ABOUT ASPHALT EMULSIONS
Asphalt emulsions are stable, homogeneous mixtures of minute asphalt droplets suspended in a continuous water phase. The stability of the oil and water dispersion is achieved by a colloid mill which shears the asphalt into tiny droplets while the chemical surfactants in the water phase (commonly know as soap) stabilizes the system chemically by imparting a charge to the asphalt particles. The emulsions are categorized by the nature of this charge as cationic, anionic and nonionic.

APPLICATION
Asphalt emulsions are used in cold processes for road construction and maintenance. Emulsions are classified on the basis of how quickly the asphalt droplets will re-coalesce (break and setup). The terms rapid set (RS), medium set (MS), quick set (QS) and slow set (SS) have been adopted to classify the emulsions. A letter “C” in front of the classification denotes cationic systems while the absence of a letter in front of the classification denotes anionic systems. Nonionic systems are used mostly in roofing and specialty applications and are not used in road construction and maintenance.

Rapid set (RS) emulsions are used in chip seals, medium set (MS) emulsions are used in road aggregate mixes such as those used in open graded pavements, quick set (QS) emulsions are used in slurry mixes with fine aggregates as a finishing coat referred to as slurry seal, and slow set (SS) emulsions are used in a sprayed on layer as fog seal or tack coat. Slow set (SS) emulsions can also be mixed with fine aggregate such as slate and clay and used as seal coats.

Products
The following emulsions are manufactured by Telfer Companies in Martinez, California.

Dust Palliatives
About
Dust palliatives are the agents applied to various road surfaces to prevent dust clouds and their environmental impact.

How It ’s Used
Most dust palliatives are spread directly to the road surface. Preparation is minimal. Depending upon road usage and weather conditions, a maintenance plan with subsequent applications is recommended.

Products
Lignins
Ligneous or “lignins” (also known as tree sap) are used in dust control and surface stabilization. The product is derived the from the lignin that naturally binds cellulose fibers together to give trees and plants firmness. Commercial lignin products meet the specifications of the U.S. Forest Service Administration, General Service Administration and local and regional government standards.

Advantages
-Creates a denser, firmer road cap
-Water-soluble
-Eco-friendly and non-toxic
-Non-corrosive
-Easy to handle and apply
-Cost-effective
-Requires no special equipment or clothing

Coherex®
Coherex has been used for 40 years in many different applications and industries for controlling dust and as a wind erosion agent. It is a petroleum resin-based non-volatile emulsion consisting of approximately 60% semi-liquid natural petroleum resins and 40% wetting agents. Coherex leaves a cumulative residue of the resins deposited on the soil particles, so only occasional, light re-treatment is required.

Advantages
-Stable
-Long shelf life
-Concentrated
-Can be freeze-stabilized for winter storage
-Non-toxic
-Non-flammable
-Non-combustible
-Non-corrosive

Magnesium Chloride
Magnesium Chloride is a salt compound comprised of magnesium and chlorine and is used for controlling dust on a variety of road types.

Advantages
-Eco-friendly
-Leaves no residue
-Colorless and odorless
-Hygroscopic (attracts moisture)
-Can be used down to 5° F

Cutbacks
About

An asphalt cutback consists of an asphalt cement blended with a petroleum solvent resulting in viscous liquid. The solvents used in the production of asphalt cutbacks are usually quite volatile. On the basis of relative speed of evaporation, asphalt cutbacks are classified into rapid-curing, medium-curing and slow-curing grades. Some grades are not allowed for use in certain states.

How It ’s Used
Asphalt Cutbacks are applied by spreader truck. It is not recommended to use asphalt cutbacks with tack pots or spread with a hand wand.

Advantages
-Relatively inexpensive "road oiling" treatment
-Effective as dust control agent
-Useful as prime coat

Geotextiles
About
Geosynthetics are a specific, engineered response to a specific problem; how to enable landforms to withstand severe and erosive forces of nature.
How It ’s Used
-Asphalt road base support
-Soil stabilization
-Soil reinforcement
-Soil separation
-Soil retention
-Filtration
-Revegetation
-Erosion prevention/protection

Advantages
-Geosynthetics are engineered specifically as a cost-effective solution for geotechnical and hydraulic applications.
-Geosynthetics are easy to install
-Geosynthetics are effective in permanent civil structures.
-Geosynthetics reduce extraction and depletion of sands and aggregates, and are environmentally friendly.

Paving Fabrics
About
A strong layer of fabric is applied under asphalt to minimize surface water infiltration and prevent existing cracks in the road from surfacing.

Benefits
-Provides moisture barrier
-Absorbs stress
-Effectively retards reflective cracking

How It ’s Used
Paving fabrics are primarily applied with a mounted attachment on a tractor onto a hot asphalt tack coat, then overlayed with a minimum 1.5 inches of asphalt mix.

Advantages
-Paving fabrics create a barrier against water intrusion to the existing road surface
-Extend road life
-Used throughout the U.S. as way to cost effectively maintain road surfaces

Products
We carry a variety of paving fabric solutions.

Paving Grids
About
There are two types of Paving Grids: Reinforcing Grids and Waterproofing Grid Composites.
Reinforcing Grids are designed to provided tensile strength to a new overlay
Waterproofing Grid Composites are designed to provide tensile strength and waterproofing to a new overlay

How It ’s Used
Grids are applied similarly to paving fabrics. A tractor mounted with an attachment applies the grid on a hot asphalt tack coat. The asphalt overlay recommended minimum thickness is 2".

Advantages
-High tensile strength
-Provide structural support to applied surface
-Waterproofing Grid Composites provide moisture barrier

Products
We carry a variety of Paving Grids solutions.

TruPave® Engineered Paving Mat
About
TruPave is a hybrid fibre glass and polyester non-woven mat, engineered to be millable and recyclable, with high tensile strength at low strain. TruPave is stable up to 495 F thus suitable for elevated paving temperatures.

How It ’s Used
TruePave can be used in any application where a typical paving fabric interlayer would be used, such as a mill and fill with a leveling course or directly over existing pavement in hot tack asphalt. TruPave mats are laid down then followed by an Hot Mix Overlay, where increased immediate low-strain tensile, high temperature stability, millability and recyclability are needed.

Advantages
-Millable and recyclable
-High tensile strength
-Stable performance
-Non-stretching
