Pavement Technology Advisories (PTA)
PTAs are short informational documents covering a wide variety of topics pertinent to highway engineering at IDOT and are a valuable resource to anyone interested in highway engineering - planning, designing, building, and/or maintaining roads. PTAs are categorized into three main topic groups: Design, Construction, and Materials; Maintenance, Repair, and Rehabilitation; and Testing and Data Collection.
