Back in 1997-1998, I worked for T.L. James Construction. They sent me to Pine Bluff, AR to work as a concrete QC tech on the stretch from US 79 to US 63. The part from US 79 to Old Warren Road was paved with a 7" base of econocrete & 11" of concrete. The stretch from Old Warren to US 63 was paved with 18" of concrete put down on a base of oil-soaked dirt.
Econocrete is a mixture of SB2, sand, & portland cement. The numbers for the crushing criteria were low...IIRC 500#s. I think it was a creation of T.L. James, but I'm not sure. They claimed it was supposed to give the road a 50-year life. I was wondering if Arkansas ever used econocrete anywhere else? Also, how is that road holding up? I haven't seen that road in many years.

According to Google, maybe AR 54.
