A bitumen surface, when sealed, gives your parking lot or driveway a more durable and lasting finish – one that you can use for a longer duration. Sealing is important, as it allows you to preserve a pavement and keep it looking good.
Surface Treatments for Bitumen Driveways
When bitumen driveways in Sydney are sealed, they are given bituminous surface treatments or BSTs. This type of treatment is not exclusive, as it can reference a whole range of methods to create a better surface. Usually, the term, however, refers to sealcoating a driveway. This technique involves spraying a layer of asphalt before adding a tier of aggregate on the top. BSTs may be applied to the base or a current pavement. When this method is used, it is meant to save on the costs of paving.
Before you contact a company about paving or sealing your driveway, you need to realise that all pavements degrade over time. The life cycle depends on how the pavement is constructed and the ever-changing environmental conditions. Because Australia regularly receives extremes in weather and temperatures, you need to ensure the reliability of your driveway or parking lot.
Avoid a Chain Reaction
During pavement deterioration, only a few distresses may affect the pavement, permitting it to stay in fairly good condition. However, with the passage of time and as more distresses form, a chain reaction begins to occur. For example, once a crack develops (because of expansion and contraction), it is easier for water to access the bitumen layer and absorb into and weaken the substrate.
Why Seal Coating Is Important
The only thing you can do to extend the life of a bitumen pavement is to seal coat it for added protection. This additional measure will ensure that your pavement will last longer and perform better for you. By practicing the necessary maintenance, you can slow the rate of deterioration by the correction of small defects. This is imperative, as these types of flaws can worsen to create more defects.
Why Pavements Become Hard to Manage
If you do not stay on top of maintaining a pavement, the defects eventually become too large for management and correction. At this juncture, you can only use rehabilitation to take care of cracks and crevices. That is why, when taking a life cycle cost analysis (LCCA) of a bitumen pavement, you will find that it literally pays, in the long run, to have it sealed.
Surveying the Costs
An LCCA is done over a set period – usually 10 or 20 years. The costs usually cover the installation cost, maintenance expense, rehab costs, and salvage value at the end of the period. By accounting for these expenses, you can see the wisdom of maintaining a bitumen drive and installing this type of pavement upgrade.
