Reduces Asphalt Failures in Road Building

Applied to aggregate roads just prior to paving with asphalt, Earthbind® Prime acts as a moisture barrior between the aggregate base and the asphalt layer. In addition it binds the two products together, to keep them from separating. Earthbind® Prime eliminates this failure.

Earthbind-100 and Earthbind® Stabilizer are used together as a bituminous based prime coat. As a prime, Earthbind® can be applied onto a surface or mixed into the uppermost portion of a compacted granular base before the application of an asphalt surface treatment.

Both Earthbind® 100 and Earthbind® Stabilizer are biopolymer modified asphalt emulsions. The chemistries of Earthbind® allow for exceptional aggregate penetration, waterproofing, and adhesion to asphalt overlays. In addition, Earthbind® works especially well on granular bases with excessive fines.

As a prime coat, Earthbind® can:

  • Help seal the surface pores of a granular base therefore resisting moisture from migrating into and out of the base;
  • Strengthen the surface of a granular base by binding aggregates together;
  • Protect the base during inclement weather;
  • Mitigate fugitive dust;
  • Protect the base from limited traffic prior to pavement; and
  • Promote adhesion between a granular base and the asphalt surface treatment.


When compared to other prime coats:

MC-30 as a prime is an asphalt cutback that is formulated with an organic solvent used as a “cutter”. The organic solvent is not considered to be environmentally-friendly. In contrast, Earthbind® does not contain any organic solvents. Earthbind® is considered to be environmentally-friendly.

MC-30 due to the organic solvent has a longer curing time when compared to Earthbind® MC-30 usually requires at least 3-days to cure whereas Earthbind® can cure in as little as several hours.

Traditional asphalt emulsions (e.g., SS-1, CSS-1, etc.) do not work well as a prime on an aggregate base with fine particles. The fine dust particles greatly inhibit penetration. In contrast due to its unique formulation, Earthbind® penetrates fine particles very well.

Traditional asphalt emulsions are either cationic (CSS-1) or anionic (SS-1).
Anionic emulsions used as a prime are specific for aggregates with an overall positive charge (e.g., limestone) whereas cationic emulsions are used on aggregates with a negative charge (e.g., granite). In contrast, Earthbind® is non-ionic and can be used on both positive and negative charged aggregates.

Petroleum resin prime cures may be formulated with materials that are traditionally used as lubricating oils. These petroleum resins may not adhere to an asphalt overlay as well as primes that are formulated with asphaltenes due to differing chemistry. Earthbind® u2019s unique formulation ensures that there will be a good bond between the treated granular base surface and an asphalt surface treatment. Earthbind® u2019s chemistry will greatly reduce the likelihood of delamination between the base and asphalt surface treatment.
