Services

Below you can find more information about each of our asphalt maintenance services and how they can each help you in prolonging the life of your asphalt.

 

Crack Seal

Crack seal is your first line of defense to preserve asphalt from failing.

Crack Sealing offers important benefits such as preventing water from leaking into and weakening the sub-base, extending pavement life by preventing crack growth, and protecting pavement adjacent to the cracks. Crack seal uses a hot applied sealant to fill cracks and joints to prevent invasion of surface water between the layers of asphalt and base rock below which helps protect against potholes and deterioration.

For the sealant to adhere properly, cracks must be cleared of debris and weeds as well as be clean and dry. Cracks may be routed prior to the sealing process which provides more surface area for the sealant to adhere to, giving better results.

Slurry Seal

Slurry Seal is one of the most cost effective and efficient methods used to prolong the life of existing asphalt. This process extends the life of pavement by protecting the existing surface from the effects of aging and weather. Slurry Seal protects existing pavement by coating it with an emulsified mixture of asphalt & aggregate. Fillers are also added and can consist of portland cement and aluminum sulfate. They are added in small quantities for stability.

There are three primary grades of slurry seal used in California based on the size of aggregate.

Type I is the finest grade and primarily used in low speed traffic areas.

Type II aggregate is larger than Type I and is used in areas with moderate to high traffic.  This is the most common type used in the industry. Type II is used to seal, correct raveling and oxidation of asphalt, and provide increased skid resistance.

Type III is the largest of the aggregates and is used to correct more severe surface issues. It can help prevent hydroplaning and increase skid resistance under heavy traffic conditions.

Slurry Seal is mixed and applied by specialty equipment that is truck mounted. The slurry components are carried in the truck and then accurately mixed in the slurry mixing unit. The mixing and spreading of the Slurry Seal is accomplished in one continuous action. Slurry trucks are capable of spreading the width of a single traffic lane at one time. The surface is covered quickly and can be reopened to traffic within a few hours.

Chip Seal

Chip seal is a cost effective treatment commonly used to extend the life of existing pavement. This method provides a new wearing surface which can stand up to high traffic levels and is used on city streets, highways and county roads. Prior to the chip seal being applied, the road surface must be cleaned and all potholes patched. A distributor truck sprays hot liquid asphalt on the pavement and is closely followed by a chip spreader which covers the liquid asphalt with a single layer of uniformly sized aggregate chips.

The newly chip sealed surface is then rolled to seat the aggregate. Chip seal is a fast setting process which provides the least amount of traffic disruption. Caution must be taken to ensure drivers adhere to a reduced speed limit until the excess chips are swept.

Cape Seal

Cape seal combines both the chip seal and the slurry seal processes. The chip seal is allowed to cure and then is overlaid with slurry seal, generally within a week. The chip seal portion protects the sub-grade against moisture encroachment and provides elasticity to prevent cracking over the long haul. The slurry seal portion acts to secure the loose chips in place and provides a smoother surface than chip seal alone.

The cape seal application will extend the life of an existing asphalt surface with the durability of a chip seal while providing the smooth surface associated with the slurry seal application. This makes it ideal for residential areas along with large parking lots, industrial and commercial roadways, and high volume roads. Cape seal is one of the most durable surface applications available today.

Seal Coat

Seal coat substantially extends the life of pavement by sealing the top of the existing asphalt and protecting the upper layers from oxidation and wear. It also prevents water from penetrating the asphalt. The process seals small cracks rendering the surface more resistant to water damage. Seal coating improves the appearance of the asphalt giving a smooth, even black surface ready for painting.

Seal coat consists of a mixture of emulsified asphalt and water, and is applied directly to the pavement surface using a Seal coat machine and squeegees. Typically, this process is used in off-highway, lower traffic speed areas such as schools, parking lots, condominium projects, mobile home parks, etc.  Seal coat can extend the life of a paving surface for pennies on the dollar compared to repairing or replacing existing asphalt. Seal coat should be reapplied every four to five years.
