Verglimit Deicing Chemical Asphalt Additive, SR 309- 02M, Lehigh County. Construction Report
In 1988, the Pennsylvania Department of Transportation (PennDOT) constructed an ice retardant bituminous concrete overlay on SR 309, Section 02M in Lehigh County. The chemical additive Verglimit was added to the bituminous concrete mix at a rate of five percent of the total mix weight to produce the ice retardant mix. Only minor mix design and construction modifications were necessary to produce the ice retardant mix. The asphalt content of the Verglimit modified mix was increased by 0.1 percent as compared to the control mix of a standard ID-2 wearing course. Although post construction bleeding of the pavement was noticed, skid tests performed five and eight days after construction indicated that the overlay had adequate friction resistance. The performance of the Verglimit overlay has been identical to that of the standard mix ID-2 overlay placed on the project.
