Are Current Pavement and Road Maintenance Practices Suited for Cash-Strapped Communities?

Monday, June 21st, 2010

It is no secret that the recession has slashed the budget of many municipalities.  From a roadwork perspective, current practices and budget constraints mean government entities are delaying the maintenance of roads throughout their community and electing to rehabilitate when pavements have literally passed the breaking point.  Roads are a vital element of any community and their upkeep is not only important it is the key to creating savings within the system.

To the credit of today’s government entities, they are fiercely trying to do more with less and prioritize the use of funds based on absolute need. However sometimes this approach is not always effective.  For example, the timing assigned to pavement preservation strategies is pushed too far back to actually produce the results municipalities anticipate.   In fact, the longer they wait and the more deteriorated the roads are, the less effective the pavement preservation effort—no matter the approach.  From a financial perspective, this means that municipalities delaying maintenance in an effort to save in many cases are throwing money away because, for the most part, the life of a road (that has passed a certain level) can’t be extended effectively.

City Engineers and Public Works officials, accountable for the conditions of community roads, should take a step back and adjust the schedule, timing, and criteria for pavement preservation strategies to infuse overall savings into the system.  Furthermore, they should also examine new technologies that have entered the marketplace so they can potentially bring about savings as well as a modernization to their existing pavement management strategies.

Many of the municipalities that are struggling are the ones that are still applying pavement preservation and pavement maintenance efforts based on traditional and budget-based scheduling, timing and criteria.  The new administration’s stimulus package certainly helped jumpstart public work efforts across the U.S. and accelerate road maintenance activity.  However, according to recent evaluations of municipalities that have leveraged stimulus funds to implement pavement preservation practices within their communities, many did not consider scheduling, timing and criteria before implementing pavement preservation efforts and thus did not realize the full effectiveness of the practice.  See U.S. Dept. of Transportation for more information.

I understand many city engineers are being faced with the reality of short term financial constraints and politics, but consider that even impoverished nations/organizations (who often operate under even more limited budgets) have realized the need to make this paradigm shift and are better utilizing pavement preservation strategies.  More specifically:

  • The World Bank: International lending organizations and donor agencies like the World Bank currently provide loans and technical assistance to developing countries that are, like many local municipalities, operating under very tight budgets.  They fund public work projects including pavement preservation programs in order to extend the life of the investment made.
  • Cash-Strapped Country Initiatives: Many impoverished nations are conducting an assessment of their current network of roads and undergoing an optimal pavement preservation strategy (OPPS) review.  The goal is to delineate a pavement preservation programs that bring about longer-lasting roads throughout impoverished countries — roads are the key to economic progress.
  • International Road Federation: IRF invited field experts from 15 countries to discuss and share their experience with pavement preservation solutions (and its importance to the market).  The program was so popular they are repeating it again in August 2010 —this time featuring executive sessions analyzing different country experiences and lessons learned.

Necessity is the mother of invention, and being forced to work with limited budgets should be viewed as an opportunity to review existing processes and figure out a way to work smarter versus harder.  Municipalities that want to cut costs while serving their community effectively should recalibrate current pavement preservation strategies in order to adapt to this new cash-strapped environment we are in.  Organizations like the World Bank are leading the charge and helping to bring this paradigm shift to municipalities worldwide.  Perhaps you can lead the charge within the municipality you represent and ensure safe, long-lasting, and attractive roads and keep your community moving.

I welcome your thoughts so please feel free to comment.  In the meantime, I will put together a follow-up post with more specifics that illustrate how many organizations are doing this.  If you would like to receive notification of when this article is posted, please send me an email to nreck2010@gmail.com.

10 Things You Should Know About Preserving, Repairing and Resurfacing Roads (SERIES)

#1 Selecting the Right Pavement Preservation Products

The primary problem with pavement preservation is treating the pavement surface at the right time with the right product.   Sounds easy?  Well it isn’t!  One of the challenges is that due to reduced funding, agencies are forced to adopt a reactive approach to managing their road networks.  All municipalities want to protect their roads but budget cuts mean that the allure of the cheaper preservation materials are being put to the test on rehabilitation projects where the pavement has gone way past the 40% structural life – which is the sweet spot proposed by the pavement preservation association and the FHWA.

However, is something better than nothing?  It all depends on the product, but a few more important questions should be asked– why should I consider a pavement preservation product in the first place and what elements should I keep in mind when making a selection?   What should I watch out for when looking at products of multiple price points? Once purchased and implement, how can I maximize the performance of our pavement preservation treatment?

While the answer to all these questions would require an extensive conversation, below are some of the key elements to note when making this important decision.

Pavement Preservation – Remember, communities rely on easy and safe mobility on well-maintained roads.  Whether considering a highway or county road project, these infrastructures are costly to build, maintain, and rehabilitate.   Increasing the capacity of these tax-payer funded infrastructures is a fiscally responsible step that increases the value and life of roads as well as helps meet the important needs of the community.  Pavement preservation products can be the line item that saves money in the long run –talk to your contractor about them.

Surface Distress – It is not always the road traffic that prevents a pavement preservation product from performing at its highest level, but rather the degree and extent of surface distresses (such as reflective cracking) before the product is applied that impacts effectiveness.  When selecting a pavement preservation product, make sure its materials are specialized in addressing your existing surface distress.  By focusing on this element it will automatically help you narrow down the products relevant to your overall needs, help you create a short list of products that will extend the life of your roads by healing them with the right treatment, and help you compare apples-to-apples when conducting a price analysis.

Functional Distress – Surface distress (such as reflective cracking) is commonly found on all projects that are demarcated as ideal for maintenance and rehabilitation. However the functional distress of a road also needs to be considered.  Parking lots are great examples of this where untreated construction joints trigger water damage and then expedited structural deterioration.  So can the treatment address reflective cracking with interlayers?  Chip seals are now being used with paving fabrics!

Quality of Materials Used – Clearly there are countless low cost alternatives, however, these options are losing their glean in the current economy.  Municipalities are realizing that many low cost pavement preservation products result in greater costs to taxpayers – the roads have to be replaced and maintained more often than comparable roads that used a better product. Therefore, I say, let’s take advantage of the speed of installation and implementation of pavement preservation systems, but increase the quality of the materials that are being used.  This will not only extend the life of the roads built, but also help communities financially weather this unpredictable climate and environmental elements by reducing overall repair needs year-to-year.

New Road Resurfacing Innovations – I mentioned before that the chip seal surface treatment recently joined forces with a pavement fabric to tackle and mitigate the effects of the underlying cracks on the new surface treatment.   There are also new systems that can be installed together with stress absorbing and paving mat interlayers to achieve a durable surface treatment.  Other innovations have been developed as well but, when evaluating them, make sure they successfully treat the road without impacting performance and use controls to allow for a proper evaluation.  The right product should bring you both improved road network performance and reduced fiscal strain on your budget.

Clearly there are countless elements to consider when selecting a pavement preservation product, but the important thing it is that any road resurfacing and road repair project include it as part of its design.  Pavement preservation products can extend the life of roads, lower long-term road resurfacing and repair costs, and enables a community to continue operating and growing.  That should be the overall goal.  I look forward to hearing other people’s opinions.
