The effect of the Superpave defined restricted zone on HMA rutting performance was evaluated. One gradation that violated the restricted zone (TRZ) and two gradations that did not violate the restricted zone (BRZ and ARZ) were evaluated. Mixes evaluated represented a range of maximum aggregate sizes (MAS), design traffic levels, and aggregate types. Three(More)
According to the principle of the acquisition of lateral multi-lens video logging images, the distortion correction method based on camera calibration model is proposed. The proposed method is consisted of two steps. Firstly, space conversion. According to the image model, transform three-dimensional space coordinate into 2D image plane coordinate,(More)
