Asphalt Maintenance

Sealcoating extends the life of the asphalt, improves curb appeal of your property, and saves you money in the long run.

 

Asphalt deteriorates due to oxidization, climate, traffic load, moisture penetration, and exposure to solvents. ​Routine maintenance will prevent premature replacement and enhance the curb appeal of your whole property. 

Our seal coat mixture is commercial-grade, environmentally-friendly, water-based and mineral-filled asphalt emulsion pavement sealer. It is fortified with special surfectants to promote superior adhesion and durability. 

 

Select aggregate is job-mixed to produce a slip-resistant coating that dries to a deep, rich black colour. It is applied either by pressurized spray equipment or by hand with a squeegee. 

 

Sealcoating:

  • Protects asphalt from oxidation, oil and chemical spills.

  • Enhances the appearance of your building and landscape.

  • Prevents premature alligator cracking and formation of potholes by providing protection against water penetration, rain, frost and snow damage.

  • Reduces long term repair costs.

Crack filling with Heated Liquid Asphalt is a preventive maintenance to prevent entry of water or other non-compressible substances such as sand, dirt, rocks or weeds into the pavement. 

 

Crack sealant is typically used on early stage longitudinal cracks, transverse cracks, reflection cracks and block cracks. Fatigue cracks are most often too extensive to warrant filling with crack sealer; they usually require an area treatment such as a patch or reconstruction. 

 

Crack filler material is typically a rubberized asphalt or tar material. Cracks and joints 1/4″ or greater should be cleaned of any incompressible material including old sealant, and then sealed. ​​ Before applying crack sealant, cracks need to be routed out and cleaned. Crack sealing is best done in moderate temperatures and is most effective if performed immediately after cracks develop. The  average performance life ranges from about 3 – 8 years. Combination of cracksealing and sealcoating is a cost effect measure which will extend pavement life.

Patches are a common method of treating an area of localized distress, especially potholes.

Types of Patches are:

  1. Full-depth replacement: where the entire depth of pavement is distressed, the existing surface is saw-cut and removed, and the subbase is repaired and reinforced. Then, a new asphalt surface is laid and compacted;

  2. Partial-depth replacement: where there is more than one layer of asphalt, only the deteriorated layer is replaced;

  3. Resurfacing: For minor depressions or cracking, new asphalt layer is laid and compacted over existing asphalt surface after tack coating.

Patching material can be Hot Mix Asphalt or Cold Mix Asphalt material as well as certain types of slurries. Although it may seem that the hot mix asphalt technique would produce a higher quality patch than the cold mix asphalt, the “throw-and-roll” cold patching technique proved just as effective. (Federal Highway Administration Long Term Pavement Performance (LTPP Comparison) Study, 1998).
