Field permeability test using NCAT Permeameter were conducted at four project sites before and after the application of fog seal. Due to the fact that it is difficult to estimate the thickness of pavement tested, instead of permeability, the infiltration rate is calculated to estimate the effectiveness of fog seal on reducing the permeability of pavement.;Cores from I-79, I-64 and Route-19
