Recent ICT-IDOT report publications

11/1/2018

Several reports from recently completed, IDOT-sponsored projects are now available on ICT’s website: 

R27-168: Field Performance Evaluation of Sustainable Aggregate By-product Applications. This report focuses on introducing and evaluating new sustainable applications of Quarry By-products (QB) and/or QB mixed with other marginal, virgin, or recycled aggregate materials in pavements.

R27-157: Plasticity Requirements of Aggregates Used in Pavement Base and Subbase Courses. This report documents the review and update of the requirements of crushed aggregates in terms of the percentage passing amount and the properties of aggregate fines in pavement unbound base and subbase applications.

R27-149-2: Material Constituents and Proportioning for Roller-Compacted Concrete Mechanical Properties. The main objective of this report was to investigate the effects of mixture parameters and compaction methods on laboratory properties of Roller-Compacted Concrete (RCC).

R27-133: Seismic Performance of Seat-Type Abutment Highway Bridges in Illinois. This study assesses the seismic performance of quasi-isolated highway bridges with seat-type abutments, validates the current Illinois Department of Transportation design strategy, and provides recommendations for improving a bridge’s seismic behavior.

R27-133: Seismic Performance of Integral Abutment Highway Bridges in Illinois. This report examines the seismic behavior of typical Integral Abutments (IABs) in southern Illinois and develops feedback and recommendations for improving IAB seismic designs.

R27-169: Opportunistic Traffic Sensing Using Existing Video Sources (Phase II) Final Report. This report examines effective ways to both collect and produce traffic data using several video sources. It also documents the adjustments made to the algorithms used in Phase I of the project. This would improve accuracy and robustness to adverse environmental and lighting conditions. Phase II also introduces a web portal interface for using the system remotely.
