Arizona Rock Products Association
The Arizona Rock Products Association (ARPA) is a trade association representing companies producing nearly all the aggregate materials in the State of Arizona. ARPA’s members include producers or suppliers of aggregate, concrete, ready mix asphalt and cement; trucking firms, paving contractors and other aggregate end users; material testing labs; and ancillary companies.
Seidman has produced several economic impact analyses for the ARPA using an IMPLAN model. The results of a 2018 study are posted on the ARPA website, and were presented at the Association’s annual conference.
