ICT Researchers Recommend Best Strategies for IDOT Effectiveness in Meeting Real-Time Information Dissemination Requirements

Published May 1, 2016

New federal requirements mandate that states establish a system for disseminating travel times, lane closures related to traffic incidents, lane- and road-closing construction, and road weather conditions to drivers in real time along interstates and key routes within a state. In addition, the information must be available 90% of the time and have an 85% rate of accuracy.Read More

ICT and IDOT Projects Develop Accelerated Experimental Procedure to Assess Aggregate Properties

Published February 19, 2016

Aggregate properties have an impact on several aspects of asphalt pavement performance. One of the most important performance parameters of aggregate properties is frictional (skid) resistance, which is a factor in travel safety. Aggregates must also be tough and abrasion resistant to prevent crushing, degradation, and disintegration during production, transportation, and construction.Read More

ICT Research Identifies Improved Models for IDOT to Perform Condition Rating Survey Analysis

Published February 19, 2016

Pavement management systems (PMS) assist decision makers in finding effective strategies for constructing, maintaining, and rehabilitating serviceable pavements over a given period of time for the least cost. Performance prediction models are an essential component of a PMS; they provide life expectancy estimates for pavements through cradle-to-grave monitoring of road conditions.Read More

ICT Investigates Nondestructive Methods to Evaluate Pavement Condition and Development of Improved Overlay Thickness Design Alternatives for IDOT

Published December 22, 2015

Local and state highway agencies dedicate a significant portion of their annual pavement management and rehabilitation budgets for assessing the condition of in-service pavements. To aid agencies in selecting an adequate, effective, and economical rehabilitation strategy, an accurate means for evaluating the functional and structural deficiencies of an existing pavement is necessary. For that reason, a project was initiated by the Illinois Department of Transportation (IDOT) to demonstrate the advantages of nondestructive testing (NDT) and evaluation for local agency pavement rehabilitation.Read More
