Summary
Reclaimed asphalt pavement (RAP) is added to virgin paving material at a 15% rate, reducing paving materials costs and avoiding landfill disposal costs.
Action
Rogers Group operates limestone quarries and produces aggregate and asphalt paving mix for the road building industry. In recent years the company has developed a new service and product by arranging to purchase used asphalt roadbed material from construction companies which specialize in the removal of old roadbeds. The reclaimed asphalt pavement (RAP) is trucked to a Rogers plant where it is crushed and blended with virgin material to produce a hot mix with approximately 15% RAP content, which is then reapplied as new roadbed. Because the material is very heavy, haul distance is a critical factor: Rogers has three plants in Indiana.
Payback
Rogers is able to purchase reusable pavement at a low price because it offers road construction companies an alternative to the high cost of disposing of the material in a construction/ demolition (C&D) debris landfill. Currently in Indiana markets, disposing of a 20-ton load of old pavement will cost upwards of $600 (at about $30 a ton). Rogers, in turn, reduces its own cost for extraction and processing of aggregates by substituting the reclaimed material for as much as 15% of new hot-mix, a competitive advantage. As part of its savings, Rogers avoids the cost of asphalt cement, a petroleum based material, for that portion of new pavement which is reclaimed material.
Additional benefit
By creating a market for old roadbed material, Rogers helps to reduce the illegal
dumping of old pavement.
