More About Highlands Pavement Maintenance

Do you have a plan in place for your facility’s asphalt maintenance? Proper periodic assessment and treatments are important in maintaining a quality surface and infrastructure as asphalt surfaces mature, erode, and become brittle. By ensuring that the maintenance applications are matched to the seriousness of the pavement issues, the required course of action will save time and money.Do you want to learn more?

Defects: An Overview
Surface, Bond, and Structural Failures are the three most common forms of asphalt failures. Raveling and transverse or longitudinal cracking may occur as a result of surface failures. Raveling is the removal of aggregate from the surface as a result of wheel abrading. Transverse cracks are 90 degrees to longitudinal cracks and run in the same direction as traffic. Shrinkage is the most common cause of longitudinal cracks.
The most common cause of bonding failures is slippage between two layers of surfacing, which results in cracks in the upper layer. The top layer will flake off in chunks in some cases due to a combination of bonding and crack failures.
Structural cracking, which includes fatigue cracking and rutting, is the most serious defect. Fatigue cracking occurs as the surface is flexed up and down by passing heavy loads. The cracks are very close together and resemble the skin of an alligator. When the underlying road segment can no longer withstand the loads being added to the pavement, this defect arises. A single large truck can flex and damage a road more than tens of thousands of cars going by. Rutting is a depression along the pavement in the wheel direction that generally runs the length of the pavement. It may occur in just the asphalt layer or in the entire asphalt, foundation, and soil infrastructure.
Treatments that are available
The various types of actions available can vary depending on the defects and level of damage discovered on the pavement surface. Surface seal coats, crack filling, slurry seals, partial dig-outs and patching, and absolute overlays are all possible solutions.
There are many types of surface seal coats to choose from. Slurry, cape, micro-surfacing, fog, and rubberized chip seals are only a few examples. A fog seal is a spray-applied material that contains no aggregate or sand and is used to hold the surface aggregate in place. A surface seal coat is made up of a combination of sand and asphalt emulsion, as well as other fillers. It creates a consistent black surface, protects against UV rays, and decreases water intrusion. Slurry seals are made up of an emulsified asphalt binder, a graded fine aggregate additive, and water, and they’re applied with pressure by machines.
To reinforce and secure the original foundation, an asphalt is applied over the top of the current pavement surface. It comes in a variety of thicknesses and can also be rubberized. Where excessive heights are a problem, milling can be needed before the overlay to avoid any possible trip hazards. Overlaying paving grids and fabrics on top of an existing broken pavement can also add strength and protect against water intrusion.
