Make us your first choice.
Idaho Asphalt Supply Inc. (IAS) was founded in 1976 by John and Roxine Stone, and is now a second-generation family business supplying materials to the highway construction industry. IAS supplies materials and services that improve pavements without compromising safety or the environment. IAS strives to provide a higher quality of life for our communities by increasing pavement performance; and to work in partnership with government agencies, contractors, and suppliers to maintain better roads, parking lots, highways, and runways in the markets we serve.
In 2004, IAS began its first wave of expansion into new markets by acquiring two of its current facilities in Utah and Wyoming, operating as Peak Asphalt LLC.With that purchase, Idaho Asphalt established itself as the leading supplier in an eight-state region. In 2016, the company acquired Western Emulsions Inc. with six emulsion plants and a liquid asphalt terminal.
The company’s administrative offices are located in Idaho Falls, Idaho where our transportation company, Johnny B. Transport LLC is based. Johnny B Transport is among the largest in-house asphalt transportation companies in its market, with full service capabilities and assets including asphalt tankers, asphalt spreaders, railcars, and portable pumping units.
First Choice. These two simple words are at the heart of our company’s mission, and a foundation for our corporate philosophy. We will become and remain the first choice of our customers, workforce and suppliers by:o Striving to be the preferred producer of asphalt and emulsion products in the markets we serve. o Nurturing mutually beneficial relationships with suppliers who help us manufacture the best products the industry has to offer. o Cultivating a dedicated team of professionals who excel in their roles and, in turn, attract and recruit the best talent to lead our team forward. Our company’s culture is built on hard work, a customer focus, and a pursuit of continuous improvement. Rather than concentrate on short-term gains, we prefer to generate long-term value for the benefit of our customers, employees, suppliers and communities.
