We have recently received questions regarding why we are doing a oily sand mix on various City streets. The product is called Reclamite and the following information may answer your questions.
Reclamite is a product which can rejuvenate the oily, resinous component of asphalt which has been lost from the asphalt cement binder due to the natural process of oxidation. It is applied using a tanker truck that sprays the product on the asphalt like chip seal binder. Once the product has cured, 15-45 minutes depending on weather conditions, the lane will be reopened to traffic.
Reclamite plays a similar role as a chip seal in that it prevents water from penetrating into the asphalt by sealing the surface. It also helps rejuvenate the asphalt by restoring maltenes that have been lost from the oxidation process. Oxidation and UV damage are reason why an asphalt street turns from black to brown to an almost gray color as it ages
Reclamite will extend the life of asphalt to provide an extra 5-7 years before another seal coat is needed.
There is a significant cost savings with using this product over the traditional mill and overlay. The Reclamite product normally cost between $0.85-$0.98 a square yard to apply ($0.94 this year) while a mill and overlay cost $10.75 – 11.50 per square yard.
We have tested Reclamite on some City streets for a few years with good results.
