EXPERT ADVICE Continued from page 24 colder climates with freeze-thaw issues. Generally, the paved asphalt surface is heated to soften it before a metal grid with the brick or stone paver pattern is applied with force to create the look. An infrared panel can heat existing pavement to 30 times the temperature of new asphalt to soften it and make it easier for imprinting or stamping. “Be patient when imprinting or stamp- ing, since fixing a mistake can be very ex- pensive,” Strassman said. “If the grid pattern gets off kilter, the rework can eat up the profit margin on a job. You need to make sure the grid pattern matches up perfectly -- we recommend overlapping the grid during the application process to ensure the consis- tency and accuracy you want.” Achieving the look of a historic brick- paved or cobblestone road can be achieved faster and easier than laying individual pav- ing bricks or placing the cobblestone. It helps to meet commercial and municipal needs for decorative pavement that is dura- ble, economical and maintainable. Imprint- ed or stamped pavement is used around the world in all types of climates. It is unaffected by road salt and does not tend to absorb oil. Virtually invisible repairs can be made to cracks, tree root problems, settling after new building construction or mechanical damage. No annual mainte- nance is required; just the proper installation of a base of high quality asphalt pavement. Specifically, the process of imprinting or stamping asphalt begins with the pattern. Steel or woven wire templates are pre- formed into the desired design. The tem- plates are laid out on the hot or reheated asphalt surface, which is at 170°F. Once in place, a vibrating plate compac- tor is then placed across the pattern. After compaction, the templates are removed and an even 3/8” imprint is left in the asphalt surface, creating a uniform, seamless pat- tern. After the stamping process, an acrylic based paint coating is applied via roller or spray adding color.

These include reduction of surface temperatures (cool pavement) to reduce urban island heat, the aesthetic value that color brings to pavement, and provid- ing vehicle and pedestrian flow through col- or-coded pavement areas such as bus lanes, bike lanes, walking paths, taxi/Uber/Lyft pick-up stands, and handicap parking to name a few. Color can be achieved through an acryl- ic colorized asphalt pavement sealer which has been used for color coating parking lots, driveways, bus lanes, bike lanes and more. “Our color system has been very popular for creating safe, non-slip areas in dry and wet conditions,” stated Jeff Gearheart, di- rector of SportMaster Sport Surfaces, Thor- Works Industries, Sandusky, Ohio. “Many times, the decorative pavement sites are the focus areas at special events or businesses.” Gearheart continued: “Lighter colors are in demand, and not only do they draw at- tention to the area, but they lower the pave- ment temperatures for increased comfort.
