Making Slurry Seal

Slurry is made in specially designed RoadSaver II or RoadSaver IIIG equipment manufactured by Rayner Equipment Systems. This equipment carries a quantity of unmixed materials that are blended together in a continuous flow pugmill. The use of this technology is made quickly and accurately at the project site. Mixing and spreading are accomplished in one continuous operation, with the surface being ready to be reopened to traffic/pedestrians within a few hours or less.

Explanation of laying slurry seal with RoadSaver

Applying Slurry Seal

Slurry Seal is applied to an existing surface by means of a spreader box linked to a RoadSaver slurry mixing unit. Slurry is introduced into the spreader box, which then lays down the slurry coating as the mixer/spreader is driven forward. The spreader box is capable of spreading the slurry seal over the width of a traffic lane in a single pass, and is constructed so that close contact with the existing surface is maintained. This insures uniform application of the new coating on a variety of configurations encompassing various crown shapes, super elevated, and shoulder slopes. Trained operators continually monitor the automatic mixing procedure. Other personnel clean the surface before slurry application, barricade and street/area, inspect the operation in progress for uniformity, clean metal utility covers after application and complete slurry seal spreading in any area not accessible to the spreader box.

Micro Surfacing

Micro Surfacing is a mixture which is aesthetically similar to slurry seal and is applied in almost the exact same fashion. Micro Surfacing, is however a superior product to slurry seal in that it utilizes higher quality aggregates and increased polymers in its mix designs and applications. Micro can be produced utilizing any of the three aggregate types as shown on the diagram. Due to slight chemistry modifications of the micro-surfacing emulsion, better quality aggregates and increased polymers; micro-surfacing can be laid in slightly thicker applications, multiple layers and can be opened to traffic much faster than slurry seal. The increase in polymers and application thickness allow micro-surfacing to provide an even tougher longer lasting surface than a slurry seal. The tough characteristics of micro and the accelerated dry time also allow micro-surfacing to be placed at night. Maximizing the opportunity to work around peak hours of traffic and business.
