Hits: 2247. A fog seal is a light application of a diluted slow-setting asphalt emulsion to the surface of an aged (oxidized) pavement surface. Fog seals are low-cost and are used to restore flexibility to an existing HMA pavement surface. They may be able to temporarily postpone the need for a surface treatment or non-structural overlay.
A fog seal is a light application of a diluted slow-setting asphalt emulsion to the surface of an aged (oxidized) pavement surface. Fog seals are low …
The results show that the chip seal with a fog seal layer on its top provides a dense surface with adequate skid resistance, aggregate-asphalt adhesive strength and inter-layer shear resistance. Im JH [27] spread the fog seal over the chip seal, analyzed the composite seal using the British pendulum number (BPN) and three-dimensional (3D) …

Process. Slurry seal consists of a carefully designed mixture of asphalt emulsion (which may be polymer-modified), mineral aggregate, water and additives; proportioned, mixed and uniformly spread over a properly prepared surface at a single stone thickness. Slurry seal is applied as a homogenous mat which adheres firmly to the prepared surface ...
410.2.3. This guide specification is intended to provide information needed for owners or contractors to construct emulsified asphalt fog seals. An emulsified asphalt fog seal is the application of emulsified asphalt, either diluted or undiluted, to a prepared pavement surface and may be followed immediately by a light application of blotter sand.
Fog seal—An application of asphalt applied on top of a pavement surface. Fog seals are commonly used on oxidized pavements to provide resistance to water intrusion and raveling. Fog seals are also used on newly constructed chip seals to promote adhesion and enhance aggregate retention.
