Question:Why cracks appear in your pavement?

Answer:As we all know, all pavements constructed have their own life limits because of some typical natural inevitable reasons like weather conditions or artificial traffic usages. Sometimes the cracks are causes by the second rate pavement constructors with not that superior equipment. Of course, other factors such as erosion of the underlying surface and even earthquakes can cause pavement cracks.

Question:Why do we need to maintain our pavement once it appears cracks?

Answer:Generally, reasons for cracks getting larger can be quite distinguish in different areas. For example, in cold climates, typically, water seeps into a small crack in the pavement. As water freezes, it expands, making the crack bigger. When this ice melts, a greater amount of water can get into the enlarged crack. This process repeats, each time making the crack larger and then when cars drive on it, it will eventually cause the top layer of asphalt to break off. While in warmer climates, the constant wear of vehicles and heat from the sun dries the asphalt and causes the top layers of asphalt to crack, which can widen from rain water. Little cracks like in driveways are usually caused by roots which can cause cement to crack and break up. As the days go by, this entire litter crack will be more serious if you do not pay enough attention to this situation and the coincidences will be way of our expectation. That’s the reason why it is so necessary for maintaining your pavements and keeps it sound.

Question:Why hot sealant is better than cold sealant?

Answer:There are two kinds of cracks sealant acquainted to the public. One is hot pour material, the most commonly used, providing a good performance in most cases and another one is cold pour emulsion crack sealants. What are the differences between this two repairing approaches? Which one is your option? In an overall evaluation of the survey, it was reported that hot pour sealants performed better than cold pour sealant. Hot-pour crack sealer is melted and applied, then cools to a pliable, rubber-like consistency, allowing it to expand and contract with the crack while cold-pour crack sealers can be a water or asphalt based product that is applied to cracks in a liquid form, and then dries to a solid. However, cold-pour crack sealers usually do not perform as well, due to their lack of flexibility when dried. Therefore, it goes without controversy that hot sealant can well connect to the road base and extend the pavement’s life-cycle for its superior material performance and water resistance compares to the cold sealant.

Question:What is Dseal sealant and Why Dseal?

Answer:You may quest, what’s the best option for maintaining or repairing my pavement based on the considerations on human safety, the most effective, money-saving and easy-applying if hot sealant is on my side. The answer will go to Dseal sealant definitely. Dseal hot sealant, a very important and professional product for sealing and filling cracks during the pavement maintenance processes. Developed from a really technical engineering group and tested by several professional pavement maintenance organizations, it turns out Dseal is the best option for its cost-effectiveness performance and life cycle costs of hot rubber asphalt crack sealant. Here are the reasons listed bellows for choosing Dseal: Dseal sealant is durable and long lasting ensuring overall cost savings. Dseal sealant is really simple for filling applications Dseal sealant offers the possibility to repair damaged areas quickly as it was developed for repairing pavement cracks. Dseal sealant has different versions; it will meet your requirements no matter for Arctic areas or tropical areas. Dseal sealant can be subjected to traffic or other stresses within 20 minutes depending on the thickness of the repaired area. Dseal sealant can be heated in a slapping speed about 15 minutes with our professional heater.

Question:Why do I need Dseal Heater?

Answer:Normally, most people may consider use asphalt cooker, grill or microwave to do this heating task. But I do feel eligible to point it out that the above heating process would threat our personal safety to some extent even though they keep emphasizing how safe those heating approaches are. That’s the reason why we dedicated in developing our professional Dseal Heater in order to keep our customers safe during the heating application. After a great amount of experiment, it is no doubt about that Dseal Heater is the faster heating device for viscous material heating. It only takes about 15 minutes to finish the whole heating process. What’s more, the whole heating process is really easy to operate and it only needs one person to perform the heating task. With this professional Heater, you can do something else when heating because once the heater power was connecting; the whole heating process will go automatically. And it will shut off when the asphalt reaches to the room temperature and re-heating while the temperature is getting low.

Question:About Dseal and Orderbid.


Dseal, a product brand published by Orderbid international group, related to asphalt relevant products including pavement maintenance materials (Hot sealant) and paving materials (SBS road base asphalt). All kinds of our products have 3 versions which are tropical version for extremely high temperature areas use, normal version for variable zone use and arctic version for low temperature use. Therefore, Dseal can meet all your needs for repairing pavements whether to arctic areas or tropical areas.

Question: Why I can’t regular asphalt instead of professional asphalt?

Answer:Are you thinking about using the normally asphalt material to repair your pavements instead of using the professional crack filler? Please don’t! The professional crack filler is a product released after being tested by several relevant elements such as Cone Penetration, Softening Point, Flow, Resilience and Bond. A great many of technical engineer manage hundreds of thousands experiment to research, develop, experience and put it into practice to prove its stickiness and other performances before these products come out. There is no comparison between regular asphalt and professional crack filler. Your pavement will only go worse if you choose a regular asphalt filling process.

Question:What kind of situations do I need to add sand/stone to the cracks?

Answer:For all your attentions, when the cracks/joints are larger than 5MM, there will be a need for adding coarse sand and gravel to cracks before pouring asphalt in to make sure the immobility and adhesive ability to the pavement.

Question:Why hot sealant needs to be conducted in dry environment?

Answer:Even though we all know how efficient Dseal hot sealant is for maintaining your pavement, you sill need to bear in mind that hot pouring material was supposed to apply in dry climate, which would guarantee the cohesiveness and immobility to the pavement rampart and improve the performance of sealant. In a word, applying hot sealant in dry climate can not only improve the property of product itself, but last more life- cycles to your pavement. While in humid climate, all these performances will be affected lower stickiness, lower cohesiveness and less life-cycle. Attention: do not apply in HUMID climate.
