This paper presents a data-driven deicing management framework to minimize the environmental impact of airport deicing activities at Dallas-Fort Worth International Airport. Airplane deicing involves the use of aircraft deicing and anti-icing fluids with a high concentration of ethylene/propylene/diethylene glycol. The glycol shearing off the airplanes during taxiing and dripping to the runway ...

Describe various geographical environments in terms of their atmospheric corrosivity Summarize the main factors causing atmospheric corrosion Explain how these factors are measured Examine how the safety introduced by the massive usage of deicing salts has modified the corrosivity of road environments Design a testing program to establish the corrosivity map of a given site or even a country re...

Chemical deicing plays a fundamental role for traffic safety on roads and runways in winter season. Traditional deicing chemicals, such as sodium chloride and urea have, however, undesirable effects on surface and ground waters. For more sustainable road and runway winter maintenance, easily biodegradable organic salts such as acetates and formates, have been proposed and taken into use. Next t...

Road deicing salts are widely used during winter in northern China, which makes it essential to choose proper salt-tolerant plant species urban landscapes. Columbine (Aquilegia) is a herb with high ornamental and commercial values. This study evaluated three Aquilegia (A. oxysepala, A. parviflora, viridiflora) for salt tolerance by monitoring their germination state under different electrical c...

This paper is based on an experimental research that examined the effects of concrete`s major parameters on durability of concrete pavements and curbs under freezing and thawing cycles. These parameters include concrete mix design parameters such as water-cement ratio, fine aggregate percentage and using air entraining admixture and simulating real freeze-thaw cycles that infrastructures underg...

Aircraft deicing fluids rapid heating system is widely used in aircraft ground deicing to ensure that the operation of flights can be safe and efficient. Aiming at the temperature turbulence problem of aircraft deicing system, this paper presents the single neuron PID control strategy which combine the advantage of conventional PID control with artificial neuron control. The aircraft deicing fl...

Widespread and increasing use of road deicing salt is a major driver lake chloride concentrations, which can negatively impact aquatic organisms ecosystems. We used simple model to explore the controls on concentrations predict equilibrium in lakes across contiguous United States. The suggests that concentration depends three quantities: application rate, density, runoff (precipitation minus ev...
