There are many benefits when proper maintenance and regular inspections are put into place when dealing with asphalt. The lifetime of your surface will increase, as well as safety and your asphalt’s worth. When it comes to asphalt driveways, roads, parking lots and trails, preventative maintenance can extend an asphalt’s useful life fifteen to twenty years, whereas doing nothing to the surface will cause your asphalt pavement to deteriorate within three to five years.
There are a few factors that may challenge your asphalt, such as location, weather and the subbase under your property. Being able to recognize problems early and having proper procedures in place will save you time and money down the road. The team at Galt Development has created a list of the types of pavement cracks you may experience, what to look for and how to repair these damages during the lifetime of your asphalt.
❖ Block Cracking may be identified by squares or circles in your asphalt pavement. This condition suggests an old or dry mix was used when the asphalt surface was laid and typically appears two to three years after installation. To repair this type of crack, try using a thin overlay or surface treatment that can seal the crack and help prevent future cracking.
❖ Edge Cracking appears along the outside edges of the pavement. These cracks are typically long and run in the direction of the road, and are caused by the soil under the road drying and shrinking, poor drainage, or excessive traffic. Edge cracking may be repaired by filling with your choice of asphalt crack seal.
❖ Fatigue Cracking is identified by numerous small cracks in a localized area and indicates a flaw in the design or installation on the asphalt surface, poor drainage, and temperature changes. We recommend full-depth patches, to strengthen and restore the surface and prevent cracking in the future.
❖ Linear and Transverse Cracking may be characterized by linear or longitude cracking occurring along the joints of the pavement. Asphalt is usually laid across large surfaces in strips or sections. If the joints between the sections are improperly constructed, cracks form. You should take proper steps to prevent water from seeping into underlying layers by filling the cracks with a combination of asphalt and sand or emulsion slurry.
❖ Reflection Cracking occurs along the surface of the pavement that mirrors the sub-layer cracking, the sub-layer joints, or shifting in the sub-layers. These cracks are usually identified as straight and sometimes grid-like across the surface of the pavement. We recommend filling these cracks with sealants and an asphalt fill product to prevent moisture from breaching the surface and causing more damage.
❖ Slippage Cracking looks like the asphalt is slipping along the surface of the pavement. These cracks are identified by wrinkles or deep open gaps, and look like crescent or half-moon shapes. These types of cracks are usually produced when braking or turning wheels cause the pavement surface to slide and deform. Slippage cracks need to be filled or partial depth patches depending on the severity of the crack.
Galt Development’s primary expertise is in asphalt installation, repair and maintenance. Our team is experienced in providing asphalt to new construction projects, as well as performing maintenance on existing commercial and residential properties. Our focus is on providing a quality product delivered with optimal efficiency. The streamlined process we employ involves our trucks bringing the asphalt to the site, placing the asphalt into the paver, laying down the mat and quickly rolling it. This process allows the pavement to reach full compaction with a smooth finish before the product hardens.
