Activities involving materials, research, and new products are administered by IDOT's Central Bureau of Materials (CBM). Administration of these activities requires CBM to develop new specifications or revise existing department specifications. Since these activities are under development or are being evaluated, the specifications do not have a wide distribution. In addition, these specifications are a working document and have not been adopted as a statewide standard.
There is no required training.
IDOT conducts specialized testing for Alkali-Silica Reactivity (ASR) ASTM C 1567, but also approves external laboratories to perform the test on its behalf.
If you would like to become an approved lab please contact the department for additional instructions.
