Michigan's Inventory-Based Rating System For Unpaved Roads, Peter Torola Mar 2020

Michigan's Inventory-Based Rating System For Unpaved Roads, Peter Torola

Purdue Road School

The current rating systems for unpaved roads lack stability and reliability and, therefore, provide little benefit as project- or network-level metrics. Since many of these systems are derived from paved-road assessment systems, they focus heavily on surface distresses rather than road width, drainage, and other features. This session presents the Inventory-Based Rating System as a stable and implementable method of condition assessment for unpaved roads, without the focus on surface distresses.

Damage Evaluation Of Full-Scale Rc Slab By Ultrasonic Tomography, Hiroshi Hayashida, Tamon Ueda Nov 2019

Damage Evaluation Of Full-Scale Rc Slab By Ultrasonic Tomography, Hiroshi Hayashida, Tamon Ueda

International Conference on Durability of Concrete Structures

There have been reports of road bridges that deteriorated after their RC slabs had been repaired. The insufficient removal of damaged materials is said to be the cause of such post-repair deterioration. Consequently, there is a call for a survey method that can detect deteriorated materials of bridges with high accuracy. Towards the development of such a method, this report focuses on ultrasonic tomography, because it can detect damage to the RC slabs of road bridges over relatively large areas. We examined the applicability of ultrasonic tomography to a method of assessing the RC slab damage by a test that ...

Will Blended-Cement Systems With Similar Chloride Penetration Potentials Resist Similarly To Corrosion?, William Wilson, Vincent Labattaglia, Arezki Tagnit-Hamou, Luca Sorelli Nov 2019

Will Blended-Cement Systems With Similar Chloride Penetration Potentials Resist Similarly To Corrosion?, William Wilson, Vincent Labattaglia, Arezki Tagnit-Hamou, Luca Sorelli

International Conference on Durability of Concrete Structures

The capacity of concrete to prevent chloride ions penetration represents a key durability factor for steelreinforced structures exposed to de-icing salts and/or marine environments. Although blended-cement systems are commonly characterized with accelerated chloride penetration tests developed for Portlandcement concrete (e.g. the ASTM C1202 method), their microstructures and pore solutions are very different. This study aims to illustrate how the full potential of blended-cement systems to resist chloride ingress (and thus, chloride-induced corrosion) may not be justly disclosed by these accelerated tests using electrical current, even when tested after three months of curing. A Portland-cement-only mortar and five binary ...
