Cape seal is a treatment of chip seal followed by micro seal. It prevents water damage to the road bed and significantly extends the life of the road. The treatment cost for cape seal is $5 per square yard.
Crack seal is usually a first defense against pavement deterioration and is typically done to newer roads with small problem areas. Crack sealant is applied to cracks to prevent water and other materials from getting into cracks. Crack seal costs $2 per square yard to apply.
Granite seal (chip seal) is a surface treatment that puts a coating of asphalt oil followed by a layer of fine crushed rock over the existing pavement, which are embedded into the asphalt by a roller. Typically, graphite seal is used on low-volume roadways. Treatment cost is $1.84 per square yard.
We use a higher-quality asphalt oil and a finer aggregate made of granite. The resulting surface is smoother, has a sparkle, and looks more like traditional asphalt than the chip seals used by other local cities.
Micro seal is a mixture of fine aggregate, polymer-modified emulsion, mineral filler and water. Micro seal extends pavement life and provides a fast dry time to ensure the roadway is quickly usable. The treatment cost for micro seal is $3.20 per square yard.
Mill and overlay
A mill and overlay consists of milling off the top portion of the street and replacing approximately 2 inches of the surface. This technique extends the life of the road in a more cost-efficient manner than a complete reconstruction. The treatment cost for mill and overlay is $10 per square yard.
Reconstruction entails removing and replacing the existing roadway, curb and gutter, and performing any needed subgrade modifications. It is the most expensive of the rehabilitation methods, costing $50 per square yard.
Rejuvenators restore chemicals lost due to pavement oxidation and reduce the formation of additional cracks in the roadway. They are typically used on low-volume, low-speed roads and parking lots. Treatment cost is $1 per square yard.
Scrub seal is an application of diluted emulsion prior to the cape seal process. A scrub seal seals and fills voids and cracks in the roadway. The treatment cost for cape seal is $5.25 per square yard.
Slurry seal is a mixture of fine aggregate, emulsion, mineral filler and water. It is typically used to repair minor to moderate surface defects on roads. The treatment cost for slurry seal is $2 per square yard.
Ultra-thin bonded asphalt surface
Ultra-thin bonded asphalt surface (UBAS) is a preventative maintenance tool used to help extend the life of a road by placing a thin, coarse aggregate hot mix over a special asphalt membrane. The membrane prevents water leakage and provides a superior bond to the old asphalt. The overlay can disperse water quickly off the surface, which reduces roadway spray from vehicles and provides greater visibility in wet weather. UBAS can be installed quickly, and it lasts several years longer than microseal. Treatment cost is $4.85 per square yard.
