“…Further, it shows that laboratory tests that use equal times for drying and wetting increase the saturation level of the concrete over time. Researchers (Wang et al 2005) observed an increase in sample mass during wetting and drying cycling with deicers which was attributed to microcracking; however an increase in mass would be consistent with the wetting and behavior observed in this paper. The relative humidity of different salt solutions presented in Figure 5.7b help to understand the results from the drying tests.…”

“…The highest LCAs are achieved for the calcium chloride dihydrate solution. Calcium chloride can cause the most severe damage in Portland cement concrete by producing pressure (through osmosis) and crystallization or corrosion (Wang et al 2006). Presence of water-repellent materials can inhibit the penetration of detrimental chemicals from the surface, resulting in reduction of damage related to corrosion and salt scaling; the chemicals can still penetrate the concrete from the sides and the bottom of the slabs used in rigid pavements.…”

Sustainable super water/ice-repellent pavements are gaining attention as a smart solution for mitigating problems associated with winter pavement maintenance of roadways and airfields. Such smart pavements can facilitate surface drainage and prevent or curb ice formation or snow accumulation. While a conventional method for melting ice and snow is the use of deicing chemicals, such materials can transfer to the surface of nanotechnology-based pavements and influence their water/icerepellency by changing the chemistry of water or ice. This study focused on characterizing the degree of hydrophobicity of Portland cement concrete (PCC) nanocoated with polytetrafluoroethylene/polyetheretherketone (PTFE/PEEK). A layer-bylayer (LBL) spray deposition technique was used for spraying the binding agent and water-repellent materials. The liquidrepellency was characterized by measuring the static liquid contact angles (LCAs) and calculating the works of adhesion (WA). The liquid types used included distilled water and two types of deicing chemicals prepared by dissolving salts in distilled water. Data analysis results revealed that salt contamination improves the waterrepellency of nano-coated surfaces.

“…However, porous asphalt is not chemically affected by chloride and therefore does not suffer the chloride related spalling decay of porous concrete alternatives (Wang, Nelsen, & Nixon, 2006;Flatt, 2002). This durability to chloride may explain the 13% better performance of porous asphalt than precast porous concrete at City Lot #4.…”

Engineered porous media are commonly used in low impact development (LID) structures to mitigate excess stormwater in urban environments. Differences in infiltrability of these LID systems arise from the wide variety of materials used to create porous surfaces and subsequent maintenance, debris loading, and physical damage. In this study, infiltration capacity of six common materials was tested by multiple replicate experiments with automated mini-disk infiltrometers. The tested materials included porous asphalt, porous concrete, porous brick pavers, flexible porous pavement, engineered soils, and native soils. Porous asphalt, large porous brick pavers, and curb cutout rain gardens showed the greatest infiltration rates. Most engineered porous pavements and soils performed better than the native silt loam soils. Infiltration performance was found to be related more to site design and environmental factors than material choice. Sediment trap zones in both pavements and engineered soil rain gardens were found to be beneficial to the whole site performance. Winter chloride application had a large negative impact on poured in place concrete, making it a poor choice for heavily salted areas.
