Asphalt and Bitumen pavements that are properly designed and constructed should not need maintenance for a number of years. Potential maintenance consists of the following types of activities.
Asphalt and bitumen pavements crack due to various reasons but the most common is either age or movement of the sub-base. This is usually the start of a pothole or larger failure.
The most cost-effective maintenance of a driveway or car park is to place a thin asphalt layer to the surface before it breaks down severely. Usually this is “keyed in” to the existing levels so you don’t have any raised areas, usually where there are drainage pits/manholes, ramps where people are walking and start and finish of the job where vehicles will be crossing over from existing to new pavements.
