Quantitative Evaluation of Fog Seals on Pavement Skid Resistance with Indoor Accelerated Loading Tests

Fog seal is a simple and easily applied preventive maintenance treatment that has a positive role in protecting existing asphalt mixtures from oxidation, sealing small surface cracks and preventing pavements from raveling. However, the decline of pavement skid resistance after applying a fog seal treatment often limits its usage. This paper discusses the development of an accelerated loading system as a test platform to quantitatively evaluate the progression of pavement skid resistance on two common fog seal practices. The findings of this research can be used to further guide the placement of fog seal treatments.
