Norris jumped at the chance to pur‐ chase the crushing plant. Overnight, Riverside was able to process recycled asphalt and concrete, two brand‐new markets for the little Wallace company. On top of that, Riverside was able to offer its services on the go; with the RDS‐15, it could provide customers on‐ site crushing services. It was ideal for companies that had several thousand tons of material that they wanted to keep but needed to crush. The timing couldn't have been any more perfect. Norris hadn't predicted it, but he made the purchase just before the econ‐ omy flipped, road improvement projects decreased and new construction slowed. On the other hand, the demand for re‐ claimed asphalt pavement (RAP) sky‐ rocketed because the residual liquid asphalt within the material (usually 3‐5 percent) makes the road building process more economical. In fact, because of a na‐ tionwide effort to stretch dollars and limit spending, the market saw a growth of 6.1 million tons in just one year, making a jump from 56 million tons in 2009 to 62.1 million tons in 2010. Riverside quickly gained asphalt and con‐ crete customers, and it wasn't long before its customer base had grown exponen‐ tially. Very quickly, the company's usual residential and commercial builders, as‐ phalt manufacturers and landscapers were taking advantage of Riverside's ex‐ panded offerings. In addition, by simple word of mouth among those in these industries, new cus‐ tomers learned of the new crushing com‐ pany and began requesting products and services. "We couldn't continue to put all of our eggs in one basket. If we had kept relying strictly on sand and gravel, I don't know that we would have survived," Norris said. "But expanding our services to include crushing concrete and asphalt gave us an‐ other avenue of income when the sand business was down." So as the recession sank in, Norris and the Riverside crew watched other com‐ panies dissolve in the downturn as they continued production across a broad‐ ened market. The New Impact at Riverside Buying the RDS‐15 closed‐circuit plant has made all the difference for both River‐ side and its expanding customer base. The RDS‐15's return conveyor cuts out the associated operating expenses and labor costs. For example, in a 10‐hour day, an em‐ ployee earns about $200. Add the cost of running, fueling, repairing and maintain‐ ing an additional piece of equipment, which averages about $100 per hour, and the total is roughly $7,200 in a six‐day workweek. The savings are substantial. The RDS‐15 took the lead role in as‐ phalt production because the plant pro‐ duces a consistent, cubical product sized to the necessary specs. For exam‐ ple, Riverside puts a 5/8‐in. screen on the bottom and a 1‐1/2‐in. screen on top and sets the machine to return the top two conveyors to the impact crusher to size the material. The out‐ come is 100 percent 5/8‐in.‐minus ma‐ terial and a 20 percent increase in production, which equates to greater production in less time, lower labor costs, less fuel consumption and lower operating expenses. Norris said asphalt has risen to the top of Riverside's production list and now accounts for about 60 percent of the business. The company crushes an aver‐ age of 950 tons of asphalt per day. Seeing things were going well, Norris decided to take it one step further. The unit had worked well, but it had been in operation for nearly two decades. Nor‐ ris had worked with the IROCK team on several occasions to ask questions and fulfill parts and service needs. He was always impressed with IROCK's sup‐ port, he said, so what came next was a natural progression. Hitting the Road Norris decided the used RDS‐15 would be best as a backup crusher and screening plant and Riverside would further excel with a new crusher on the front lines. During one of his calls with IROCK, Norris discussed purchasing a new unit. Sure enough, just three months after he pur‐ chased the used machine, he and IROCK closed the deal on a new RDS‐15. However, rather than using the new RDS‐ 15 on site as he suspected, the new unit became the company's traveling machine and the intended standby crusher re‐ mained stationary at the Riverside site. Riverside has been running both crush‐ ers steadily ever since.
