Paving repairs are essential for keeping a street’s condition. A timely repair can improve its longevity, and regular maintenance will keep it in great shape for years to come.
Paving surfaces come in many varieties, from concrete to pavers adelaide and asphalt. Each requires its own specific treatment to maintain its optimal appearance.
Crack Sealing
Crack sealing is an economical paving repair method that can significantly slow the rate at which pavement cracks form. It’s an efficient way to extend the life of your asphalt pavement.
It is especially essential if you live in an area with frequent climate changes, such as hot and humid summers and harsh, cold winters. These extremes can cause pavement expansion and contraction which in turn causes cracks to widen rapidly.
Therefore, applying crack sealant early in the life of your pavement is recommended. Furthermore, visually inspecting previously sealed cracks annually is a wise idea to guarantee its protection and help avoid costly expenses for pothole repairs.
Crack sealing is the process of applying an adhesive material to cracks on the surface of asphalt pavement, blocking moisture and incompressible materials from entering into the structure. There are various materials that can be utilized for crack sealing, such as hot-applied sealant, asphalt rubber and self-leveling silicone.
These materials must have excellent adhesion or bonding to pavement and be compatible with existing asphalt pavement. Furthermore, they should be resistant to cracking, aging and weathering.
Some materials require surface preparation, such as eliminating loose aggregate or dust. This step ensures the cracks are clean and solid so the crack seal can adhere to the asphalt surface.
Another step is to route the cracks. This requires using a mechanical routing machine to widen the gaps, creating an even surface for hot-rubberized crack sealant to adhere to.
This is an essential step, as it allows the crack sealant to penetrate into the base of the pavement and create a strong, long-lasting barrier against water and other incompressible materials. Once routed, they should be sanded to remove any debris and prepare the surface for applying new crack sealant.
Crack sealant comes in several different placement configurations, such as flush fill, overband, reservoir and combination. Each has its advantages and drawbacks so it’s essential to discuss the process with your client and carefully weigh all options before making a final decision on the best treatment for them.
Pothole Repair
Potholes on asphalt surfaces are both an inconvenience and potential hazard for drivers. They can damage wheels, exhaust systems and front-end components; additionally, potholes weaken pavement, making it more vulnerable to deterioration and cracking.
Pothole repair is an integral part of pavement maintenance. Not only does it save motorists money on repair expenses, but it also improves road safety and reduces traffic delays. Furthermore, pothole repairs increase the lifespan of roads, saving contractors and highway managers money on upkeep budgets.
Depending on the size of a pothole, various methods of patching can be employed. These range from straightforward “throw and go” repairs to high-tech proprietary patch mixes.
Potholes form when water seeps into open cracks or voids in the pavement. This moisture then soaks into the soil beneath and erodes away at the base of asphalt, leaving a hole. Traffic then pushes against these weak areas, further weakening it until cracking and crumbling begin to appear.
This process often leaves behind additional voids that permit air to escape and become trapped beneath the surface of the pavement. These air voids enlarge as pavement deteriorates, eventually leading to large potholes.
Preventing potholes from becoming larger requires preemptive action. Utilizing a pothole repair material before they get out of hand can save both time and money on future repairs in the future.
Pothole repair materials should consist of aggregate and a binder. Cold mix asphalt is one popular option, but hot mix can also be successful.
When selecting a pothole repair material, HAPAS (Highways Authority Product Approval Scheme) approval should be taken into account. These products have undergone rigorous testing to guarantee their long-term durability.
One of the most commonly used pothole repairs is “throw and go,” in which asphalt patch materials are thrown into the hole and compacted by a truck or heavy equipment operator. While this approach may be inexpensive and quick, its high failure rate makes it unreliable.
Edge Crack Repair
If your asphalt pavement has edge cracks, it is essential to address them before they worsen. Edge cracks are typically due to inadequate support at the outer edges of the pavement and may indicate deeper-rooted issues like poor drainage or inferior base/sub-base quality.
If you want to prevent edge cracks on your pavement, applying sealcoating after curing will protect it from weathering, temperature changes and overall usage damage.
You can fill in minor edge cracks with crack sealant to protect against further damage. However, it’s essential that these repairs only be done by trained professionals.
Additionally, it’s essential to use the appropriate paving material for the job. Always opt for a high-quality product designed to shield your asphalt from external elements.
Asphalt cracks come in many forms, such as fatigue, longitudinal, transverse, block, reflective and slippage cracks.
Longitudininal cracks refer to those located parallel to your asphalt’s centerline, often due to thermal stress, traffic loadings or joint construction issues. They could also be due to shrinkage of the pavement or reflection of existing cracks on underlying layers.
Cracks on paved surfaces can be caused by a number of factors, such as weak asphalt mixes, weak pavers and inadequate bond between them and their base. If you observe cracks in your surfaces, contact an experienced paving contractor right away for assistance.
Aside from allowing moisture to seep into your asphalt base, cracks can also let loose dirt and debris that could further wreak havoc. That is why it is essential to thoroughly clean paved areas before applying new sealant.
Reflective cracks, also known as grid-like patterns on your asphalt surface, can be caused by a poor base, inadequate drainage or frost damage to the underlying layers.
Paver Restoration
Pavers make for an excellent surface material for patios, driveways, walkways and planters as they’re cost-effective, attractive and simple to maintain. Unfortunately, like all materials they can deteriorate over time so some upkeep is required in order to keep them looking their best.
One of the most essential steps in maintaining your pavers is sealing them. Not only will this protect them from stains and dirt, but it also makes your pavers look their best and increases the resale value of your home!
At Abbadessa Bros, we carry all the paving sealers you need to keep your pavers in excellent condition for years to come. Our sealants are specifically formulated to bring out the natural color of your brick and come in various sheens such as Matte, Semi-Gloss, and Higher Gloss options.
Once we’ve sealed your pavers, it is essential to keep them clean and free of weeds. Over time, weeds can shift your pavers and prevent proper interlocking between joints. Regular brushing of your pavers as well as applying granular weed preventative between joints is an effective way to maintain their condition.
Maintaining your pavers to keep them free of dirt and weeds will guarantee they last for years to come! A coarse-bristle broom and paver cleaner are ideal tools for this task.
