As asphalt surfaces age,erode and become brittle, proper periodic assessment and treatments are essential in maintaininga quality surface and infrastructure. The appropriate course of action can save time and money bymaking sure the maintenance applications are matched to the severity of the pavement problems.Understanding DefectsThere are typically three types of asphalt failures: Surface, Bond, and Structural Failures. Forsurface failures there can be raveling, and transverse or longitudinal cracking problems. Ravelingis the loss of aggregate from the surface as a result of abrading action from wheels. Longitudinalcracks run in the direction of traffic and transverse cracks are 90 degrees to longitudinal cracks.Longitudinal cracks are typically caused from shrinkage.Bonding failures are usually in the form of slippage between two layers of surfacing causing cracksin the upper layer. In some cases the combination of bonding and crack failures causes the toplayer to flake off in chunks.The most severe defects are structural cracking which can include fatigue cracking and rutting.Fatigue cracking results from the surface being flexed up and down from heavy loads going by.The cracks are very close together and look like an alligators skin. This defect occurs when theunderlying road section can no longer support the loads being applied to the pavement. Oneheavy truck can flex and damage a road more than thousands of cars passing over the same spot.Rutting is a depression of the pavement in the wheel path and is usually continuous throughout apavement. It can occur in just the asphalt layer or throughout the entire infrastructure of asphalt,base, and soil.Types of TreatmentsThe difference types of actions one can choose will vary with the defects and extent of damagefound on the pavement surface. The potential solutions can include surface seal coats, crackfilling, slurry seals, selective dig-outs and patching, or full overlays.Within the use of surface seal coats, there are several to choose from. They include slurry, cape,micro-surfacing, fog, and rubberized chip seals to name a few. A fog seal contains no aggregateor sand and is spray applied to keep the surface aggregate in place. A surface seal coat is amixture of sand and asphalt emulsion with other fillers. It provides a uniform black surface andprotects from UV damage and reduces water intrusion. A slurry seal consists of emulsified asphaltbinder, a graded fine aggregate additive and water and is applied by machines with pressure.

An overlay is used over the top of an existing pavement surface to strengthen and protect theoriginal structure. It can be applied at various thicknesses and also can be rubberized. Sometimesmilling is required before the overlay when excessive heights are an issue to prevent any potentialtrip hazards. Also the use of paving grids and fabrics over the top of an existing cracked pavementcan provide additional strength and water intrusion protection.Choosing a Plan of ActionParking lots primarily utilize asphalt seal coats, slurry seals and sand seals. These seals aredesigned for use in areas that will have constant turning forces. The oils are harder than chip andcape seal oils and lessen tire marking on the pavement.Streets generally utilize slurry, chip, cape seals or micro-surfacing. These treatments varydepending on the conditions of the road. Crack filling and dig-out repairs must be completed priorto the placement of the surface treatments to obtain the maximum performance life.So you can see there are various failures modes from minor surface issues to major structuralfailures and there are a wide variety of treatments to deal with them. Plus following an overallmaintenance plan through the lifecycle of the pavement will help prevent early failure and maintainthe asset through its expected lifetime. The best way to get started is to have an asphaltengineering firm or quality asphalt contractor assess your situation and provide guidance on whatthe most economical course of action would be for your situation.Miles Labbitt recommends you always have a pavement maintenance plan professionally done toprotect your valuable assets.
