The objective of this study was to evaluate long-term aging effects on asphalt mixtures using the Illinois Flexibility Index Test (I-FIT) and to develop a corresponding long-term aging protocol. The study recommended the use of the forced-draft oven as the aging equipment because of its availability, feasibility, practicability, capacity, and acceptable...

When the sightlines along horizontal roadway curves are restricted, there are challenges to find acceptable solutions. Designers compensate for the limitations on driver sight distance in various ways, including: accepting shorter sightlines, lowering design speed, increasing shoulder width, or providing additional signage. There are advantages and...

Crack sealing is an important preventive treatment in the pavement preservation program. To achieve a cost-effective crack seal, it is important to select a proper crack sealing method. While Minnesota usually seals cracks in asphalt pavements, there is no clear consensus on the most appropriate crack sealing method for a specific job. This study focused on...

New shared mobility services have become increasingly common and transportation agencies are beginning to integrate them into regional planning processes. This report provides three case studies of how metropolitan planning organizations (MPOs) and their regional partners are integrating shared mobility into regional multimodal transportation planning. The...

The Smart Work Zone Speed Notification (SWZSN) system aims to alleviate congestion, queuing, and rear end crashes in work zones by informing drivers of the speed of the downstream segment using a type of portable Intelligent Lane Control System (ILCS), Portable Changeable Message Signs (PCMS). The hypothesis was that drivers, knowing the speed up to 1 mile...

Louisiana Transportation Research Center (LTRC) has conducted a research study on LA 493 that provides evidence of damage to roadways caused by inundation. The evidence supporting this comes from three sources: a rod and level cross-section survey taken approximately one month prior to the first inundation event and subsequent cross-section surveys taken after...

The objective of this research project was to develop methodologies for the evaluation of different types of seal-coated, gravel, and dirt roads by using a best-practice-oriented pavement-management system in Illinois. A statewide survey comprised of 13 questions collected 133 responses from county engineers and highway commissioners. Many counties and...
