Road maintenance offers several direct and indirect benefits. Some of them are smoother driving, less gas consumption and longer road availability. Usually, two main aspects of maintenance are considered: corrective maintenance, including repair work such as filling holes, filling cracks and cleaning. The other one is preventative road maintenance, it includes closing cracks and repairing surfaces to ensure slow road damage.

Digging holes is the most profitable activity for corrective maintenance. This is also known as post-treatment, which involves spraying a layer of asphalt on an existing road. Stone chips are then spread on this layer and then rolled with a road roller.
Another method is called Asphalt Resurfacing, which uses hot mix asphalt to correct surface imperfections and restore surface uniformity. As well as patching the hole patches, one needs to focus on minor changes and small stabilization before these problems turn into much bigger headaches.
Crack sealing is another activity in road maintenance. Sealants and bitumen are used to fill in road joints and cracks to prevent water from entering the surface, making roads longer. Another form of preventive maintenance is a surface correction. During this maintenance activity, a thin film is created to improve the integrity and sealing of the surface.
Everyone wants their environment to be clean and tidy. To solve this problem, the focus should be on cleaning/clearing roads to remove street trash, reduce pollutants and lower government maintenance costs, usually to keep the drainage system clean.
