History

In 2016, the City of Gillette acquired the PAVER Pavement Management Software to aid in the evaluation and monitoring of the overall pavement condition within the corporate limits.  The Pertan Group was retained to perform the initial setup which included dividing the City streets into discrete sections and subsections based on pavement type, work history, and road classification. A ground survey was performed to identify the various types and degree of pavement distresses.  Once this information was entered into the software, analysis was run to calculate a Pavement Condition Index (PCI).  The software can be used to predict critical points in the pavement condition decline. 

In the fall of 2018, PERTAN performed condition surveys on the newly annexed streets in Antelope Valley and Crestview and updated pavement conditions elsewhere in town based on the work history since the 2016 survey.  The results indicated the overall pavement condition within Gillette had little change, declining only 1 PCI point.

Current Project

This project will include the resurvey of approximately 1/3 of the Gillette streets annually in the upcoming years.  A map is attached that illustrates the proposed survey zones.  Zone 1 will be resurveyed under this project this coming fall, including the streets west of Enzi and 4-J on the south side of Interstate 90 and Burma Avenue north of Interstate 90. 

The difference in PCI predicted from the 2016 survey and the upcoming 2019 survey will be used to "calibrate" the PAVER pavement model to the decline associated with Gillette's unique climate, pavement types, traffic, and other local variables.  This will allow for more accurate predictions of future pavement performance. 

Staffing

Pertan Group's lead PAVER Engineer has amiably separated from Pertan to start his own consulting firm, TR Consulting, LLC.  TR Consulting will bring existing knowledge of Gillette's street system, continuity in inspections and to the refinement of the Gillette pavement model.
