Academy of Pavement Science and Engineering Launched Today!

Published July 31, 2017

Registration is now open for joining the Academy of Pavement Science and Engineering (APSE), a global academic community aimed to educate, innovate, and advance the profession of pavement science and engineering. JOIN APSE.

In 2012, Illinois Center for Transportation Director Imad Al-Qadi invited a group of academic leaders from various educational institutions worldwide for a meeting where they formulated and debated a basic vision for how to advance pavement engineering education and research and set a new course for preparing the next generation of pavement engineers for professional practice. These academic leaders are the members of APSE’s Board of Governors: Professors Imad Al-Qadi, Bjorn Birgisson, John Harvey, Dallas Little, and Tom Scarpas.

On October 14, 2015, a group of academics (see list of founding members in APSE’s Directory) was invited to meet in Chicago and discuss the formation of APSE.  The group represented a wide spectrum of academics from research-active and education-focused institutes.  They came together to review, discuss, debate and further refine a vision for the development of a pavement science and engineering academic workforce with the knowledge and skills necessary to address the needs and the demands of the multi-trillion dollar infrastructure that underpins the world’s economies. The founding members worked meticulously behind the scenes to define the group and draft its mission, vision, and roadmap as related to its three core activities: Education, Research, and Professional Development.

APSE’s activities are facilitated by officers elected by the founding members: Amit Bhasin of the University of Texas, Austin (President); Silvia Caro of the University of Los Andes, Colombia (Vice-President); Ghassan Chehab of  the American University of Beirut, Lebanon (Secretary); and Elie Hajj of the University of Nevada, Reno (Treasurer).

ICT/IDOT Propose the First Oversize/Overweight Permit Fee Structure Incorporating Safety Cost Analysis

Published July 5, 2017

Trucking is the lifeblood of commerce for the State of Illinois. In order to ensure the infrastructure of the state can safely support the movement of goods and services, the state regulates oversized and overweight (OSOW) vehicles, such as semis and large trucks, using a fee-based permit system. This fee system had not been evaluated, to ensure fees correspond to the effects OSOW vehicles have on infrastructure, for several decades. IDOT recognized that this system needed to be reviewed and possibly revised. In support of this, Illinois Center for Transportation (ICT) researchers used a variety of state-of-the-art techniques to sort through data and model the impact of OSOW vehicles on bridges, roads, and safety, in order to develop a fair, justifiable fee structure. The findings for the project, “Development of a Proposed Overweight Vehicle Permit Fee Structure in Illinois,” are now available on ICT’s web site.Read More

Recent ICT Reports and New Projects

Published July 5, 2017

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

R27-153: Best Management Practices and Incentives to Expedite Utility Relocation. This report investigates the problem of construction delays caused by the relocation of utilities in Illinois construction projects and recommends several best management practices to help mitigate those delays. After conducting a thorough literature review, analyzing current IDOT practices, and comparing those practices to other states’ practices, investigators made several recommendations, checked those recommendations against state and federal laws, and made cost analyses of all options in order to develop a method for IDOT to choose which best management practices would best fit any given situation.

R27-160: Illinois Highway Materials Sustainability Efforts of 2016 . In compliance with the Illinois Public Act regarding the reduction of carbon emissions, this report details IDOT’s efforts to use recycled and reclaimed materials in construction projects in 2016. Over 1.7 million tons of reclaimed or recycled materials, valued at over $50 million, were used in Illinois highways in 2016, resulting in an estimated net reduction of carbon dioxide emissions of 166,195 tons.

R27-045-T1: Evaluation of 3-D Laser Scanning Equipment: 2016 Interim Report. This interim report details an evaluation of the Trimble TX5 3D laster scanning unit to determine the tangible costs and the manpower savings realized by using this equipment in place of or in conjunction with conventional surveying methods. Two projects in IDOT District 8 were studied, one using the laser scanner, one using convential surveying techniques, in order to compare manpower requirements. In addition, other project were used to test the scanner for other purposes, such as surface topography mapping of bridge decks, bridge beam deflection scans, and detailed surface mapping of various structures.  Further testing of this equipment is expected to take place in the coming construction season.

R27-152: Development of a Proposed Overweight Vehicle Permit Fee Structure in Illinois. The objective of this study was to revise the current permit system for the State of Illinois. Parts of this current system had not been updated in 30 years, so researchers looked at the impacts of overweight vehicles on bridges and pavements, and in traffic safety situations, and used state-of-the-art prediction/classification algorithms to produce a realistic, up-to-date assessment of the impact of overweight vehicles. The report details the methods and final fee determination researchers produced by combining the new data with known data on the miles traveled and axel and weight information used by the permitting system.

R27-172: Roadway Lighting’s Impact on Altering Soybean Growth: Volume 1. This project sought to measure the impacts of roadway lighting on soybean production. By measuring height, reproductive stage, plant moisture content, and other factors at seven different sites, researchers found strong evidence that roadway lighting had a significant impact on soybean crops and recommended ways to mitigate the effects.

R27-141: Effective Post-Construction Best Management Practices (BMPs) to Infiltrate and Retain Stormwater Run-off. Using a combination of field observations and computer simulations, researchers evaluated three types of storm-water prevention techniques, and combined that information with life-cycle analysis costs, in order to identify the most cost-effective solutions for managing runoff in post-construction highways. They also conducted full-scale field tests of bioswales and infiltration trenches. These different approaches provide key insights for developing guidelines for cost-effective best-management practices to control stormwater runoff.

R27-SP31: Evaluation of I-FIT Results and Machine Variability using MnRoad Test Track Mixtures. Researchers evaluated machines in various configurations for performing the Illinois Flexible Index Test (I-FIT). By comparing three machines and eight different asphalt concrete mixtures, they determined that the I-FIT test was stastisically independent of the equipment used for the procedure.

Additionally, the ICT Executive Committee has approved two new projects:

  • Evaluation of Various Tack Coat Materials Using Interface Shear Device and Recommendations on a Simplified Device (started May 1, 2017)
  • Behavior of Epoxy Coated Textured Reinforcement Bars (started May 15, 2017)
