Polymer-Modified MasterSeal (PMM) Ultra Pavement Sealer is an environmentally friendly mineral filled asphalt emulsion pavement sealer blended with polymers and special surfactants for superior adhesion, flexibility and durability. PMM Ultra is a higher solids, faster drying pavement sealer designed to beautify and protect asphalt pavement.
Fog seal consist of a light application of dilute, slow-setting asphalt emulsion or oils over the surface of an existing, weather-aged pavement. Fog sealing is good preventive maintenance, and it restores or rejuvenates an existing hot melt asphalt surface for a year or two.
There are two main types of surface treatments applied to extend the life of the pavement: Fog Seal and Slurry Seal. A fog seal is a thin layer of asphalt emulsion applied to the street surface to prevent oxidation, loss of fine aggregate and add asphalt material to the surface course.
A scrub seal is an application that is very close to a chip seal treatment where asphalt emulsion and crushed rock are placed on an asphalt pavement surface. The only difference is that the asphalt emulsion is applied to the road surface through a series of brooms placed at different angles.
A fog seal is a light application of asphalt emulsion to an existing paved asphalt surface. This type of maintenance treatment is primarily employed as an impervious sealer that will slow the rate of weathering of the asphalt in the underlying pavement.
A fog seal is an inexpensive way to rejuvenate and seal pavement surfaces. Fog seals are often applied on a routine schedule (typically every three to five years) to prolong pavement life. Fog Seal Benefits. The asphalt emulsion seals the pavement from water penetration. The treatment blackens pavement, adding differentiation to pavement lanes.

By maintaining pavement on a routine basis, the life cycle is lowered, pavement life is extended and future deterioration is delayed. Quality Tested Products and Services. Every pavement maintenance product that Wright creates is put through rigorous testing, quality control and certification before ever being introduced to the market.
Chip seals are relatively inexpensive, as compared to conventional hot mix asphalt overlays, and are fast and easy process (usually completed in 24 hours or less). A chip seal can extend pavement life by 5 to 7 years. Fog Seals. A fog seal is a light application of a diluted slow-setting asphalt emulsion to the surface of an aged pavement surface.
Fog Seal Application of REJUVENATORS & SEAL COATS John Calvert Consultant - Pavement Technology, Inc. ... Why use fog seal rejuvenators and seal coats? Both are valuable pavement preservation tools that can play a vital part in extending the useful life of asphalt pavements. ASPHALT PRICES January 2000 thru September 2008 $120.00 $150.00 $180 ...
Fog Seals are applied by properly calibrated asphalt distributors to achieve uniform coverage. The combination of binder read in the fog seal with chip seal provides a hard asphalt enriched pavement …
May 25, 2018· In some cases, additional ingredients known as rejuvenators may be added to a fog seal. Rejuvenators soften the existing asphalt binder, allowing the fog seal to more fully bond with the pavement. Purpose. Fog seal is a good choice for adding an extra layer of protection to an asphalt …
caused reductions in pavement friction and pavement marking retroreflectivity. The recovery period for friction was much shorter for nontraditional fog seal treatments when compared to an emulsified asphalt fog seal. Recovery of retroreflectivity occurred under traffic.
CHAPTER 6 FOG SEALS 1.0 INTRODUCTION Fog seals are a method of adding asphalt to an existing pavement surface to improve sealing or waterproofing, prevent further stone loss by holding aggregate in place, or simply improve the surface appearance. However, inappropriate use can result in slick pavements and tracking of excess material.
Fog Seal Is a mixture of aggregate, asphalt emulsion, Fog sealing is a method that is used to lock in chips in a chip seal or to coat a new hot mix surface to lock in fines and fill surface voids. It is not used for aged pavements usually for this a rejuvenation spray such as Styraflex™ ERA™ is recommended.
Fog seal applications serve to seal narrow cracks, slightly restore lost flexibility to the pavement surface, provide a deep, rich black pavement surface color, and most importantly help preserve the underlying pavement structure. When? On existing asphalt pavement, fog seals are typically applied on either an intermittent or cyclical basis.
Fog Seal. 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.
The flush coat consists of the application of a fog seal (see fog seal) followed by the application of very clean sand. The purpose of the flush coat is to help "lock down" the chips and absorb any excess asphalt emulsion. The result is a pavement surface that has a rough texture and a very deep, rich black in color.
"Fog Seal has been useful in slowing down the oxidation and raveling on our new roads. Residents have enjoyed having a road that looks freshly paved again and our pavement managers have enjoyed the added service life.
Fog Seal Fog seal is a light application of diluted, slow-setting asphalt emulsion, rejuvenator or bio seal product without aggregate cover. When used, the pavement surface must be dry, clean, and in good condition. A critical factor for fog seals is the application rate of the liquid asphalt or rejuvenator, which should be in the range of 0.05 ...
Preservation Using Rejuvenating Fog Seals. Major Professor: Dr. John Haddock Fog seal is a type of treatment that uses a diluted asphalt emulsion to seal and protect an existing asphalt surface from a variety of distresses. Fog seal is sprayed on top of an asphalt pavement surface to improve and protect it from further cracking and raveling.
This treatment is best performed to newer asphalt pavements to renew weathered asphalt surfaces and improve appearance, seal minor cracks and surface voids, and inhibit raveling. Fog Seals are also used to seal and prevent loose aggregate issues in chip seals.
AMS PAVEMENT PRESERVATION AMS MAINTENANCE: GRIP TIGHT FOG SEAL Grip Tight Fog Seal is a specialized emulsion designed specifically for the treatment of Chip Sealed pavements to effectively improve aggregate retention and provide a long …
According to the Pavement Preservation and Recycling Association (PPRA), a fog seal "is a single application, typically light, of emulsified asphalt to an existing asphalt surface." The fog seal is typically used on pavements with a Pavement Condition Index (PCI) rating of 70 or better, which means the surface is slightly oxidized from ...
Fog seals are used to delay weathering of the pavement, waterproof the pavement surface, improve the pavement's ability to keep water from penetrating the base course, reduce raveling and enrich weathered road surfaces. Sand Seal. A sand seal is a sprayed application of asphalt emulsion followed by a covering of clean sand or fine aggregate.
Sealcoat or pavement sealer is a coating for asphalt-based pavements. Sealcoating is marketed as a protective coating that extends the life of asphalt pavements. There is not any independent research that proves these claims. Sealcoating may also reduce the friction or anti-skid properties associated with the exposed aggregates in asphalt.
Fog seals are used extensively to maintain the quality of runways by rejuvenating porous friction course pavement and sealing the surface of smooth asphalt while preserving skid resistance. Fog seals are also utilized at times as a sealant over chip seals or new asphalt. In both applications they serve to seal the new surface as a preventative ...
Asphalt Institute also adds that fog seals can seal small cracks (3). 1.1 FUNCTION OF A FOG SEAL A fog seal is designed to coat, protect, and/or rejuvenate the existing asphalt binder. The addition of asphalt will also improve the waterproofing of the surface and reduce its aging susceptibility by lowering permeability to water and air.
Asphalt Pavement Treatments Fog Seal – "A light application of slow setting asphalt emulsion diluted with water and without the addition of any aggregate applied to the surface of a bituminous pavement. Fog seals are used to renew aged asphalt surfaces, seal small cracks and surface voids, or adjust the quality of binder in newly ...
