Abstract

Изобретение относитс  к дорожному строительству, а именно к контролю качества работ. Цель изобретени  - оценка качества слоев из несв зных материалов. Способ осуществл ют следующим образом. Перед устройством очередного конструктивного сло  дорожной одежды на поверхности ранее построенного сло  или на поверхности подстилающего грунта вдоль дороги непрерывно измер ют интенсивность естественного гамма-излучени  с построением линейного графика 1. После устройства конструктивного сло  осуществл ют повторное измерение естественного гамма-излучени  на его поверхности с построением линейного графика 2, а о качестве сло  суд т по разности интенсивностей гамма-излучени  до и после устройства сло . 1 ил.FIELD OF THE INVENTION The invention relates to road construction, namely to the quality control of work. The purpose of the invention is to assess the quality of layers of non-bonded materials. The method is carried out as follows. Before the next structural pavement device is installed, the natural gamma radiation intensity is continuously measured on the surface of the previously built layer or on the surface of the underlying soil along the road with the construction of a linear graph 1. After the structural layer is constructed, the natural gamma radiation on its surface is re-measured with the construction line graph 2, and the quality is judged by the difference in the gamma-ray intensities before and after the layer device. 1 il.

Description

Изобретение относится к дорожному строительству, а именно к контролю качества работ.The invention relates to road construction, namely to quality control of work.

Цель изобретения - оценка качества слоев из несвязных материалов. 5The purpose of the invention is the assessment of the quality of layers of disconnected materials. 5

На чертеже показан пример линейного графика изменения естественного гаммаизлучения на поверхностях нижележащего и вновь устраиваемого конструктивных слоев дорожных одежд.The drawing shows an example of a linear graph of changes in natural gamma radiation on the surfaces of the underlying and newly arranged structural layers of pavement.

Способ осуществляют следующим образом.The method is as follows.

Перед устройством очередного конструктивного слоя дорожной одежды из несвязного материала на поверхности ранее построенного конструктивного слоя или на поверхности уплотненного грунта земляного полотна вдоль строящейся дороги непрерывно измеряют интенсивность естественного гамма-излучения поверхно- 20 сти слоя или грунта с построением линейного графика 1, показанного на чертеже. После устройства очередного конструктивного слоя дорожной одежды осуществляют повторное измерение естественного гамма-излучения поверхности этого слоя с построением линейного графика 2. О хорошем качестве построенного конструктивного слоя судят по разности интенсивностей гамма-излучения до и после устройства слоя, превышающей нулевое значение.Before the next structural layer of pavement of incoherent material is arranged on the surface of a previously constructed structural layer or on the surface of compacted soil of a subgrade along a road under construction, the intensity of natural gamma radiation of the surface of the layer or soil is continuously measured with the construction of a linear graph 1 shown in the drawing. After the installation of the next structural layer of pavement, a second measurement of the natural gamma radiation of the surface of this layer is carried out with the construction of a linear graph 2. The good quality of the constructed structural layer is judged by the difference in the intensities of the gamma radiation before and after the device layer exceeds zero.
