Pavement Preservation is a set of cost-effective treatments that are typically applied on pavements at their early stages and are relatively in good condition. Pavement Preservation allows transportation agencies to treat more lane miles with less cost, while lengthening the pavement’s service life. Transportation agencies adopting Pavement Preservation will extend the benefit of taxpayers’ dollars, among many other benefits.

Primary Benefits of Pavement Preservation

Transportation agencies are paying more attention to Pavement Preservation as their maintenance budgets get tighter each year. This led to the wide adoption of Pavement Preservation treatments within the agency’s operations and maintenance programs. Agencies adopting Pavement Preservation treatments record major benefits that include:

• Improves the condition of pavements and investments
• Remains cost-effective for service life and pavement performance
• Quick application and reduces road user costs and closure times
• Requires fewer resources and energy than reactive maintenance
• Stops the future deterioration of the pavement under your watch

Arguments Against Pavement Preservation Just Don’t Fly

Despite significant benefits, there are some reasons cities and towns don’t invest in pavement preservation as much as reactive maintenance tasks.

Civilians typically prefer all new pavement with new layers of either asphalt concrete or cement concrete. At the early stages of preservation treatment, pavement appears rough and messy until the treatments completely cure. To combat public outcry, engineers must continuously meet with civilians to educate them on the pavement preservation process. Engineers should demonstrate how reactive maintenance is more time-consuming and expensive, costing tax payers more money to fix damaged roads in the long run (see Figure 1).

The primary reason transportation agencies in cities and towns don’t invest in pavement preservation is due to a lack of expertise and knowledge on preservation treatments. With the variety of preservation treatments available, engineers don’t include the preservation treatments in their pavement management programs because they lack the know-how to choose the proper treatments for all road conditions.

Operations and maintenance professionals default to focusing only on damaged pavements, ignoring pavements that are in good condition. Asset management budgets get eaten up by reactive maintenance when they could invest in preserving good roads, therefore investing less in reactive maintenance over time.

Some have the misconception that preservation treatments are an unnecessary expense. In reality, the treatments are quick while costs stay at a minimum. Some agencies in rural areas fear that hiring contractors with pavement preservation expertise will be more costly than local professionals, however, including pavement preservation in pavement management programs will extend budgets and the service life of pavements.

Partnering with PILLAR Pavement Management Engineers

Sometimes an organization doesn’t invest in pavement preservation due to a lack of expertise. There is a certain complexity to managing a network of roadways at different stages in their lifecycle that requires insightful data and a guiding hand.

PILLAR can play a role in assessing needs and making important maintenance decisions.

For example, PILLAR uses ratings to assess the condition of pavements, watching as the condition rating changes with time. This can be helpful to maintain a standard while getting the expertise needed for these numerous treatments.

Choosing the Right Pavement Preservation Treatments

When choosing treatments, PILLAR helps you map out roads, traffic volumes, and regions to make sure that roads are treated in line with the best treatment. There is a wide variety of possible preservation treatments that make the care and maintenance of each road extremely unique.

Every preservation plan is unique based on the special features of the roadway and pavements that make planning your preservation techniques somewhat complicated without a competent partner. PILLAR works with you to identify the condition of the road or pavement and then develop a series of interventions to lengthen the lifecycle of the road, save time, and conserve budgets. Some noteworthy and famous pavement preservation treatments that can be used include:

• Crack Sealant
• Slurry Seal
• Chip Seal
• Cape Seal
• Microsurfacing (Latex)
• THMACO

PILLAR’s Dan Dennis, Vice President of Public-Private Partnerships was quoted on the positive trend of risk allocation in the P3 model.

If you are performing an outsourced O&M project, it is very likely you have a fixed budget based on your contract price. Your cash flow is known upfront, the day you sign the contract. As the Maintenance Manager, your job is to meet the contract performance requirements as efficiently as possible while meeting your budget. How do you do this? Simple: Spend resources wisely and efficiently. Basic planning can help you do this.

A typical example could be: The roadway shoulder has accumulated dirt, weeds, etc. in the longitudinal joints on a narrow shoulder next to a barrier wall. Simple enough to clean up, right? But the work area is three feet wide and adjacent to the left (high speed) lane on a 75-mph urban interstate. MOT requirements called for a full lane closure – in both directions.

What does this all mean? Before any work starts, you have already spent $2,800 for the two lane-closures. To save money and be efficient, how many other tasks can be done in that lane closure?

