Tack Coat Guidelines

Asphalt binder is always used as a tack coat material when a geosynthetic pavement interlayer is placed. Asphalt binder should be considered for use for night work or in cooler weather. Asphalt binder is heated and applied at a much higher temperature than an emulsion. When the ambient temperature is above 85ºF, asphalt binder will easily

Asphalt Seal-Coat Treatments

Asphalt emulsions are applied at cooler temperatures (50 to 150 °F) than cutback or paving-grade asphalts. The water evaporating from the emulsion is environmentally safe. Emulsions can be made with a high viscosity to resist runoff on steeper sideslopes and road grades.

The Chemistry of Asphalt Emulsions

Asphalt emulsions, used in road construction and maintenance, may be defined as an homogeneous mixture of minute asphalt droplets suspended in a continuous water phase. These types of emulsions are usually termed oil-in-water (o/w) emulsions. Their preparation involves the use of a high speed, high shear mechanical device, such as a colloid mill.

Emulsified Asphalt – Pavement Interactive

Emulsions are used because they effectively reduce asphalt viscosity for lower temperature uses (tack coats, fog seals, slurry seals, bituminous surface treatments (BST), stabilization material). Emulsions are typically either anionic (asphalt droplets are negatively charged) or cationic (asphalt particles are positively charged).

Application Temperature Cheat Sheet - Asphalt Kingdom

Asphalt Emulsion Sealer. Asphalt emulsion sealer should only be applied if the ambient temperature is at least 50⁰F and rising. Pavement temperature should be at least 60⁰F and rising. It is not recommended to apply sealer during rainy or overcast days with high humidity. Moisture on the work surface would not allow the sealer to adhere to ...

Basics of Cold-Mix Applications with Asphalt Emulsions ...

Asphalt emulsion can be used in a conventional hot mix plant but require lower mix temperatures. The advantage is greatly reduced emissions and less hardening of the asphalt binder. The higher viscosity of the base binder at the mix temperature allows thicker films to be deposited on open-graded aggregates.

Asphalt Emulsion Properties - bitumen.globecore.com

Asphalt emulsion, like any other material, has a certain range of properties, which define the requirements to its production, storage and use. Viscosity. Viscosity is a very important performance parameter. If viscosity is low, the emulsion is not thick enough, while excessively high viscosity means the emulsion will stay on the surface ...

Asphalt

Emulsions have lower viscosities than neat (plain) asphalt and can thus be used in low temperature applications. After an emulsion is applied the water evaporates away and only the asphalt cement is left. Emulsions are often used as prime coats and tack coats.

CoolSeal - GuardTop

CoolSeal by GuardTop®. CoolSeal by GuardTop® is a high-performance, water-based, asphalt emulsion sealcoat designed to achieve lower surface temperatures through its lighter color and reflectivity. CoolSeal is applied like conventional sealcoats to asphalt surfaces to protect and maintain the quality and longevity of the surface.

Asphalt Emulsion - an overview | ScienceDirect Topics

Asphalt emulsions are water-continuous dispersions of fine asphalt droplets, typically 1–10 μm in diameter, manufactured with the aid of a colloid mill. The emulsions may contain between 40% and 80% asphalt by weight. The emulsions have significantly lower viscosity than asphalt itself, and so can be applied at lower temperatures.
