Generically, a slurry is a thin mixture of a liquid, usually water, and any of a number of finely divided substances, such as cement, plaster or Paris, or clay particles. The term is also used to refer to the viscosity of a mixture. Commercial Slurry SealSlurry 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 preventative maintenance. It reduces deterioration by sealing, prevents further oxidization, corrects raveling and provides or replaces a high degree of skid resistance. Slurry Seal is applied with a spreader box, which is connected to the slurry mixing unit. The box is the width of a single lane, allowing a uniform spread of material in a single pass. Crews ahead of the unit set up traffic control, and sweep the surface before applying the slurry seal. Operators of the units monitor the mixing and application. After a short curing time traffic will be allowed to resume use of the freshly rehabilitated lane. There are three types of Slurry seal commonly used, each using a different size of aggregate;
  • Type I- Slurry Seal (Fine Aggregate,1/8" max) Used for lower traffic volumes and maximum crack penetration

    Recommended application rates are 4.3-6.5 kg/ m 2

  • Type II-Slurry Seal ( General Aggregate,1/4" max) Most commonly used slurry. Good for moderate to high volume roads

    Recommended application rates are 6.5-10.8 kg/ m 2

  • Type III- Slurry Seal ( Coarse Aggregate ,3/8") Used for high volume roads and heavier traffic.

    Recommended application rates are 9.8- 16.3 kg/ m 2
