Ralumac – micro surfacing
Ralumac® Micro-Surfacing
Ralumac® micro-surfacing is a surface treatment f or preventive maintenance, rut filling and improving skid resistance on asphalt or concrete pavements. The Ralumac polymer asphalt emulsion, additives and aggregates are mixed and placed in a cont.
Pavement Preservation: Lower Costs, Higher Quality
The right tre atment on the right road.The Federal Highway Adm inistration issued a position statement in late 2004 that encourages street and highway agencies to extend their dollars by the judicious use of maintenance treatments. Many departments have found that costs are two to 10 times lower than rehabilitation, and that the preservation program results in a significantly higher overall quality road system.
The ideal maintenance treatment should be workable, cost effective, lower in raw materials usage and provide quick traffic return.For more than 25 years, Ralumac® micro-surfacing has been the right treatment for many pavements, from residential streets to high traffic interstates. A process continually improved by SemMaterials technologists, the Ralumac® system is a high performance, cost-effective surface treatment that preserves pavements and improves surface profile and skid resistance.
Ralumac components
• Polymer modified asphalt emulsion formulated for the process
• Materials selected for each location
> 100 percent crushed fine aggregate
> Mineral filler
> Additives as needed to control application process
• Laboratory mix design for each project
• Quick continuous mixing and application of ultrathin surface
• Rutfilling normally with two passes (rut box or scratch course and final surface)
Ralumac advantages
* Fills ruts, can be applied at varying thicknesses
* Restores texture, improves skid resistance
* Fast application (500 tons per day)
* Cures quickly for early traffic return (20-60 minutes)
* Nighttime or daytime application
* Ultrathin for maintaining overhead clearances, curb reveal and drainage
* Black surface
o Looks like hot mix surface
o Delineates pavement markings and shoulders
* Environmentally friendly cold process
* Cost effective preventive maintenance seals and protects pavement
Where should Ralumac micro-surfacing be used ?
• Structurally sound asphalt or concrete pavements with good drainage
• Very high to low volume roads
• Moderate severity surface distresses
> rutting
> raveling
> flushing
> polished
• Low severity cracking
• Oxidized surfaces
• Surfaces needing improved skid resistance
• Minor leveling
• May be used as an interlayer
A successful Ralumac micro-surfacing project can last from five to 12 years, depending on application and project location conditions. Ralumac micro-surfacing also is environmentally friendly; the cold application saves valuable energy and can be recycled at a later date.
