Pavement Maintenance – Prevention or Repair?

The phrase “pavement maintenance” can mean a lot of things, ranging from simple cleaning or restriping up to fixing severe distresses like potholes and washouts. Maintenance can also involve different approaches, based on whether the emphasis is on repairing distresses or preventing them before they happen. We’ll explore the essential concept of pavement maintenance and the different types of activities that fit under this umbrella.

Maintenance Work and Pavement Life

One goal all maintenance activities have in common is extending the life of the pavement. Pavements are increasingly being designed for longer service lives, and longer-lasting pavements mean more opportunity for maintenance over the life of the pavement structure. To demonstrate the value of a long life pavement, it needs to show a lower life cycle cost than traditional alternatives, factoring in both the initial construction cost and ongoing maintenance over its functional life. In this approach, keeping pavement maintenance costs down is helpful to the success and viability of the design. That doesn’t necessarily mean that maintenance should be less frequent, but the maintenance activities must be cost-effective.

An important aspect for cost-effective maintenance over the pavement life cycle is the selection and timing of maintenance activities. Using the right maintenance treatment at the right time will help you get the maximum benefit. This depends partly on the condition of the pavement and where it is in its life cycle.

Under most circumstances, the condition of a pavement over time can be represented by a curve similar to the one shown above. The worse its condition gets, the more expensive the treatment required to restore the pavement to good condition, so you want to apply an appropriate treatment in the right general area on this curve. A relatively inexpensive preventive maintenance treatment earlier in the pavement’s life cycle, while it may only bring a slight improvement in the condition of the pavement, still makes a tremendous difference if you consider that it may postpone or avoid the need for a much more expensive treatment later on.

Categories of Pavement Maintenance

There are several categories of pavement maintenance activity, and the concept is also often discussed in connection with related topics, including pavement preservation, rehabilitation, and reconstruction. To better understand pavement maintenance, it helps to have an idea of how these terms are commonly used, otherwise they may seem overlapping and confusing. The following definitions are used by the Federal Highway Administration (FHWA):

Pavement preservation: Programs and activities employing a network level, long term strategy that enhances pavement performance by using an integrated, cost-effective set of practices that extend pavement life, improve safety, and meet road user expectations.

Pavement rehabilitation: Structural enhancements that extend the service life of an existing pavement and/or improve its load-carrying capacity.

Pavement reconstruction: Replacement of the entire existing pavement structure by the placement of the equivalent or increased pavement structure.

Pavement maintenance is normally distinguished from pavement rehabilitation, because maintenance treatments do not significantly change the structural or load-carrying capacity of the pavement. Preventive maintenance is one of the biggest components of a pavement preservation program, while other types of maintenance may not be considered preservation. Here are some definitions the FHWA uses for different categories of maintenance:

Preventive maintenance: A planned strategy of cost-effective treatments to an existing roadway system and its appurtenances that preserves the system, retards future deterioration, and maintains or improves the functional condition of the system (without significantly increasing the structural capacity).

Corrective maintenance: Activities performed in response to the development of a deficiency or deficiencies that negatively impact the safe, efficient operations of the facility and future integrity of the pavement section.

Routine maintenance: Work that is planned and performed on a routine basis to maintain and preserve the condition of the system or to respond to specific conditions and events that restore the system to an adequate level of service.

Preventive maintenance is most effective when a pavement is structurally sound and exhibits little or no distress. Examples of preventive maintenance activities include surface treatments such as chip seals or slurry seals, along with thin (non-structural) overlays. When pavement distress is already present, repairs in the form of corrective maintenance may be more appropriate. This includes treatments such as pothole repair and patching, along with joint replacement or slab replacement for rigid pavements. Smaller activities like cleaning roadside ditches or crack filling may be considered routine maintenance.

Prevention and Repair

Ideally, pavement maintenance would be mostly preventive, so that the pavement surface is always in good shape and distresses are never present. A well-planned maintenance program, in conjunction with a pavement management system, can help achieve this in a cost-effective way. At the same time, it’s wise to ensure that you have the capacity to make repairs when necessary. This will help you respond to unforeseen developments and maintain the structural integrity of the system. You might say that a complete pavement maintenance philosophy isn’t just about prevention or repair, it should cover both.

Winter time in the northeast means snow and ice events over the next 3 months. As a home owner or business owner you may need to ask yourself; should I be using salt or ice melt?

Rock Salt

This has been the go-to product for melting ice during the winter months of the year. Unbeknown to many people, rock salt (also known as halite) is basically sodium chloride in mineral form. It works by penetrating the surface of ice thus forming a strong solution of water and salt, which is commonly referred to as brine. Since salt and brine’s freezing point is significantly lower than that of water, the ice will start melting, and won’t form again provided that adequate rock salt is available. Typically, rock salt establishes grit and gravel particles that increase traction on driveways, walkways, and even stairs.

Pros and Cons of Rock Salt

Rock salt remains one of the cheapest ice melting products. It is also readily available in retail outlets except when there are extreme shortages due to weather. This means homeowners should think ahead and purchase before they need it What’s more, rock salt can effectively be used to prevent the accumulation of salt in surfaces since it has a low freezing point of 25 degrees Fahrenheit.

Despite its effectiveness, several factors ought to be considered before choosing rock salt. This product may be harmful to plant life. Therefore, it shouldn’t be used near vegetated areas. Rock salt is similarly dangerous to pets since it causes gastrointestinal disorders when ingested.

Ice Melt

Ice melt products are made from magnesium chloride, calcium chloride, potassium chloride or sodium chloride. Ice melt made from calcium chloride is the most effective, and also the most widely used. Ice melt differs from rock salt because it is more pet friendly. In addition, it doesn’t harm plant life as much as rock salt. Nonetheless, some ice melt is coated with Calcium Magnesium Acetate (CMA) to make it safer.

Pros and Cons of Ice Melts

Most ice melting products that contain calcium chloride have the ability to lower the freezing point of water. Ice melt not only forms brine but also has the ability to generate chemical heat. This means it is effective at melting ice, and also does this faster than other products. Besides this, there are different varieties of ice melts, all of which serve different purposes.

Ultimately the choice is up to you. Ice melt will offer other benefits in addition to melting the snow/ice. If you have pets you may consider the additional benefits of ice melt. Of course there is always a price tag along with additional benefits.

We had a blast up at New Hampshire Motor Speedway. The car looked awesome. We had to wait out the rain but it was all worth it in the end. We spent most of the day in the garage and walking around the infield. We got to meet Matt, tour the hauler, and watch the race from the top of the pit box. Matt started 31st, and finished 15th. Check out some of the pictures from our trip.
