Materials Testing
GES has three construction materials testing laboratories in Nevada. These laboratories have state-of-the-art equipment for testing soils, concrete, masonry, asphalt and aggregates following strict quality assurance guidelines for equipment usage and calibration.
GES is familiar with specifications from various agencies such as state and federal highway departments, ASTM, FAA, FHWA, AASHTO and U.S. Army Corps of Engineers. GES’ staff and laboratories are inspected by CCRL and AMRL, and then certified by AASHTO and the respective state departments of transportation.
LABORATORY TESTING
GES provides materials testing on:
Soils
Laboratory tests are performed to define soil properties and identify those soils that do not conform to project specifications. For moisture content, strength and stability, the early identification of issues helps avoid future problems and allows for the correction of problems during construction.
Concrete & Masonry
New criteria for concrete and masonry construction are evolving on a continual basis. We can design mixes for concrete, mortar and grout to satisfy the project specifications.
Asphalt
Modern construction practices involving asphalt require consideration of such factors as durability, adaptability to fast track construction and proper performance under specialized applications. Asphalt concrete mixes can be designed using local materials that best fit roadway and airport needs.
Aggregates
Aggregate quality is established and monitored by performing such laboratory tests as gradation analysis, specific gravity, absorption, soundness, freeze-thaw, abrasion, deleterious substances, and acid solubility.
ON-SITE OBSERVATION AND MONITORING
On-site testing and observation requires licensed professional engineers and ACI/NAQTC certified technicians. GES personnel are trained in the areas of ASTM requirements, equipment usage, and health and safety. On-site services typically fall into one or more of the following categories:
- Soils
- Concrete & Masonry
- Asphalt
- Aggregates
