Joint Design Optimization
PROJECTS UNDERWAY SOON Annual Meeting -MAY 24, 2021Steven Sachs PI: Julie Vandenbossche, PhD, PE ich 1 University of Pittsburgh | Swanson School of Engineering
Research Problem Goal: Long-term performance of the joints in JPCP with minimal maintenance activities Jt Performance is dependent on the interaction of individual elements of the pavement structure like…. • Load transfer • Jt reservoir/sealant design But also…. • Concrete durability • Quality of construction • Traffic level • Maintenance activities University of Pittsburgh | Swanson School of Engineering
Research Problem Goal: Long-term performance of the joints in JPCP with minimal maintenance activities Jt Performance is dependent on the interaction of individual elements of the pavement structure like…. • Load transfer • Jt reservoir/sealant design But also…. But typically designed • Concrete durability evaluated/independently • Quality of construction of one another • Traffic level • Maintenance activities University of Pittsburgh | Swanson School of Engineering
Project Objectives
Project Focal Points: Joint sealant: o Effectiveness: Early-age and long-term performance o Identify opportunities for improvement
Corrosion resistant dowels: o Corrosion models and dowel corrosion performance data will be identified and evaluated to determine which can be incorporated into currently fault development models
University of Pittsburgh | Swanson School of Engineering
Project Approach
Task A: Literature review on joint performance o o o o
Reservoir design Sealing Innovative sealant materials Dowel bar performance data and corrosion models
Task B: Performance review o Info request from Allegheny County, Turnpike & PennDOT • Design/performance/Maintenance/CPR
o Two site visits
