ABSTRACT:
Diatomite-modified membrane and slurry seal mixes having improved properties. An impermeable membrane suitable for protecting cement bridge decks and roadways has from 9 to 14% by weight asphalt, 0.5 to 3.0% diatomite with a preferred diatomite/asphalt ratio in the range of 0.08 to 0.30, with the balance being fine aggregate (sand). This membrane can be placed by conventional paving equipment, can withstand temporary traffic loading prior to installation of a wearing course, can be preformulated in sheets, and is a crack resistant (i.e., self-healing) under normal traffic loads. Also disclosed is a slurry seal cold mix with improved abrasion resistance, adhesion/cohesion, and tensile strength. With these improved characteristics, slurry seals can be useful as bridge deck and roadway membranes in addition to its standard overlay uses.
