The IDOT Pavement Technology Advisories (PTAs) are now
available online! Compiled by the Bureau of
Materials and Physical Research (BMPR), these short
informational documents cover a wide variety of
topics pertinent to highway engineering at IDOT.
The PTAs are categorized into three main topic
groups: 1. Design, Construction, and Materials; 2.
Maintenance, Repair, and Rehabilitation; and 3. Testing
and Data Collection. In this way, topics of interest
from each stage of a typical highway’s life-cycle are
Each PTA also contains information on who to contact
to learn more about a topic. The PTAs provide a valuable
resource to anyone interested in highway engineering,
and can be particularly useful to highway agency
personnel responsible for planning, designing, building,
and/or maintaining roads.
