Los Angeles Street Irwindale, California 91706 Product Description: Basic Uses - To reseal the surface of a pavement to aid in preventing water penetration. - As a surface seal to fill minor cracks and depressions which can lead to a breakdown of the pavement structure. Limitations RoadGuard will not correct major alligator cracks or other deficient pavement conditions. RoadGuard's effectiveness will be limited if applied to pavement which has not been cleared of loose dirt andlor ravelled particles. And RoadGuard should never be applied to bituminous mixtures before they have had at minimum of 30 days to cure. Composition: RoadGuard is composed of fine mineral matter, fibers, clay, rubber and Type 1 Rockdust. Sizes: RoadGuard is available for purchase by the 55 -gallon drum or 5 -gallon buckets and may also be purchased for delivery in bulk, portable tanks. Color: The cured film is Deep Black. ITuesday Jut25 1995 10:41= -- Page 7 J1L.25 195 11:31AM 909-62G-3486 II DUSTRIHL ASPHALT DATA SHEET RoadGuard - Type 1 Rubber -Modified Road Slurry Technical Data: P.7 Specifications: The asphalt materials meet the requirements of ASTM D 977 for viscosity, residue by distillation, penetration and ductility. Drying Time: Ambient temperature dependent, though twenty-four hours is recommended. May take less time if ambient temperatures are high. Flammability: RoadGuard is non-flammable and will not flash or ignite. Asbestos -Free: RoadGuard contains no asbestos or other known carcinogens. Resistance: RoadGuard resists kerosene, gasoline, salt water and radiation. Installation: Surface Prep: - Clean and fill the cracks - Remove any saturated grease or oil from the pavement. - Repair any surface damage, then clean the surface of all dirt and loose or ravelled particles using a power broom, power blower or flushing with high pressure water. - For best results, the asphalt, just prior to being sealed, should be sprayed with a mist of water in an amount that will leave the surface damp but with no puddles or visible water. This is especially important when ambient temperatures are high or when the pavement is aged or porous. - For surfaces that have weathered excessively, priming may be necessary using a primer diluted with five parts clean water to one part SS -1h. Apply at a rate of one gallon per 100 square feet and allow to dry. If in doubt, a test patch should be applied. Tuesday Juty 25 1995 10:41= -- Pege 8 ]11.25 '95 11-'31AM 909--626-3486 INDUSTRIraL RSPHRLT P.8 DATA SHEET RoadGuard - Type 1 & Type 2 Rubber-Modfied Road Slurry - Never dilute RoadGuard. Must mist ahead of machine or truck. - To insure a proper bond, the minimum ambient temperature should be 55 degrees Fahrenheit and rising. Minimum surface temperature should be 60 degrees Fahrenheit. -For best results, RoadGuard should be applied and cured during dry weather. The following chart provides a guideline for approximate coverage. However, please note that these are guidelines only and exact coverage depends upon both the condition of the existing pavement and the surface application rate specified: Smooth, dense pavement - 40 gals per 1,000 sq. ft. Medium surface - 45-50 gals per 1,000 sq. ft. Rough, aged surface - 55-60 gals per 1,000 sq. ft Excess, rough surface - 65-70 gals per 1,000 sq. ft.
