Asphalt Pavement starts to deteriorate soon after it is laid down. Lubricants and fuel dissolve it, while water softens it with sunlight accelerating its oxidation, thereby breaking down the binder. You could call in the asphalt contractors Brisbane has available if such a thing happens. The unsealed blacktop could within a period of just fifteen to twenty years lose half its thickness as highlighted below:
- The original black color starts going pale within a year, even as the binder asphalt starts losing plasticity
- Hairline cracks form
- The entire thickness gets oxidized and brittle after five years only, developing a light gray color
- Cracks extend clear through pavement by the eighth year
- Material loosens on top
- Base fails as water soaks through
- Areas with phenomenal cracks then become potholes in a year
- The entire surface breaks up in fifteen years
You may check for a few signs that would let you know if your parking lot requires immediate professional attention, perhaps by asphalt contractors in Brisbane as follows:
- Rough Asphalt
The asphalt surface of your driveway may appear somewhat rough, with the tops of aggregate or rock showing through. Pieces of rock might as well be emanating from within it. All these are indicators of a parking lot that requires sealing and repair. Areas that exhibit excessive roughness will normally require the installation of new asphalt skin patch before seal-coating takes place. The Asphalt Contractors Brisbane has to offer may perform this action for you, which extends the lifespan of the seal-coat upon its application onto the affected areas.
- Cracked Asphalt
Cracks that appear in asphalt could be due to excess water lying underneath the parking lot or long-term failure to undertake proper seal-coat maintenance. Such areas could be repaired either by rubber crack filling or their removal and subsequent replacement with new asphalt. It all depends upon the severity of the damage, with tree root pressure occasioning cracks eventually.
- Worn Stripes
The striping and stenciling of your parking space may appear worn in some way, with old lines being visible through the old seal-coat. All these show the timing is right to consult with Brisbane Asphalt Contractors for instance for seal coating and re-striping of the parking area. For any parking lot, striping is the part most noticeable and it helps a lot to have it done neatly.
When selecting an asphalt contractor for the project, ensure first asking for references of any previous jobs completed by the professional. It is important following up with such clients to assess their level of satisfaction with the work undertaken. Contractors can differ markedly in their level of performance and excellence in this kind of work.
Ascertain as a rule of thumb that your prospective asphalt contractors Brisbane has, for example, utilizes a 10 percent maximum amount of water for diluting the seal-coat. You should end up getting a thicker coat of sealer this way, which would then last a very long time.
