Proper maintenance of asphalt driveways, parking lots and roadways is a critical aspect to providing good performance over an extended period of time. There are many commercially available grades and types of asphalt emulsion-based sealers designed to extend the service life of these surfaces. ADMIXUS® fibrillated HDPE fiber has been shown to significantly improve the properties of these commercially available coatings. Through proper suspension of pigments and fillers, reduced cracking, increased flexibility and reduced shrinkage, overall coating performance can be greatly improved.
The study discussed in this article examined the quality of film formation, tensile properties and wet track abrasion resistance. For this experiment, a commercially available, entry-level asphalt emulsion-based sealer was purchased, and the properties were tested with and without the post addition of various grades of fibrillated HDPE at three different dosage levels.
