Just how slurry seal is made
Slurry is made in the specifically created RoadSaver II Microsurfacing equipment manufactured by CPM. This equipment lugs an amount of unmixed products that are blended together in a continuous circulation pugmill. The use of this technically sophisticated equipment guarantees a smooth continually consistent combination.
Slurry is made rapidly as well as accurately at the task site. Blending and also spreading out are accomplished in one continuous operation, with the surface area being ready to reopened to take a trip within a few hours. Revealed below are the materials and also percent amounts for a type I slurry seal:
accumulated ~ 77 %.
emulsified asphalt oil ~ 12– 16 %.
water ~ 5– 10 %.
aluminum sulfate (or some additive)~ 1/2– 2 %.
Number 1. Slurry Seal type I mix layout.
When the slurry seal is cured, the only parts left are the aggregate and also asphalt oil. The water is used just to assist in collaborating with the mix as it is used. Aluminum sulfate, portland cement, lime, or other ingredients are healing agents that either speed up or reduce the curing process.
Below shows the results that different agents carry the mix.

Latex is used to enhance the tensile toughness (or destroying strength) of the slurry when is it treated. This assists the slurry stand up to fracturing or dividing as website traffic presses as well as presses on the asphalt sidewalk. Carbon Black is a cosmetic additive only. It is there making the last slurry area a darker black.
just how slurry seal is used.
Slurry Seal is put on an existing sidewalk surface using a spreader box linked to the RoadSaver II slurry mixing device. Slurry is introduced right into the spreader box, which after that sets the slurry layer as the mixer/spreader is driven forward.
The spreader box is capable of spreading out the slurry seal over the width of a website traffic street in a solitary pass, and I built to make sure that close contact with the alreadying existing area is kept. This insures consistent application of the brand-new coating on a variety of setups encompassing different crown shapes, super-elevated and shoulder inclines.
Trained drivers continuously keep an eye on the automated mixing treatment. Some personnel wash the surface area slurry applications, blockade the road, check the operation in progress for harmony, tidy metal utility cover after application and complete slurry seal dispersing in any area inaccessible to the spreader box.
