Asphalt pavement compaction uniformity evaluation method based on ground penetrating radar
The invention belongs to the field of road engineering, and particularly relates to an asphalt pavement compaction uniformity evaluation method based on a ground penetrating radar. The method comprises the following steps: firstly, deducing a calculation formula of the maximum theoretical compaction degree of an asphalt surface layer by establishing a dielectric model of an asphalt mixture; then preparing an asphalt mortar test piece and an asphalt mixture test piece in a room according to a mixing ratio, carrying out amplitude data acquisition by using a ground penetrating radar, and calculating dielectric constants of the asphalt mortar and the asphalt mixture; then combining the mix proportion parameter of the asphalt mixture and the measured dielectric constant, and carrying out back calculation to obtain the dielectric constant of the aggregate; after the obtained key parameters are adopted, the compactness of the asphalt pavement on site is detected through radar amplitude data collection; finally, nondestructive and efficient detection and evaluation of the compaction degree of the asphalt surface layer are achieved through data evaluation. The method has the advantages of being non-destructive, easy and convenient to operate, high in detection efficiency and the like, and powerful technical support can be provided for quality control and evaluation of the asphalt pavement.
