Decision Tree Planning for Surface Conditions

Pavement Analyst (PA) has enhanced the effectiveness and efficiency in the planning, construction, and management of the state highway infrastructure. PA helps make informed and objective decisions about maintenance and rehabilitation activities. Historically, these decisions have been based on structural conditions (e.g., condition, ride and/or distress scores). This project will define and incorporate surface condition elements (i.e., macrotexture, microtexture, friction, skid number, cross-slope, etc.) in the decision trees to improve safety conditions when low levels are detected, particularly in areas that have been identified as problematic.
