Asphalt Road Recyclers Have to Be Seen to Be Believed

These powerful machines actually grind up existing asphalt roads, reheat the asphalt and spit out reconstituted asphalt that's road ready.renova asphalt recycler

When a friend told me about a video he had seen about asphalt recyclers, I figured he must have the story wrong. Sure, there are machines that pulverize C&D debris, machines that make cement, keep asphalt hot and ready, but an asphalt recycler? Wishful thinking.

Or not. It turns out that these machines do in fact exist, and they accomplish the seemingly impossible task of turning old roads into useable material.

One of the more advanced models, the Renova 4000, can produce up to 10 tons of hot mix per hour. Of course, in terms of repaving an entire road a 4 inches of depth, that's a relatively small quantity, but the company notes that the product is ideal for creating patch-sized batches.Here's the product writeup:

RENOVA’s batch process permits flexibility to travel to repair site with 2 tons of mix, reheat mix when needed, check mix temperature at any time, discharge directly into front-end loader or into a waiting application, adjust additives, and dry out wet millings.  Time length of 2-ton batches varies by conditions and state of millings, can be 12-20 minutes with capability of 8 to 10 tons/hour production. The RENOVA is appropriate for patching potholes, utility cuts and other small asphalt repairs year round regardless of the outside temperature. The savings realized pay for the machine quickly as you recycle old pavement instead of buying replacement hot mix from the asphalt plant. 

Another brand, the KMT-2 has similar characteristics.

 These diesel-powered machines offer a potential game changer, allowing contractors to reuse road material. The "secret sauce" is a proprietary mix of polymers including rubber that are added to the asphalt to give it shape, adhesion and consistency.
