Construction Materials Testing (CMT)
and Construction Materials Engineering (CME) Services



With fully equipped construction materials testing and engineering laboratories in both Tyler and Longview, Texas, and in Texarkana, Arkansas, plus highly
experienced laboratory and field personnel, ETTL has been carrying out
construction materials testing (CMT) and construction materials engineering (CME) projects for more than four decades, serving a multitude of clients.

 


|Booms from four mobile pumping units feed some 5000 cubic
yards of concrete during construction of a huge foundation for
a preheating unit at a new Ash Grove cement plant in western
Arkansas. A placement crew (next photo) waits for new concrete.

Meanwhile four teams of ETTL technicians (one team at each
boom) carry out tests of the incoming concrete, including slump,
air content and other variables, and also prepare test cylinders
for subsequent compression testing in ETTL laboratories.



ETTL's Construction Materials Testing and Engineering Capabilities


1. Construction materials formulation, especially of concrete and asphalt designs, as well as designs for soil stabilization, making use of various chemical additives to alter physical properties of soil.
2. Construction materials testing, not only of concrete and asphalt but of soil, road base and airport runway materials, as well as liners (both soil and plastic) for landfills; roofing materials; bridge bearing pads; and many other specialized testing situations, including placement and testing of fireproofing materials.
3. Monitoring placement as well as carrying out testing of soil and concrete in an extreme range of constructions including: highways, bridges and dams; landfills; foundations and piers for buildings and structures of all types.
4. Inspection of structural and reinforcing steel, including welds, bolts, and post tension cables, as well as rebar and rebar cages, making sure they are correctly sized and located.
5. Evaluating and trouble-shooting existing pavement installations: runways, roads, bridges and parking lots, plus such specialized constructions as heavy industrial pavements.
6. Soil Resistivity Testing -- helping clients make sure the grounding systems they are designing (or have already installed) will be compatible with the soil in which they are placed.
7. Pavement Design Services -- for roads, highways, parking areas -- for TxDOT and a wide variety of other clients.
8. Contract Soil Laboratory Testing Services -- Advanced ETTL laboratory equipment and services to test your soil and aggregate samples on a contract basis.
9. Forensic Investigations and Expert Witness Services.

The tests described are typical of those ETTL makes available to clients on a contract basis, as well as when our technical staff is carrying out construction materials and geotechnical testing and design projects. The "air board" equipment shown is used when performing a variety of the tests.

ETTL's CME Quality Control Program

ETTL participates in several proficiency sample testing programs, including those conducted by AASHTO Materials Reference Laboratory (AMRL); Cement & Concrete Reference Laboratory (CCRL); and TxDOT Materials & Test Division Bituminous Proficiency Sampling. As part of their routines, the programs involve ETTL's laboratory facilities, which run tests on representative samples prepared by these agencies. ETTL's home office is audited every second year by AASHTO, which accredits ETTL's CME services. (Click here to see AASHTO's accreditation details for ETTL on the AASHTO web site.)

In addition, ETTL meets the requirements of ASTM E 329.

ETTL also has been inspected and approved for work by the Texas Department of Transportation. And, as the need arises, ETTL has been inspected and approved by the Corps of Engineers for work on various Corps projects within ETTL's geographical service area.

ETTL has TxDOT Precertification in a number
of key areas. Click here to see listing.
