ASPHALT PAVEMENT CRACK SEALING

& ROUTE & SEAL


STOP POTHOLES IN THEIR TRACKS...SEAL THE CRACKS!


Progression of a pavement crack.

STAGE 1

Minor Crack Forms

STAGE 2

Water Worsens Crack

STAGE 3

Chunks Start Popping

STAGE  4

Potholes Prosper

Water is the most destructive element to asphalt.



As part of a pavement maintenance system, crack sealing can significantly reduce pavement deterioration by preventing water penetration into the base and sub base layers


Crack sealing will not improve initial asphalt rideability, however, the benefits are realized in three to five years when it becomes quite obvious that the asphalt has not deteriorated any further.

​​​​​​​

At a time when manpower is shrinking, along with the funds to support road maintenance, crack sealing stands out as an economical maintenance technique.  The overall success of pavement maintenance programs that include crack sealing, combined with the generally low cost, make crack sealing a highly desired technique by successful property managers and owners.  Crack sealing provides the most cost-effective use of dollars over time compared to other pavement maintenance techniques.​​​​​​​   

Crack sealing is a proven technique that works. This is the reason our governments fund crack sealing programs every year on our roads, simply because IT WORKS and IT'S COST EFFECTIVE!

HOW CRACK SEALING WORKS

OUR PROCESS


Crack sealing begins with surveying the areas to be crack sealed. Once an area is deemed to be a good candidate for crack sealing, the cracks are then cleaned out with an asphalt pavement router, cleaning the crack and creating a reservoir for the sealer.  


The sealer is then heated inside a kettle to a temperature of 185°C (365°F).  Once the sealer is melted, it is then neatly injected into the crack.  The crack sealer then cools and contracts flush with the pavement, hardening almost instantly back into its rubber form.  It is ready to drive on in a couple minutes.  This process is also referred to as route and seal.

WHAT KIND OF CRACKS CAN BE SEALED

CRACKS THAT CAN'T BE SEALED

ALIGATOR CRACKING / SPIDER CRACKING


Pavement selection is very often overlooked in determining the success or failure of a crack sealing program.  If the road has alligator cracking, poor sub base drainage or structural damage, crack sealing will not solve the problem.  In these cases the damage is too severe. If you try to save pavement with too much cracking, you will be disappointed with your efforts.  In which case, repaving is the only alternative.


BE WEIRY OF COMPANIES WHO CLAIM THEY CAN REMEDY THESE AREAS WITH CRACK SEALER.  THIS WILL ONLY  LEAD TO DISSAPOINTMENT AND MORE EXPENSE.

CRACKS THAT CAN BE SEALED

TRANSVERSE CRACKING / BLOCK CRACKING


The best candidates for crack sealing is asphalt that is beginning to form cracks. You undoubtedly can extend the life of this asphalt.  More sealant is not always better.  The new sealants are not designed to be "road glue." They are very sticky and have tremendous bonding power but they are not made to "hold the road together." Crack sealing has one objective: to prevent water from getting below.  Sealing buys you time and saves you money by delaying the expense of major reconstructive pavement work.
