FEATURE
• Leveling of the asphalt surface where dips and divots are present
• Binding speed bumps to existing asphalt surfaces ( roads , parking lots , etc .)
• Creating patterns in the asphalt for aesthetic purposes or rumble strips on highways Infrared asphalt repair is useful in a wide variety of applications .
There are even different applications that most would not think of using infrared , but have proven to be very effective . “ Riser installation is ideally suited to IR ,” Martin said . “ Whether it ’ s for installing risers to manholes , catch basins or gate boxes , the infrared process is far and away the best method for doing this . By just installing a riser to the inside of the frame or gate box you can adjust the height of the utility in just 15-20 minutes . This not only prevents traffic from dropping into a basin or manhole that sits too deep , but it also prevents the structure from getting broken down over time due to the constant weight load of vehicles and especially heavy equipment during snowplow season . Risers come typically in 3 sizes 1- , 1.5- and 2-inch and can be stacked on one another if needed .” Infrared repair solutions can vary . “ Let me give you two atypical applications ,” Blake said . “ First , is thermoplastic installation . Thermoplastics are becoming a popular alternative to standard line-striping paint . Right now , most contractors are just using a torch to install those thermoplastic templates which takes forever and is an uneven heat . With an IR machine , those thermoplastics can be installed in a couple of minutes . “ The second application , is repairing paving mistakes on a new pavement install . As much as contractors hate to admit it , mistakes like roller marks , cold seams , high / low spots happen occasionally on new paving projects . If one of these do occur , a standard practice is to just take a torch to heat the area up , rework it if needed , and then roll it again , which again can be a bit time consuming and the torch is an uneven heat . With an IR machine those paving mistakes can be handled in a couple of minutes and completely blend in with the new pavement .” Infrared repairs are often the go-to solution for asphalt pavement issues . Martin described how effective IR is with pothole repairs , “ Infrared can repair all types of potholes even if the subbase is exposed . On deep potholes , the best practice is to patch-in these areas first and then compact to assure repair does not sink on you when doing the infrared repair . It also doesn ’ t hurt to add a tack coat to any of the potholes you patch before heating . This helps assure a bond around the potholed area .” Even though infrared waves cannot be seen , the results from its use for the asphalt paving contractor can be quite dramatic , productive , and profitable .
