Van Trip Participants

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.
