CBM Specifications

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.
