SB 102

The SB 102 Field Specialist certification is a one-day certification course that certifies an individual’s ability to properly sample and test soils and flexible base properties in the field in accordance with TxDOT Test Procedures.┬áThere is no demonstration or training; individuals must come prepared to pass examinations of associated test procedures through demonstration, verbal and practical methods. Once the evaluations are successfully completed, a final written examination is administered. A score of 80% or higher is necessary to obtain certification.

Test Procedures covered:

Tex-100-E Surveying and Sampling Soils for Highways
Tex-101-E Preparing Soil and Flexible Base Material for Testing (Part III)

Every three (3) years all SB 102 Field Specialists are required to re-certify. The re-certification course is a one day course.

A Specialist can attend a re-certification class up to one year prior to the expiration date. If certification expires, Specialists will lose certification and be issued a new certification date upon completion of another SB 102 training and certification class.
