Why is pavement management important?
The nation’s road system represents an asset valued at more than $2.4 trillion. Nearly 90% of passenger-miles traveled and 60% of the nations’ total freight is transported via the nation’s highway system. There is no doubt, it is an asset worthy of substantial investment for the sake of our economy and the safety of our citizens.
Two constant elements unrelentingly diminish pavement’s value and cost the nation billions of dollars every year: traffic loads and environmental conditions.
A Public-Private Partnership (P3) is a contract vehicle where a private developer – working with a public entity – designs, builds, finances and operates the infrastructure. This Pillar Talk will focus on the rehabilitation, or handback portion, of a P3.
P3 transportation projects have two varieties: availability payment or revenue risk.
In an availability payment model, the public entity pays a fixed amount on a monthly or annual basis, usually after making some larger “milestone” payments during or at completion of construction. The funding could come from general transportation funds, a bond issue or indirectly from tolls generated from the new roadway but retained by the public entity or any combination of these. An availability payment P3 is generally of shorter duration, generally 25 years.
Last month I attended the 12th TRB Asset Management Conference (my third) and the 2018 AASHTO Committee On Maintenance Annual Meeting (my fifth).
While both conferences were about Asset Management, the focus of each was on two different planes. The TRB Conference focused more on strategic issues (i.e. risk, resiliency, sustainability) and the AASHTO Conference focused more on tactical issues (i.e. equipment, materials, technology, regulations). Asset Management has gone through a significant evolution from a tactical focus on operations and roadside maintenance to a powerful strategic management tool that enables agencies to better plan, manage and execute to maximize results and be more cost efficient.
John Meola, PILLAR's Safety Director, penned an article for the Richmond Times-Dispatch discussing safety rules motorist should be aware of as summer comes to an end.
Modern technology has catapulted maintenance of roadway infrastructure to a new level.
When it comes to collecting data about your assets, PILLAR utilizes the Leica Pegasus: Two Ultimate as its choice for mobile LiDAR. The laser scanning and mapping technology platform provides what we need to get the job done.
This device utilizes two back-to-back cameras to create 360-degree images from a vehicle, boat, 4-wheeler or train. A removable SSD means you have the information at your fingertips when you walk into the office.
