How to Evaluate the Effectiveness of Asphalt Crack Sealing
The process of asphalt crack sealing is a great way to improve the appearance of your driveway or parking lot. There are several factors to consider before choosing the right type of sealant: cost, environmental impact, and quality. Listed below are some of the main factors to consider. Once you've decided which method to use, you can move forward to the next step: evaluating the quality of sealants and the effectiveness of your crack sealing project.
Cost-effectiveness
To determine the effectiveness of different methods of crack sealing, researchers have analyzed the performance of unsealed and sealed pavement. Most studies have focused on unsealed pavement and found that sealing improves pavement performance. However, not many studies have compared the cost-benefit of different techniques. This research aims to address this gap. In this article, we will discuss the differences and similarities between these two methods.
Although it is an important preventive maintenance strategy, pavement experts differ on which method is more cost-effective. Using literature review, a survey, and field performance data, researchers have developed a cost-effectiveness guideline for pavement crack sealing. The results from this study provide a basis for comparing the various methods. Crack sealing is also more expensive than crack filling. Despite its initial high cost, crack sealing may offer longer service. More research is needed to determine whether higher performance materials are truly beneficial.
Environmental impact
While asphalt crack sealing may not have a negative environmental impact, it can have a detrimental impact on pavements. When applied improperly, crack sealing can cause damage to asphalt pavements due to moisture entrapment. Unlike other types of surface treatments, crack sealing prevents water from escaping upwards. In fact, crack sealing can reduce the lifespan of pavements by 1.1 to 2 years. This can lead to an increase in maintenance and rehabilitation costs.
This study shows that a crack seal technique can reduce emissions of nitrogen oxide and sulphur dioxide by 50 percent. However, the crack seal method has the lowest overall emission reduction. The researchers suggest that all methods of preventive maintenance reduce carbon dioxide emissions. They recommend that new pavement studies incorporate sustainable pavement management components and consider the environmental impact of asphalt crack sealing. The study concludes that future pavements must incorporate a comprehensive life-cycle assessment to evaluate their overall environmental impact.
Quality of sealant
When determining the quality of asphalt crack sealant, consider the following factors: Size, shape, moisture content, and repair method. Crack sealant's success depends on several factors. Generally, a crack less than 20% in crack density requires a more flexible product. In contrast, a larger crack density requires a stiffer sealant. In addition, sealant's tackiness decreases after it has been cured.
When choosing an asphalt crack filler, make sure to choose one with the right adhesive properties. Asphalt filler is not rubberized, and it might dislodge if the pavement moves. Sealant, on the other hand, expands and contracts with the pavement. If the crack filler doesn't expand and contract with the pavement, it is not the right choice. For this reason, choosing a high-quality asphalt crack filler is imperative.
