You can maintain the pavement by applying seal coat. Seal coat is just a material that can be poured directly onto the surface of asphalt or concrete slab. By doing this it will make the pavement to be water resistant once it has come in contact with the surface. Try at all means to protect the pavement from water since it is not healthy for pavement life.
In maintaining the pavement you should avoid using rock salt. It is advisable that you avoid using chemicals or substances that contain rock salt on the pavement especially during cold months. You find that these substances can melt through ice very quickly as a result damaging the asphalt layer through its corrosiveness. There are some substances that when used will make the ice to melt and increase traction such as sand and kitty litter.
Another maintenance tip that you should apply is to clear the pavement. One thing that you should do is to clear the pavement to remove dirt and debris. If you want to know some of the things that do create problems to pavement is dirt and debris as they always block the drainage system making the water to stand still on the surface of the slab. With time this will cause the surface to break down over time allowing water into the sub base. Which will in turn make it to be soft exposing it to potholes and big cracks. Therefore, it is important that you sweep the pavement regularly so that the dirt does not block the drainage.
In addition, you should also fill the cracks to maintain the pavement. You should make sure that you fill the cracks immediately you notice them. You should not assume this as it is going to prevent the vegetation and water from interfering with the pavement and this will ensure that it is always dry, solid and strong. You should also note that not all cracks require sealing but there are wider openings that should be filled even the smaller ones you can seal before they develop into bigger cracks.
Another thing that you should do is to maintain the drainage. When it comes to drainage one of the things that you should start with is to make sure that there is no water that is standing on the pavement. This is because when there is proper drainage it will improve the life of your pavement by very many years. Therefore, you should check the drainage regularly to ensure that there is no blockage as this will help you in maintaining the internal structure of the drainage system.
