образцу материала того же состава, и при значении коэффициента диэлектрического поглощения в пределах K±20% сравниваемого значения, строительный материал считают качественным. Данным экспресс-методом осуществляют контроль качества составных компонентов асфальтобетонной смеси - битума и минерального порошка.The invention relates to the field of technology quality control of building materials, in particular to the study of the properties of asphalt mixes, and can be used in road and airfield construction. In the express method of quality control of asphalt concrete mixtures and its constituent components, including the measurement of the parameter associated with the dielectric characteristic, measure the dielectric loss angle (tgδ) and dielectric constant (ε), the values of which determine the coefficient of dielectric absorption of energy tgδ, is compared with the previously obtained value of the same parameter corresponding to the finished sample of material of the same composition, and with the value of the dielectric absorption coefficient in the range lakh K ± 20% of the compared value, the building material is considered to be of high quality. This rapid method controls the quality of the constituent components of the asphalt concrete mix - bitumen and mineral powder.
