Pavement Preservation Techniques | Emulsion Services

pavement-preservation-bci-asphalt-plant Our emulsion services include providing pavement preservation products, such as fog seal emulsions, chip seal emulsions, and the formulation and design of slurry seal emulsions and micro surfacing emulsions. For properly selected projects, pavement preservation products and techniques can renew existing roadway surfaces at a fraction of the cost of traditional “mill and fill” repaving operations, thereby helping transportation agencies stretch their maintenance budget dollars.

The graph below illustrates various pavement preservation techniques that can be selected to renew pavements based on where a pavement is in its service life and its existing condition. To learn more about these pavement preservation techniques and when to use them, place your cursor over each technique shown on the graph.

Pavement Preservation succeeds when you select the right treatment for the right road at the right time.

Fog Seal

The application of an emulsion typically reduced with water to a 1:1 ratio to refresh an existing pavement surface, or applied on top of a chip seal surface treatment. For existing pavement surfaces, it can be performed at 85% to 95% of pavement condition.

pavement sealer

A quality rejuvenating pavement sealer like GSB-88® can not only reseal the pavement surface, but also rejuvenate the existing asphalt surface to help reverse the effects of oxidation. Perform this surface treatment at 80% to 95% of pavement condition.

chip seal

A surface application of emulsion (latex modified emulsion is best), followed directly by the application of aggregate “chips” and then rolled to seat and align the aggregate into a new higher friction wearing surface. Best when performed above 70% of pavement condition where surface cracking is minimal.

microsurfacing

An environmentally friendly cost effective cold mix system that creates a new stable and skid resistant surface that is resistant to rutting and shoving, and works great for wheel path rut filling (rut depth not exceeding 1.5 inches) prior to full width overlay. Perform micro surfacing at 60% to 75% of pavement condition where surface cracking is minimal to somewhat moderate.

thin lift hot mix overlay

A thin lift overlay of 4.75 mm hot mix asphalt placed over a prepared surface after rut filling, micro milling or crack filling operations. Performed at 60% to 75% of pavement condition.

cape seal

A combination of two techniques, chip seal followed by micro surfacing, this treatment is effective for road surfaces with minimal to moderate surface cracking. Apply cape seals at 55% to 75% of pavement condition after full depth patching of any areas exhibiting questionable pavement distress.

full depth reclamation

Cost effective and environmentally friendly project site recycling of the full pavement section and a predetermined portion of the underlying materials to yield a stabilized base course ready for new wearing course pavement. Use when pavement condition is poor and in need of major reconstruction.

recyflex

Innovative engineered base material that contains recycled materials and is a flexible pavement structure as compared to rigid cement treated base (CTB) structures. RECYFLEX® also has a higher structural number than traditional 25mm Superpave base courses, yielding savings in new HMA costs in heavy structure roadway reconstruction and new roadway construction projects.
