In Tips with Todd, RoadBotics Product Manager Todd Saulle shows you how to use specific tools within RoadWay, and how they could be useful to your public works department or engineering firm.

Users with Individual Distress Identification (IDI) on RoadWay can isolate a specific distress and view its prevalence and severity in the point-level data. 

Let’s learn the best practices for isolating individual distresses. 

How to Isolate a Distress

To begin, open your IDI assessment on RoadWay, and select a point on the map.

Above the road image and conditional rating, you’ll find the ‘Isolate Distresses’ function.

Select the distress that you are interested in assessing, then hit the ‘Play’ or ‘Next’ buttons.

Along that segment, RoadWay will show only the data points containing the distress you selected. Note: The point level data may also contain other distresses in addition to the one you’ve isolated.

Isolate a Distress by Conditional Rating

RoadWay is a robust platform for viewing and analyzing road network data. In addition to isolating a distress across the entire network, you can also understand the prevalence of that distress at different severity levels by filtering conditional ratings. 

To do this, expand the left side collapsible menu and toggle to look at point level data at different ratings. Then, isolate the distress as outlined above.

Let’s look at two applications for isolating individual distresses by conditional rating – tackling ‘worst first’ and using the data to develop a long-term pavement management plan.

Worst First

Tackling the worst roads first is a common approach to infrastructure asset management. However, repaving an entire road is a costly endeavor. Isolating the worst instances of a particular distress allows you to decide which rehabilitative approach is best based on its prevalence, severity, and scope.

Let’s use fatigue cracking as an example.

To find the worst instances of fatigue cracking in your road network, toggle to select the point level data rated a 5. Then select a point on the map and isolate the fatigue cracking distress.

The stretch of road in the clip will require repavement because of the widespread severe fatigue cracking.

Long Term Pavement Management

Although the worst first approach may seem the most logical, often it is beneficial to develop a long-term pavement management strategy to save resources over time. 

Roads that are rated a 2, 3, or even 4 are good candidates for preventative maintenance because the visible distresses are mild to moderate. Minor rehabilitation will prolong the life of the pavement by ensuring the distresses do not quickly progress to failure. 

Let’s isolate transverse/longitudinal cracking and filter point level data to display 2s and 3s.

As you can see in the clip, the transverse/longitudinal cracking is minor and can best be addressed by a crack seal plan. 

IDI is a useful tool for developing pavement management strategies based on the prevalence and severity of distresses.

Tip: Take screenshots from RoadWay to include in your plan so field crews are better prepared for the rehabilitative measure.
