Permeability of asphalt mixtures exposed to freeze–thaw ...

Mar 01, 2016  This paper discusses the permeability of asphalt mixtures exposed to freeze–thaw cycles. Three types of asphalt mixtures, namely, AC-13, SMA-13, and OGFC-13, were used for the test. A special constant head permeameter following the UNI EN 12697/19 protocol was adopted to evaluate the permeability of asphalt mixtures under freeze–thaw cycles.

One of the primary objectives when constructing hot mix asphalt concrete (HMAC) is achieving the target density in order for the pavement to be impermeable. If the density is too low, water infiltration causes pavement damage from freeze-thaw and other effects caused by the presence of water. If the pavement density is too high, rutting, flushing, and shoving will occur.;This research used the ...
