EVALUATION OF POPCORN MIX SURFACE PERFORMANCE IN SASKATCHEWAN

Popcorn mix, as it is locally known, is a open-graded asphalt concrete mixture that is used as a surface course. The main concerns with popcorn mix are the effects it has on the road structure, the durability of the surface, and most importantly, maintenance problems in winter conditions. Voids account for about 25% of the popcorn mix. Salt and sand usage during winter, asphalt emulsion and asphalt mix usage during spring and summer maintenance can plug these voids, resulting in a loss of permeability. This report will evaluate the performance of the eastbound lanes of popcorn mix on the Regina By-Pass. The basis will be whether the mix provided a less hazardous travelling surface than the westbound lanes of dense graded hot mix. For the covering abstract of this conference, see IRRD number 872672.
