Abstract
A chipseal overlay coating having in situ deicing properties. An absorbent material such as lightweight aggregate, is mixed with oil, asphalt and/or concrete to form a thoroughfare chipseal overlay. Deicing materials are applied to the overlay or to the absorbent material prior to the mixing process. Due to the highly absorbent nature of the chipseal overlay, the deicing material is absorbed. During icing and snow conditions, the impregnated material reacts with the ice and snow to cause them to melt.
