We all know that WATER IS THE MOST DESTRUCTIVE element to our pavements. If it rained and snowed everywhere but on our roads and bridges, 90 percent of highway and street work would be eliminated. Since that is not likely to happen any time soon, we need to prevent water intrusion into our pavements.Filling or sealing pavement cracks to prevent water from entering the base and subbase will extend the pavement life by three to five years.

Our company is Xinxiang Tongda Road New Technology CO.,ltd. Our Crack sealant "Ningway II"  is used for repair the Pavement Crack.


when applying the hot melt pavement crack sealant, you need have the follwing 3 things:


Before you can seal a crack in the pavement, you have to clean it out. This is really the more complex piece of the sealing process. First, you have to widen the crack slightly and make sure there is enough room to pour the sealant into it. This can be done with a router, which is a piece of equipment strong enough to cut the pavement on either side of the crack. Once the crack is wide enough for sealant to be poured in, it can then be prepared for the sealing process.

Second,Blow pipe.

If the dirt or debris in the crack is dry, the easiest piece of equipment to use is a simple blow pipe to clean out the crack. This is because you want the crack sealing materials to cling to either side of the crack, keeping the road intact even as it moves with the road's changes. A blow pipe will take care of these requirements.


Third,Hot air lance.

A hot air lance can be used to clean out a crack if the debris inside is more complext than just bits of dirt and pavement dust. Sometimes it's wet or sticky, and can't be blown away by a blow pipe. A hot air lance blows compressed air at temperatures around 2000 degrees, drying and clearing anything that might remain in the crack, allowing it to be filled immediately with the sealant.

 Our company can supply you high quality hot melt road crack sealant, also we can supply you the above 3 products.
