The Institute for Transportation at Iowa State University has released a report that seeks to provide guidance for the development of project specifications for internally cured concrete projects. Internal curing is a way to supply additional curing water – which may improve the hydration of cement, reduce autogenous shrinkage, and improve durability – throughout the concrete mixture.

The Institute for Transportation at Iowa State University has released a report that develops guidance about how husbandry loads are resisted by traditional bridges, with a specific focus on bridges commonly found on the secondary road system: steel-concrete, steel-timber, and timber-timber. This report also provides recommendations for accurately analyzing bridges for these loading effects, and offers suggestions for the rating and posting of these bridges.

The Institute for Transportation at Iowa State University has released a report that addresses the miscalculations in interchange crash models and introduces a new procedure for correcting crash locations.

The Institute for Transportation at Iowa State University has released a report that introduces a model that aims to more accurately estimate design and cost efforts for bridges.

The Institute for Transportation at Iowa State University has released a report that seeks to identify risk factors for traffic crashes on two facility types in Iowa: intersections and horizontal curves.

The Institute for Transportation at Iowa State University has released a report that discusses strategies for preventing or limiting premature joint deterioration due to salt reactivity and joint saturation.

The Texas A&M Transportation Institute has released a report that discusses how oversize/overweight (OS/OW) corridors are currently designated in Texas, and potential metrics that can be used for designated and monitoring OS/OW corridors.

The Massachusetts Institute of Technology has released a report that describes the development of a new engine weight surrogate model and High Pressure Compressor polytropic efficiency correction for the propulsion module in the Transport Aircraft OPTtimization (TASOPT) code.

The Mineta Transportation Institute at San Jose State University has released a report that describes models and data that permit a quantitative assessment of the significance of park-and-ride on transit efficiency.

The University of Illinois Center for Transportation has released a report that assesses the practice of timber pile retrofitting; investigates load rating and fiber reinforced polymers (FRP) retrofitting of abutment timber piles; and considers the long-term performance of FRP-wrapped timber piles.
