Effects Of Salt And Trace Minerals For Bituminous Pavement Literature Review, Information Gathering, And Research Plan Development, Robert Allan Pittenger, Terry R. West

JTRP Technical Reports

A review of current literature on the effects of deicing salt and trace minerals, such as sulfate, on aggregate deterioration was conducted. Such deterioration in both Portland cement concrete, and bituminous pavements was reviewed. For Portland cement concrete, it was determined that current research on the effects of moisture and deicing salt on aggregates concrete matrix durability, with little discussion on the effects on aggregates. The effects of trace minerals in deicing salt are also rarely discussed. Pore size distribution, insoluble residue, absorption, and susceptibility to alkali-silica reaction all appear to affect aggregate durability in the presence of moisture of …
