Promoting the Film Formation and Flexibility of an Asphalt Emulsion Sealer with the Addition of Fibrillated HDPE - MiniFiber

As a follow-up study to a previously reported increase in film flexibility, the film formation at temperatures from 45 to 115°F of films of an asphalt emulsion based driveway sealer with and without the post-addition of fibrillated high-density polyethylene fiber has been investigated. Utilizing six different grades of synthetic fiber, the nominal diameter and the nominal length of the fiber varied from 5 to 15 microns and from 100 to 900 microns, respectively. The resulting propensity of film formation has been shown to generally increase with fiber size; small fiber promoting less film formation than medium or large fiber. In addition, the resulting film formation has been shown to generally increase with fiber application rate; an increasing film forming trend from 0.5% to 1% to 2% fiber. Furthermore, a strong correlation between film formation and the ultimate elongation of the film has been observed.
