Pavement Solutions have a long history of working within the paving industry. Climate change is one of the most significant challenges road asphalt pavements face. It is essential to understand the impacts of climate change on pavements, their materials, and design.
Permeable pavers allow rainwater to absorb into the ground rather than flow into a drainage system. This reduces the amount of stormwater that is diverted to sewer systems, which can put a strain on local wastewater treatment plants. Additionally, it helps to reduce the concentration of pollutants in stormwater runoff.
Non-permeable pavement, such as concrete and asphalt, requires a complicated drainage system to manage the flow of water through the surface. These types of systems can lead to the buildup of harmful materials, such as motor oil and fertilizer, in drains and sewers. Permeable pavers help to prevent these types of pollutants from contaminating the surrounding environment by allowing the water to soak into the ground and re-establishing a natural hydrologic balance.
By reducing the volume of stormwater that is discharged into sewer systems, permeable pavers help to reduce the risk of flooding and damage to buildings and structures. They also reduce the need for costly and time-consuming maintenance to sewer systems. This type of pavement is ideal for large parking lots, where water can easily pool and cause safety hazards.
When compared to traditional paving methods, PICP is significantly less expensive to construct and install. This is primarily due to the fact that it doesn’t require as much in the way of specialized equipment. In addition, it can be constructed in a fraction of the time that it takes to lay concrete or asphalt.
One of the biggest advantages that PICP offers is its ability to be used in locations with high traffic volumes and weights, such as fire halls and shopping centers. Unlike standard pavement, PICP is strong enough to support the loads of trucks and other vehicles that use these areas on a regular basis.
Another benefit of permeable pavers is that they can be designed to reduce the effects of the urban heat island effect. By choosing lighter-colored pavers, it is possible to create a paved surface that will reflect rather than absorb heat. This can help to keep a city or town cool and help to lower energy bills for residents.
A surprisingly cost-effective way to protect your asphalt investment is by seal coating. The process involves applying a coat of coal-tar, asphalt emulsions or acrylics to the surface of your asphalt pavement to seal out water, oils, chemicals and UV damage, prolonging its life. The dark color also helps to reflect the sun’s rays, keeping the asphalt warmer, which can prevent cracking.
Prior to seal coating, workers will thoroughly sweep the area and remove any debris or repairs needed. Then, the pavement will be primed to help the new coating bond with the asphalt surface. Workers must wear protective clothing and masks during this phase, as some of these toxins are carcinogenic and can be harmful if ingested or inhaled. Depending on the size of the job, workers can apply the seal coat by spraying it or using a squeegee machine to smooth out the surface.
Sealing the surface of your asphalt parking lot makes it look like new again and adds a layer of protection from weather elements, oil spills and traffic abrasion. It also allows the asphalt to remain flexible, which can reduce cracking and extend its lifespan.
As an added bonus, sealcoating can improve the drainage of your parking lot by filling in the small cracks that let water seep into the blacktop and weaken it. In addition, it provides a barrier to snow removal equipment that may cause damage when driven over the surface.
When your parking lot looks old and damaged, it can turn off potential customers or make a bad impression on visitors. A fresh coat of sealer can transform the appearance of your business and improve its curb appeal, boosting your sales and your property value.
It’s best to perform this maintenance during dry weather, as the sealer needs to dry and cure completely before it’s exposed to rain. If you aren’t sure whether your parking lot is due for a sealcoat, watch out for signs that it’s time to reseal: gray spots on the surface, fine cracks and weeds sprouting up around the edges of your asphalt.
Aside from a complete asphalt overlay, crack filling is the most cost-effective way to repair existing pavement. As its name suggests, it involves filling isolated cracks with liquid sealants. It is especially useful for preventing future deterioration of your parking lot caused by water penetration, as it prevents moisture from seeping into and damaging the base materials. This process works for both non-working and working cracks, and can be used on both hot and cold asphalt surfaces.
To properly prepare your cracks for the crack filling process, you must first ensure they are free of debris and dirt. It is also important that the cracks are dry in order for the filler to adhere correctly. Cracks must also be measured to determine the appropriate crack fill supplies to use. Cracks that are less than 2 inches wide can be filled with a rubberized crack filler; however, cracks that are wider will require hot pour crack sealing machines.
Working cracks are horizontal or vertical movements that occur in asphalt pavement due to temperature changes, traffic, or poor drainage. If left untreated, these cracks will allow water to flow through the pavement and erode the base materials; this can cause potholes or even total pavement failure. Crack sealing is the best way to protect your pavement from the intrusion of water, and it can extend the life of your asphalt significantly.
While crack filling is an effective treatment for working cracks, it is not a permanent solution. It is a cost-effective choice for those who want to prolong the life of their pavement, but it can only last one or two seasons depending on climate conditions. For this reason, crack sealing is recommended for those who want a long-term solution to their pavement issues.
A more permanent solution is a drainage system, which can be installed under your pavement to promote efficient subsurface flow. This type of drainage system is built with a perforated pipe connected to a stormwater drain or catch basin. The perforations and round river gravel in the drainage tile function to filter incoming rainwater, which is then dispersed into the pipe or drain. This drainage solution is ideal for parking lots with a high amount of rainfall and is especially helpful in reducing erosion under the pavement.
Parking Lot Maintenance
Whether you manage a public, commercial or industrial property, it is vital to have a parking lot maintenance plan in place. Not only does it keep your facility safe and functional, but it also enables you to extend the lifespan of your asphalt and save money by avoiding costly repairs.
Regular repair and maintenance can help you get the most out of your parking lot’s lifespan, preventing cracks from growing into potholes. It can also mitigate the effects of water permeation and prevent damage from accumulating below the surface.
Asphalt repairs can be done as soon as damage occurs, reducing the risk of more extensive and expensive repair costs. Performing preventative services, such as crack filling and seal coating, helps to maintain the integrity of the base and protects the surface from erosion and deterioration.
Improving the drainage of a parking lot is another important element in its maintenance. Standing water breaks down the bonds between the asphalt binder, sand and rock aggregate that make up the pavement. This moisture can weaken the structure of the driveway or walkway and create problems like cracking, crumbling, and rutting.
In order to prevent these issues, the parking lot should be graded to ensure that water flows off the surface and towards the perimeter drains or culvert. Catch basins should be regularly inspected and cleaned to ensure that they are not blocked. Adding internal curbs to direct the flow of water will also help to reduce the amount of standing water.
Performing regular maintenance tasks like sweeping, resealing and snow removal can also help to protect the longevity of your parking lot. Sweeping removes dirt and debris that can contribute to cracking, while resealing protects the surface from water penetration and UV radiation. Snow removal reduces safety hazards and keeps the pavement clean for pedestrians and drivers alike.
Although it may be tempting to ignore a parking lot that is showing signs of wear and tear, doing so can result in costly repairs and lost revenue. The best way to tell when it’s time to replace a lot is to contact a professional to discuss the condition of the surface. A professional can advise you on what services are required to restore the surface and how much it will cost. They will also be able to suggest alternatives that will improve the efficiency and longevity of the lot, without the need for full replacement.
