QS emulsions work well with fine aggregates but are designed to break faster than SS emulsions QS emulsions are used in micro-resurfacing and slurry seal designs The quick break allows for faster opening to traffic High Float Emulsions An “HF” that precedes the setting time designation indicates a High Float emulsion.

The additives influence the mix time and set time Advantages Microsurfacing can be placed in a thicker layer than a slurry seal and, therefore, can be used to fill wheel ruts and correct minor leveling problems It has a quicker cure time so traffic can be allowed on the road sooner than a slurry seal.

This stuff sealed my 1 year old driveway just great! It was my first time sealing an asphalt drive, but after watching the video a few times, I was able to complete the job quite well Only time will tell how long it lasts, but, for now it looks terrific! Make sure to get the brush to outline edges, and the squeegee to spread the sealer on.

Cal-Seal accelerator also decreases slurry density, thickening time and overall ‘final strength’ When blended with Portland cement, Cal-Seal 60 accelerator is perfect for shallow wells and for surface applications that require short setting times and rapid strength development.

The slurry seal can be placed anytime after the chip seal has set and cured What type asphalt should be used? A liquid asphalt, such as a Rapid Setting Emulsion (RS-1,2 or CRS-1,2 includes modified), Cutback asphalts in some areas depending on EPA regulations which would include RC-250, 800 or 3000, are normally used.

Dec 05, 2017· New asphalt needs time to cool before you allow traffic on it, which is known as “asphalt curing time” Unlike concrete which “cures” in the first few days of installation, new asphalt can be driven on as soon as it’s rolled and cool Too many variables exist to give an exact amount of time your parking lot or road will be closed.

RESURFACING WITH SLURRY SEAL Frequently Asked Questions Q What purpose does Slurry Seal Serve? A Slurry Seal is a think asphalt overlay/sealer that will fill in slight imperfections and give your street a uniform color and textureMost importantly it seals the street, thus preventing the infiltration of water, which is the most frequent cause of pavement failure.

Types of Slurry Emulsions of varying composition and setting times are mixed with any one of three grades of aggregates to create slurry seal mixes for specific purpos Aggregate types are I (fine), II (general), and III (coarse) Fine aggregate mixtures are used for maximum crack penetration and sealing in low-density/low-wear traffic areas.
