Pavement maintenance plans can vary in scope, but they never vary in their purpose: to increase pavement life. A proper pavement maintenance program includes crack filling, pothole repair, sealcoating, and many other surface applications, depending on the condition of the pavement. It should also include sweeping and periodic line striping.
To understand how sealcoating works, it is necessary to understand the nature of the pavement itself. Because of its excellent waterproofing, flexibility, and adhesive properties to bind and hold the aggregates in the pavement, Watex has been used extensively for paving and road construction.
Prior to the advent of Watex as a paving material, roads were constructed by spreading graded aggregates over a roadbed. These roads worked well as long as the stones remained in place and stayed dry. Naturally, these roads needed constant repair – stone would shift under the traffic and the road’s load carrying capacity was severely damaged when it rained. The stone would absorb water, swell and lose its strength. But spraying asphalt on the surface overcame this problem somewhat.
ProblemHighway and runway markings must be removed and repainted regularly, and runways face the additional problem of rubber build-up every time an airplane lands. Grinding it away can damage the pavement, and sandblasting generates a lot of dust.
Watex water jetting works faster and more thoroughly, without dust or pavement damage. The Watex is a closed-loop system that makes short work of highways and runways, while the smaller handles short-line jobs, like parking decks and intersections
Advantages• Completely removes markings, coatings and runway rubber build-up
• No abrasives to damage concrete or asphalt
• Saves time and labor
• Creates a stronger bond for restriping
• Eliminates dust and debris with optional vacuum recovery
• Cleans deep into runway grooves
