UDOT CPR Van Trip
Sponsored by Utah Chapter, ACPA and Multiple Concrete Enterprises
What do get when you add a van full of UDOT folks, blue sky, and a few
bags of candy? One heck of a CPR van trip! On October 18th, representatives
from 3 of the 4 UDOT regions, as well as the concrete engineer for the
state, joined the Utah Chapter, ACPA and Multiple Concrete Enterprises
for an outing to the Idaho/Utah border to take a look at the dowel bar
retrofit/diamond grind project on I-15. This $6.5 million project consists
of 16+ miles of CPR, including diamond grinding, DBR, and full depth repairs.
The original section of pavement was constructed in 1976 with 8” of PCCP
over 4 inches of CTB. It was a great day for all, including the consultants
on the project who came over from Boise and Pocatello to give a bit of
background on the project.
Region 3 currently has a few projects in mind along I-15 that would be
suitable candidates for DBR/DG. Region 1 has a project that is perfect
for DBR/DG along 84, and there are several potential projects in Region
2. After seeing the work completed in Idaho, the Regions are confident
that dowel bar retrofit combined with diamond grinding is a worthwhile
investment for aging undoweled concrete pavements in Utah.
