INDOT has fully implemented IRI for measuring highway smoothness on all QC/QA HMA & PCCP contracts. The 2023 construction season will be our first with full implementation of IRI utilizing high speed inertial profilers. The following RSP’s are now included in contracts when smoothness measurement is required: RSP 401-R-577 for HMA and RSP 501-R-752 for PCCP.
Recognizing that this is an emerging technology, INDOT will be offering an “Advanced IRI Pavement Smoothness for Construction” training course for contractors. This advanced training will be delivered by Brian Schleppi and Steve Karamihas. Schleppi is retired from the Ohio Department of Transportation and has decades of technical and field-based experience working with both DOT and contractor personnel on IRI equipment and software. Karamihas is a research area specialist at the University of Michigan Transportation Institute and has been involved in the research and development of IRI technology for decades and brings a wealth of knowledge and experience from his work in multiple states.
This “Advanced IRI Pavement Smoothness for Construction” course will cover the effective use of ProVAL by reviewing the following concepts: overall smoothness and payment utilizing the Ride Quality Module, areas of localized roughness utilizing the SAM Module, verifying equipment utilizing the Certification Module, verifying corrective work ahead of time utilizing the Grinding Simulation Module, and much much more.
This training course will be a single day event offered on two separate dates: May 24 and May 25 at INDOT’s Traffic Management Center (TMC) on the east side of Indianapolis. Training will be from 9:00 a.m. to 4:00 p.m. on both days. Cost for the training will be $180 per attendee. To register and make payment for this Advanced IRI training event, please contact our training vendor: Brian Schleppi at (614) 270-7001 or email@example.com.
INDOT and the training vendor require registration and payment be completed by May 11th. This Advanced IRI training requires each operator attending the course to bring a laptop computer and have the latest version of the ProVal software downloaded and installed.
This training is not mandatory and is not required as part of the requirements found in ITM 917 Section 7.1 in order to attend INDOT’s Annual IRI Certification day. All contractor personnel planning to attend this Advanced IRI training event should have already attended one of the mandatory training methods listed in ITM 917 Section 7.1 in order to have a baseline working knowledge of IRI concepts and IRI software use. However, for contractor operators that are re-certifying, this training course will count towards the ITM 917 Section 7.1 Triennial operator training requirement.
