Slurry Seal is a cold mix blend of high quality crushed aggregates, asphalt emulsion, water and mineral fillers, mixed together according to a pre-determined mix design from a laboratory. It is applied to an existing surface, such as surface treatment or pavements, that are still in fair to good condition, as a means of a cost effective...

What is Slurry Seal? zA thin maintenance treatment zA mixture of: • asphalt emulsion • graded aggregates • mineral filler • water • Additives zWhen placed on the pavement surface the mixture breaks and cures creating a new wearing surface. CURED FRESH Chapter 8 – Slurry Seals

Mix Design Methods for Slurry Seal / Microsurfacing

Description: Mix designs are an integral part of the overall performance of Slurry Seal, Microsurfacing and Chip Seals. For mix design of Slurry Seals and Micros, there are several recommended sources including ASTM D3910, ISSA A-105 & ISSA A-143, and MS-19 Basic Asphalt Emulsion Manual.In the lab, blending of the materials that are to be used in the field is done in varying proportions

Performance Review of Micro Surfacing and Slurry Seal

This paper concentrates on the process and mix design aspect of the quick set and quick traffic version of the respective applications as well as the performance to date across Canada. 2.0 PROCESS DESCRIPTION 2.1 Slurry Seal Processes Slurry seals are mixtures of mineral aggregates, cationic asphalt emulsion, water and additives mixed in

Calibration of Slurry Seal Micro Surfacing Equipment

• In Slurry Surfacing, all mix designs and formulations are based on the combined weight of dry aggregate and the weight of any mineral filler. To set the machines to a given mix design and to produce a consistent material, accurate information on the machine, feed rates or aggregate, emulsified asphalt, water, and additives is necessary.
