Welcome to the ACIM Laboratory at Texas A&M University

Who We Are

The Advanced Characterization of Infrastructure Materials (ACIM) laboratory is a state-of-the-art facility for advanced materials characterization, nondestructive evaluation and computational modeling of infrastructure materials. The laboratory was established by the Zachry Department of Civil Engineering and the Texas Transportation Institute (TTI).

What We Do

The ACIM laboratory includes equipment and analysis tools for three-dimensional nondestructive imaging of material microstructure, mineralogical analysis of aggregates, quantitative image analysis of aggregate shape characteristics, measuring surface free energy of asphalt binders and aggregates, characterization of adhesion between various material and pavement systems using micro-structural analysis and continuum mechanics.

The ACIM laboratory compliments the existing civil engineering and TTI laboratories that include almost all standard tools and equipment required for specimen fabrication and mechanical testing of infrastructure materials such as:

  • Equipment for rheological characterization of materials
  • Geotechnical testing equipment
  • Ground penetrating radar
  • Gyratory compactors
  • Small scale load testers
  • Universal testing machines capable of conducting several AASHTO and ASTM tests

Setting the Standard

This facility provides tools that set the current trend in industrial and academic research in the field of infrastructure materials. In several cases, either the test equipment or the test protocol for using the equipment have been developed in-house by the materials group of the Zachry Department of Civil Engineering and TTI.
