Corrosion Resistant Concrete Pavement Humidifier

Update date: Aug 23

The 1993 AASHTO pavement design guide indicates that dowel bars “should be resistant to corrosion when used in those geographic locations where corrosive elements are a problem.” [6] However, determining a dowel bar’s corrosion resistance is difficult because corrosion generally occurs slowly over the life of a concrete structure

    Corrosion of Embedded Metals. Corrosion of reinforcing steel and other embedded metals is the leading cause of deterioration inconcrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expansion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling
