Slurry road surfacing is a cold mix paving method that may solve a variety of issues on streets, airfields, parking lots, and driveways. Consider slurry road surfacing to be high-quality asphalt surfacing. The primary elements needed to make slurry are aggregate, asphalt emulsion, and fillers, which are mixed together according to a mix design formula developed by a laboratory. Water is also added to make the mixture more workable.
Benefits of slurry road surfacing:
Slurry road surfacing is the most versatile pavement surface treatment system. It is also a unique bituminous mixture that can be used to meet the demands of a variably textured surface by filling cracks and voids, road surfacing on the surface weather-tight, and providing color and texture delineation all in a single pass. Some of the benefits of slurry road surfacing are as follows:
- Affordable
Slurry road surfacing is both inexpensive to install and extremely cost-effective to use. When choosing slurry road surfacing applications, contractors and clients benefit from recycled material and less effort.
- Prevention and preservation
Existing distress in older pavements, surface cracking, raveling, matrix loss, increased water and air permeability, and lack of friction due to flushing or aggregate polishing can all be rectified with a slurry treatment.
Waterproofing is also accomplished, which prevents future damage. An all-weather, long-lasting surface is created, providing skid resistance and improved driver handling characteristics.
- Aesthetic Value
Existing pavement acquires a new wearing surface of uniform black color or texture with a single easy application. Increased property value, marketing possibilities, and buyer acceptability all result from improved aesthetics.
Slurry road surfacing makes thoroughfares, shopping center parking lots, and other public or commercial pavements more desirable and eye-catching.
When to use Slurry road surfacing?
Slurry road surfacing is often applied intermittently or cyclically. Location, weather, traffic loads, and pavement conditions are all considered while deciding whether or not to apply slurry road surfacing. Slurry road surfacing treatment is often used to roads that have little to moderate distress, no rutting, and generally narrow crack widths, and where a slurry road surfacing solution would help extend the life of the pavement until resurfacing is necessary.
Typically, cyclical slurry road surfacing treatments would be applied to roads every five to seven years.
How does slurry road surfacing work?
The asphalt emulsion and aggregates are mixed together and applied with a specially designed truck known as a “slurry truck.”
Slurry trucks include many compartments that carry aggregate (fine crushed rock), water, polymer modified emulsion, and other additives that are blended in an on-board mixer. Within the constraints of a box attached to the back of the truck, the slurry mixture runs out of the rear of the vehicle and onto the pavement.
The box’s purpose is to spread the slurry mixture across the pavement. Workers with squeegees trail behind and help distribute the mixture, correct sections that aren’t adequately coated, and keep the mixture off concrete enhancements like gutters.
