FHWA Offers Valuable Resources
- Monday, 09 July 2018 08:52
You probably have heard of the FHWA’s Mobile Concrete Trailer (MCT), and you may have had the opportunity to see it first-hand, but did you know how easy it is for contractors to borrow some of the MCT’s testing equipment?
To borrow equipment, contractors should contact Michael F. Praul, FHWA Senior Concrete Engineer (207.512.4917 | Michael.Praul@dot.gov) or Jagan Gudimettla, MCT Project Engineer, ATI, Inc. (202.366.1335 | Jagan.M.Gudimettla.CTR@dot.gov).
There are no forms to fill out and no excessive paperwork required, according to Mike Praul, who said if the equipment is available, it’s normally shipped within a couple days. He says there are no preset requirements for time the equipment may be borrowed. He adds one contractor “has had one of our super air meters (SAMs) for over a year.”
“All we ask is they take care of the equipment and return it as agreed,” he said, mentioning the contractors pay the return shipping costs. “When it’s time to return the item, we may ask you to return it to us or possibly to ship it directly to the next person borrowing the item.”
He said some flexible training options are available, too. “We are willing to provide training to industry personnel performing the test. The training can be over the phone or via video link or even phone/video calls,” he said. “Jagan and the technicians are well versed in the tests and do a great job training people to run them.”

CP Tech Center Releases RCA Publication
- Monday, 09 July 2018 05:35
“Using Recycled Concrete Aggregate in Pavement Base Products,” is the latest MAP* Brief released by the CP Tech Center.
The introduction describes how RCA is used widely as a base material, in part because its performance can meet or exceed that of natural aggregate. This 8-page document describes construction considerations, qualification testing, and pavement design considerations for both unbound and bound (or stabilized) RCA base. It also highlights environmental factors to look for, as well as well as related environmental benefits.
Written by Mark Snyder, Pavement Engineering and Research Consultants, LLC,** this MAP Brief also includes covers several example problems that provide some interesting and useful details, valuable information to agencies, consultants, and contractors working with RCA as a viable concrete pavement base.

Bob Steffes to Retire
- Monday, 02 July 2018 13:50
The CP Tech Center reports that Robert (Bob) Steffes will retire as Manager of the Portland Cement Concrete Research Lab (PCC Lab) at the end of July. During the past 15 years, he has guided ISU students and faculty through thousands of concrete tests, exams, and procedures at the PCC Lab. Steffes was an integral player in many concrete projects involving the CP Tech Center.
During his years in the PCC Lab, research activities have increased approximately ten-fold, ICPA reports. Bob said he’ll remember most, “The satisfaction from teaching and helping students in research operations and seeing them move forward with some of my mentoring. The many invitations I received from students I worked with, to attend their research defense presentations, for graduation. The challenging demands to be creative, and design and build unique equipment for multiple, unique research needs.”
Following retirement, he said he plans a move to Olathe, KS, to spend time with kids and grandkids.
ACPA joins with the CP Tech Center staff thanks Bob for his years of stellar service to the transportation community. For contact information, as well as other information about Bob, click here.