• Burn out the roots with a propane-hot lance torch.
• Seal the joints with hot or cold-pour asphalt joint sealer = no more weeds for five years.
• Jet-vac all the drop inlets within the lane closure.
• Install barrier-wall mounted delineators.
• Repair any potholes or crack-seal the longitudinal joint
• Sweep/vacuum the dust and debris.

These additional tasks will be required at some point. Why not do it all at once? The additional labor is minimal, and you likely have all the small tools; if not then rent them. By combining the activities, you have saved multiple lane closures and perhaps up to $10,000. This adds up.

This is basic preventive maintenance. And all it takes is – a little planning.

There have been numerous developments in recent years in the field of Artificial Intelligence (AI) that are transforming our daily lives. Among the most commonly recognized are self-driving vehicles and voice recognition devices such as Amazon’s Alexa.

While perhaps not as flashy as having your virtual personal assistant, Pillar Operations & Maintenance Advisors is a leader in the important integration of AI into the world of transportation asset management.

Using AI, Pillar can collect and assess vastly larger datasets in less time with fewer resources than ever before. What once took months to identify, collect and assess transportation assets can now take as little as three days.*

Why does this matter?

Pillar can help clients make cost-effective, data-driven transportation maintenance decisions and plans based on actual priorities derived from clear and comprehensive data. This data results in safer, better-maintained roadways for the traveling public.

For example, we gathered guardrail length inventory by assessing its condition in accordance to the Maintenance Rating Program for a state Department of Transportation. This data enabled the state DOT to develop a maintenance plan, allocate the workforce and secure a budget for the project.

Here’s a more in-depth look at how AI is being used in Pillar’s proprietary CAPE approach to transportation asset management:

Collection – We are using AI to help identify assets for gathering a database of inventory. To do this, we have trained algorithms that scan our imagery and point cloud data to locate assets. We also utilize a system that automatically extracts these features into a legible format. The two systems provide a level of redundancy and quality assurance that is integrated with your GIS. Together, these systems create a sophisticated level of detail that was previously unattainable.

Assessment – AI helps us assess the condition of transportation assets by using algorithms to identify items such as a leaning sign, clogged ditch, and much more.

Planning – AI is an extremely useful aid in conducting research. By combining “big data” with the inventory collection and assessment data, we developed algorithms to build predictive analytics that make proactive maintenance possible.

Execution – We use AI to monitor operations to ensure quality standards are met. Further, the data stays current as tasks and projects are completed.

*Timeliness will vary from project to project based on size and number of assets collected.

What is outsourcing?

Outsourcing is simply using contractors to do things traditionally done by in-house staff.

In the P3 space, virtually the entire project is outsourced, by definition. In a traditional, publicly owned and operated roadway, the Owner (DOT/Ministry, etc.) provides operations and maintenance for the roadway with in-house staff, trucks, equipment and materials. Similarly, a facility such as a hospital, manufacturing facility, port or other large fixed asset will have maintenance staff and operational support.

What are the benefits?

In a word, “Efficiency.” But how? For one, you get more efficient use of your people resources.

Good workers generally want to do a good job – finish it properly and move to the next task. Contractors and mechanics know this. If they have a lump-sum price to replace your HVAC system, they will get it done quickly and efficiently and move on to the next job. If you pay all of your subs a T&M rate, you won’t get this benefit. If all your maintenance personnel are hourly in-house staff, you are essentially paying them a T&M rate. They are not motivated to get the job done faster.

What’s so special about specialists?

With today’s technology and ever advancing and inter-related systems, it is much more difficult to hire, train and keep a “jack-of-all-trades” maintenance staff on hand. It is more efficient, safer, faster and cheaper to utilize a team of highly trained, on-call specialists. With new technologies on the horizon, you may not even need to “fly in” the technician.

Get better use of your equipment resources

• Don’t let it sit idle: If the machine sits in the yard most of the time, you don’t need to own it. Maybe it seemed to make sense when you bought it, but you are not in the business of amassing a fleet of equipment that sits most of the time. Instead, try subcontracting, renting or leasing it. Construction companies know this and have a fleet of lowboys working every night to get idle equipment to the site of a (paying) job.
• Paid-for equipment is not free: Maybe that motor grader sitting on your property is paid for. But if it’s not being used, that’s a $150,000 pile of cash sitting in your yard that could get another thousand feet of ditch cleaned or 200 potholes filled. At a minimum, share it or make it available to another location.

Finally, we mention profit. The profit motive drives efficiency and productivity. Although it can be a dirty word sometimes, the profit motive – coupled with performance standards – will undeniably drive innovation and ultimately result in lower costs.
