Why do Asphalt/Concrete Pavements Crack?
 
Varying Climatic Conditions, comprising of freeze/thaw cycles, cause asphalt/concrete pavements to contract/expand, producing cracks.
Aged Asphalt becomes oxidized and brittle. This creates a hard and brittle surface inducing cracking, resulting in an exposed base. An exposed base leads to debris water and penetration, which creates base deterioration.
Heavy Traffic use has an adverse effect on the pavement surfaces. Compacted travel lanes apply pressure to the pavement surfaces, compelling the asphalt/concrete to move and crack.

Benefits of Crack Sealing
 
Minimizes Asphalt/Concrete life cycle costs
Prolongs Pavement life
Prevents vital loss of pavement base from further deterioration
Permits easier pavement maintenance
Prevents damage to traffic vehicles
Enhances Pavement appearance

Crack Routing
 
A mechanical router routes the cracks in the asphaltic/concrete pavement to remove the deteriorated material.
Routing the cracks creates a vertical groove/pocket in the pavement to permit more sealant into the crack, allowing expansion of the sealant during colder climates.
Removal of oxidized and deteriorated material produces a fresher base, permitting a stronger bonding surface for replacement material.

Crack Cleaning & Preparation
 
The routed cracks are cleaned and dried with a Hot Air Compressed Lance.
Lancing removes moisture and debris from the cracks.
A hydraulic air compressor is used in residential areas to reduce noise levels.
Cleaning cracks by Lancing results in a more compatible bonding surface for Material Application

Material Application
 
A Hot Rubberized Material is applied to the Routed and Cleaned cracks.
The Hot Rubberized material is pumped from an oil-jacketed kettle through a pumping system.
An Application Wand is used to apply the Hot Rubberized Material by pumping it directly into the Routed and Cleaned cracks.
The tip of the wand is placed close to the bottom of the Routed and Lanced groove/crack to ensure uniform application.
Wand Tips are interchangeable to accommodate different route sizes.
The manufacturer's recommended application temperature is used to produce maximum bonding of the material.
Material used conforms to the latest Government specifications.
The bonded material remains flexible and resilient to adapt to varying climatic conditions.
Under normal conditions, the applied and bonded Hot Rubberized Material sets within 10 minutes to resume traffic flow.

Traffic Control
 
In high traffic areas, if necessary, a light dusting material is applied to the Applicated Hot Rubberized Material.
Damage by traffic can be prevented by this method. Signs, barricades, arrow boards, flag persons and other protective devices are implemented to safely direct traffic and protect the workers and the public.
