Flat and Elongated: Advances using Digital Image Analysis

  title={Flat and Elongated: Advances using Digital Image Analysis},
  author={Norbert H. Maerz and Wei Zhou},
Coarse aggregate shape (flat and elongated) is an important issue in the highway industry. Elongated aggregates tend to break down during the asphalt emplacement process. Flat aggregates tend to lay flat, imparting anisotropic properties to the finished product. The new Superpave guidelines call for no more than 10% of coarse aggregates to have aspect ratios greater than 5:1, and there is a possibility of a new standard at 3:1. Digital image processing is a new approach to measuring these…

Differences in the surface texture of aggregate particles determined by 3D model derived from optic microscope measurements

The surface texture of aggregate particles was investigated based on the 3D model of surface generated from the measurements by optic microscope. New software MicroSYS was developed to determine the

Dimensional Ratios for Stone Aggregates from Three-Dimensional Laser Scans

The ''laser-based aggregate scanning system'' ~LASS! was developed to rapidly and accurately characterize the three- dimensional shape properties of unbound stone aggregates. A linear motion slide, a

Ashac: An alternative towards classifying the shape of aggregate

A number of image analysis applications are already available to classify the shape of aggregate. These applications were evaluated and compared with our new alternative application called aggregate

Three-Dimensional Digital Image Processing And Reconstruction Of Granular Particles

This thesis presents a method for digitization of the two-dimensional shape of granular particles by means of photo microscopy and image processing techniques implemented using a software package

Test Methods for Characterizing Aggregate Shape, Texture, and Angularity

The test method measures shape, texture, and angularity characteristics of aggregates used in hot-mix asphalt, hydraulic cement concrete, and unbound base and subbase layers of highway pavements, and it is appropriate for use in central and field laboratories.




Aggregate size and shape measurements are increasingly becoming important issues in the mining, comminution, materials handling, and construction industries. Screening or sieving methods, today’s

Morphological Study of Coarse Aggregates Using Image Analysis

A newly developed digital image-analysis method was used to characterize the morphological characteristics of coarse aggregates. Regression analyses found that the imaging morphological
