Construction Materials Testing & Engineering Services

With fully equipped construction materials testing and engineering laboratories
in Tyler and Longview, Texas, and Texarkana, Arkansas, and highly experienced
field personnel, ETTL has been carrying out construction materials testing (CMT)
and engineering (CME) projects for four decades, serving a multitude of clients.
The Company serves these clients in nine major areas of expertise:

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 (a gyratory compactor used in the HVEEM method of asphalt analysis is shown at right), 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. Click links in table below for more information.
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; and foundations for buildings 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. Click link in table below for more information.
5. Evaluating and trouble-shooting existing pavement installations: runways, roads, bridges and parking lots, plus such specialized constructions as heavy industrial pavements. Click link in table below for more information.
6. Soil Resistivity Testing -- helping clients clients make sure the grounding systems they are designing (or have already installed) will be compatible with the soil in which they are placed. Click link in table below for more information.
7. Pavement Design Services -- for roads, highways, parking areas -- for TxDOT and a wide variety of other clients. Click link in table below for more information.
8. Contract Soil Laboratory Testing Services -- Advanced ETTL laboratory equipment and services to test your soil and aggregate samples on a contract basis. Click link in table below for more information.

ETTL's CME Quality Control Programs

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.
