Soils and Aggregate Testing Laboratory
Soils and Aggregate Testing
The soil and aggregate lab is equipped with all traditional equipment for characterizing the aggregates and index tests. One MTS system is dedicated to conducting resilient modulus and permanent deformation tests on bases and subgrades. The system is equipped with the latest fully-automated software for data collection and analysis.
In addition, two computer-controlled systems for conducting strength tests such as triaxial and unconfined compressive strengths, a computer-controlled direct shear tests and two computer-controlled devices for consolidation tests are available. Advanced nondestructive testing devices such as bender elements and resonant column for modulus, dielectric constant probes for moisture susceptibility are available.
Resilient Modulus & Permanent Deformation Testing: To assess behavior of unbounded geomaterials subjected to repeated loading and at different confinement and stress levels.
Small Scale Pavement Testing: Large-scale laboratory testing is an inexpensive test that provides well-controlled conditions in terms of compaction, environmental conditioning and instrumentation under actual field conditions.
Compression Testing Machine:: To determine both the unconfined compressive strength and the indirect tensile strength of geomaterials.
Static & Dynamic Compactor: To mold specimen for specified moisture and density. Typically used for developing moisture-density curve..
Large Scale MTS Testing Device: A 600-kip system used for large scale dynamic and static load testing..
Sigma 1 Shear Testing Devices: To measure the shear strength of soils at different confining pressures.
Wet Ball Mill & LA Abrasion: To determine the resistance of aggregate in flexible base material to disintegration or degradation.
FFRC and V-meter: FFRC and V-meter are used to measure elastic modulus based on wave propagation theory.
