What is a slurry seal? Slurry seals are a mixture of asphalt emulsion, fine aggregate, and mineral filler that are used to protect and maintain pavement surfaces. This method of pavement preservation is commonly used in road construction projects to prevent premature pavement deterioration and to prolong the life of asphalt surfaces.
The design of the emulsified asphalt slurry seal should be a creamy-textured slurry that, when spread, will flow ahead of the strike-off squeegee and will flow down into the cracks in the pavement and fill them. Technical Bulletin No. 111, "Outline Guide Design Procedure for Slurry Seal", and publication A-105,

Slow-setting asphalt emulsion. Mix Design. None beyond the manufacturer's. A test patch may be needed to determine the proper application rate. Other Info. Fog seals are suitable for low-volume roads which can be closed to traffic for the 4 to 6 hours it takes for the slow-setting asphalt emulsion to break and set.
Slurry seal is a cold mix paving treatment containing aggregates, asphalt emulsion and water, while sealcoat is an emulsion containing liquid asphalt, mineral fillers and other additives. The main difference is that slurry seal has large aggregate. 2. When should I use slurry seal and sealcoat?
Emulsified Asphalt Slurry Seal Surface Treatment will be measured according to Section 90 by the square yard, all preparation, materials, and application, completed and accepted. Liquid asphalt material, aggregate, blotter material, water used for emulsion and preparation, sweeping and dust control are subsidiary to the work.
of a Premium Slurry Seal. 2 Description Premium Slurry Seal is a laboratory-designed mixture of polymer modified asphalt emulsion, aggregate, mineral filler, water and other additives accurately proportioned, mixed and uniformly spread over a properly prepared surface. Premium Slurry Seal can be used for both preventive and routine maintenance.
Slurry seal is a protective coating applied to asphalt surfaces to extend their lifespan and enhance their performance. It is composed of a mixture of aggregate, asphalt emulsion, and fillers. The application process involves spreading the slurry seal mixture over the existing asphalt pavement using specialized equipment.
A slurry seal is a homogenous mixture of emulsified asphalt, water, well-graded fine aggregate and mineral filler that has a creamy fluid-like appearance when applied. …
Emulsified Asphalt Slurry Seal A115 NOTICE It is not intended or recommended that this guideline be used as a verbatim specification. It should be used as an outline, helping user agencies establish their particular project specification. Users should understand that almost all geographical areas vary as to the availability of materials. ...
On the other hand, slurry seal is a mixture of asphalt emulsion, aggregate, water, and additives. It is less durable compared to micro surfacing but still provides a reasonable lifespan. Slurry seal is beneficial for low to medium traffic conditions and is often used as a preventive maintenance treatment to protect the pavement from …

A slurry seal is the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and additives to an existing asphalt pavement surface. A slurry seal is similar to a fog seal except the slurry seal has aggregates as part of the mixture. This combined mixture of the emulsion and aggregates represents …
Slurry Seals Slurry seal is a mixture of aggregate, emulsified asphalt, water and additives that are properly proportioned, mixed and spread over a prepared surface. A polymer-modified system can be used in the same application and will enhance one or more properties of the slurry to better meet a particular project requirement. Slurry seal is
The polymer-modified emulsified asphalt slurry seal shall be applied in a single layer as a homogeneous mat, adhere firmly to the prepared surface, and have a skid-resistant …

Use ISSA A105 and the following statements to inform decisions and provide support when writing a final specification for your slurry seal treatment: Determine if any changes to the specifications as stated are required for the asphalt emulsion and aggregate per AASHTO/ASTM specifications. State the storage limitations for the asphalt emulsion.
Read on to learn more about the features that define slurry seal types. Conventional. In its most basic form, conventional slurry seals consist of a mixture of emulsified asphalt and aggregate. Unlike traditional hot mix and warm mix asphalt, conventional slurry seals can be transported and applied at ambient temperatures.
After paving, the emulsified asphalt slurry mixture of the slurry seal can keep the road surface in good roughness, enhance the friction coefficient of the road …
Slurry seal is a thicker mixture that combines asphalt emulsion, aggregate (such as sand or crushed rock), water, and additives. It creates a dense, durable surface layer over the …

🔹 Role in Recycling Systems. Asphalt emulsion plays a crucial role in cold in-place recycling (CIR) and full-depth reclamation (FDR). In these processes, the existing asphalt pavement is milled, mixed with an emulsion, and then laid back down. This reduces the need for new aggregates and binders, conserving natural resources.
