Modified: The application involves a self-priming paver, which applies an emulsion bond coat directly in front of the paving screed where an ultra-thin overlay of hot mix asphalt is placed. Type A: 1/4" maximum aggregate size mix. Type B: 3/8" maximum aggregate size mix. Type C: 1/2" maximum aggregate size mix. When Appropriate when a new hot mix wearing course is needed. Ideal for roads with no structural improvement required. When there are issues with friction or pavement slip at intersections or on hills. Why Provides the durability of hot mix with a much stronger bond than traditional tack coats. Improves rideability, allows for minor adjustment of cross slope and elevation, and results in minimal loss of curb reveal. Results in a higher friction wearing course than traditional hot mix and eliminates hydroplaning. Watch Video FiberMat® What Type A: A combination of polymer-modified asphalt emulsion, chopped glass fiber strands, and aggregate as a fiber-reinforced stress absorbing surface course. Type B: A combination of polymer-modified asphalt emulsion, chopped glass fiber strands, and aggregate as a fiber-reinforced Stress Absorbing Membrane Interlayer (SAMI). When For use when it becomes necessary to absorb movements in poor pavement surface structure and prevent the pavement from cracking further. To correct raveling and oxidation issues of existing pavements in good condition. When used as an interlayer, to enhance performance of top wearing course. Why Stretches maintenance dollars by repairing and significantly delaying cracking. Prevents water intrusion. Enhances the tensile strength and fatigue performance by 30%. Watch Video ‍ Microsurfacing & Slurry Seal What Microsurfacing: A treatment, placed on a continuous basis, that consists of applying a proportioned mixture of polymer modified asphalt emulsion, aggregate, mineral filler, fiberglass strands, water and other additives to a paved surface in a single lift. Slurry Seal: A treatment, placed on a continuous basis, that consists of applying a proportioned mixture of asphalt emulsion, aggregate, mineral filler fiberglass strands, and water to a paved surface in a single lift When For roads that exhibit low severity cracking, raveling, and oxidation. Ideal for sealing and filling voids in the existing surface while improving skid numbers. Used for correcting mild rutting without additional crowning or surface buildup. Why Maintains minimal change to pavement elevation and curb reveal. Offers superior adhesion to existing pavements. Highly skid resistant. Watch Video Chip Seal What Single Chip Seal: A thin preventive maintenance overlay consisting of a heavy spray application of asphalt emulsion followed by a single layer of clean, uniform sized crushed stone. Double Chip Seal: Two layers of single chip seal applied one immediately after another. When When necessary to provide a skid resistant wearing course with a minimal change to pavement elevation. For roadways showing early signs of deterioration with low severity cracking, raveling, or rutting. To correct oxidation issues of existing pavements in good condition. Why Seals the pavement from intrusion of water and reduces oxidation and weathering of the surface. Most cost-effective method to address raveling, correct bleeding and flushing problems, improve skid resistance, and generally extend the pavement life. Double seals provide a strong solution for a distressed pavement in lieu of removing and replacing. Watch Video Cape Seal What A two-part process consisting of a chip seal followed by a microsurfacing or slurry seal wearing course. When May be used on pavements that are too deteriorated to use a chip seal, microsurfacing, or a slurry seal alone. When low severity cracking and minor wheel rutting are present, even in heavy traffic areas. Ideal in locations where a double surface treatment is needed, but loose stone is unacceptable. Why Cracks are sealed, drastically reducing the intrusion of water into the pavement structure. With the addition of the top treatment, a slurry seal or microsurfacing, the road ends up with a smooth surface that binds any loose aggregate, reducing stone loss. Addressing both preventative maintenance and rehabilitation needs, cape seals combine the benefits of both a microsurfacing/slurry surfacing system and a chip seal, which enables them to provide more protection and durability as compared to that of other preventative measures alone. Crack Seal What A preventative maintenance treatment that uses high quality rubberized material to increases pavement life at a minimal cost by keeping water out of cracks and penetrating pavement structure. When For roads showing early signs of deterioration For use on roads that are in good structural condition but exhibit single, well-defined cracks For preparing roads prior to new surface treatments Why Increases pavement life at a minimal cost Prevents water intrusion, sub-surface ice formation, and structural failure of roadway Reduces formation of secondary cracking, rutting, and pothole formation Watch Video Mastic Crack Seal What Hot applied pourable, aggregate-filled, flexible, self-adhesive patching material. Used for maintenance and repair of asphalt and concrete pavements. When Distresses that are too large for crack sealing but too small for complete road reconstruction. Wide cracks, longitudinal and transverse cracks. Potholes, Joint Failures, Bridge Decks, Manhole leveling. Why Flexible, Durable, Highly adhesive . Best option for treatments too extensive for crack sealing. Waterproof and voidless repair. Fog Seal What An inexpensive, cost effective pavement preservation treatment where a light application of diluted emulsion is applied to pavement surfaces which slows caused by environmental factors such as sunlight and thermal variations. When For use on pavements that are oxidized and in need of rejuvenation. Ideal for sealing a new chip seal, FiberMat®, CIPR, or cold mix paving project. Recommended as a pretreatment for porous surfaces that need to be prepared for an overlay. Why Fog sealed surfaces will add aesthetics, alleviate raveling, and seal minor cracks. Fog sealing promotes adhesion as a pretreatment on all pavements. Slows the deterioration of pavement surfaces caused by environmental factors such as sunlight and thermal variations. Cold Mix Paving What A mixture of aggregates and emulsion, blended and placed in one continuous operation using a mix paver or pugmill blended on site then placed in a conventional paver. When Ideal when a flexible pavement is needed for substandard sub-bases. To be used as an economical option for a shim paving course prior to a wearing course. For older roads that need rebuilding from the sub-base up. Why Crack and rut resistant. Strength is comparable to hot mix asphalt. Durability and flexibility exceed that of conventional hot mix asphalt. Watch Video Facilities Preservation Recycling Materials Careers Contact © The Gorman Group, LLC.
