The effects of chloride-based deicing chemicals on degradation of portland cement mortars with alkali reactive aggregate
<p>The assessment of the influence of deicing chemicals on alkali reactivity of aggregates is still an area of active research, particularly with respect to the combined effects of long-term exposure to deicers, freezing and thawing cycles, and wetting and drying cycles. In order to develop a more …

Design and field testing of jointless bridges
… They are also a "weak link" that can allow deicing chemicals to seep down and corrode bearings and support components. Because the design is difficult and their behavior is unknown, they are not widely used despite the enormous benefits. There are no standardized design procedures for these …

Comprehensive investigation of using tire-derived aggregate in chip seal subjected to various traffic and environmental conditions
… and low temperature; resistance to freeze-thaw, deicing chemicals, and snowplowing action; and drainage capability of rubberized and conventional chip seal was assessed and compared in this research. For this means innovative traffic and rainfall simulation devices were manufactured and used. A …

Evaluation of Field Tests Performed on an Aluminum Deck Bridge
… concrete girders. Over the years, weathering and deicing chemicals have caused spalling of the concrete surrounding the reinforcing steel, deteriorating many bridges to levels that often result in closure. Repairing or reconstructing the reinforced concrete deck to meet current design …

Durability behavior of fiber reinforced polymer and steel reinforced polymer for infrastructure applications
… over time, because they allow chlorides from deicing chemicals to infiltrate concrete which will then corrode steel bars as RC structures are exposed to harsh weather. In the last decade, composite reinforcement systems are internally or externally applied to concrete structures instead of …

Tensile Testing of Cold-Applied Joint Sealants
… commonly used in pavement joints to keep debris, deicing chemicals, and moisture out of the joint. When a joint sealant fails, the pavement can quickly deteriorate; however, when a joint sealant functions well, the pavement maintains its intended performance. Joint sealants are subjected to two …

A hierarchical analysis of factors affecting the adoption and marketing of timber bridges
… include: year around construction, resistance to deicing chemicals, quick construction, and aesthetic qualities. Major barriers appear to be: short lifespan, maintenance requirements, decay, perceptions of strength, and that "timber doesn't perform well under high weight and traffic volumes". The …

Shear Strength Assessment of Corrosion-Damaged Prestressed Concrete Girders Repaired With CFRP
… multiple agents such as marine environments or deicing chemicals. The damages caused by these agents, if left unmitigated, may lead to failure of the superstructures. If corrosion is present in the end regions of the beams, failure of the girders will likely be in shear, which is a sudden …

Performance-Based Evaluation of Joint Sealants for Concrete Pavements
… in pavement joints to prevent roadway debris, deicing chemicals, and moisture from entering the joint. When sealant fails, the pavement deteriorates rapidly; and when joint sealant performs adequately, the pavement preserves its intended performance. In the field, joint sealant undergoes two …

Seismic behavior and design of integral abutment bridges in southern Illinois
… stub abutment bridges because water, soil, and deicing chemicals are unable to penetrate through a compromised expansion joint in an IAB. However, elimination of expansion joints in IABs can also lead to the development of complex soil-structure-interaction limit states at the abutment and its …

In situ Nanoscale Quantification of Corrosion Kinetics by Quantitative Phase Microscopy
… was presented. The extensive application of deicing salts has led to significant deterioration in many transportation infrastructures and automobiles due to corrosion. In this regard, the work investigated the corrosion inhibition performance of 2 corn-derived polyols, namely: sorbitol, and …

Verifying the Calcium Oxychloride Threshold in Cementitious Pastes
… chloride (CaCl2) or magnesium chloride (MgCl) deicing salts and calcium hydroxide in the cementitious matrix. Currently, the accepted CAOXY threshold at which deterioration is mitigated in cementitious paste is 15 g/100 g paste (15 oz/100 oz paste); however, this limit was developed using …
