Asphalt emulsions can be used for almost any type of pavement application. They can be used for preventive and corrective maintenance on both asphalt and concrete pavements, stabilizing and reclaiming bases, building structural pavements and recycling worn out pavements. Recycling with asphalt emulsions is an environmentally attractive way to ...

Jun 05, 2018  Concrete emulsions are a key part of pavement preservation, maintenance, and rehabilitation. The Concrete Emulsion Manufacturing Association (AEMA) has hired the University of Arkansas to develop three certificate programs around asphalt emulsion. Two are complete and available, while the third is under development. Here are some links:

Collect weighmaster certificates and “weigh-back” slips for trucks delivering asphaltic emulsion or liquid asphalt. When additional water is added to asphaltic emulsion, calculate the amount to be deducted from the original weight, using the ratio in the original mix of asphaltic emulsion to water.

impediment to the acceptance and application of FSB and asphalt emulsions beyond the testing phase. GHG emission reductions are generated from producing and applying FSB and asphalt emulsions versus HMA as follows: • FSB and asphalt emulsions consist of 50% less liquid asphalt/bitumen by weight and 2.5%

Bitumen Emulsion Applications - GlobeCore Bitumen Emulsion.

Tack coat. Tack coat is the most common application for bitumen emulsion. A thin emulsion layer is applied by spraying it to ensure secure adhesion of the asphalt mix to the underlying layers. This layer is required for most roads. There are several types of tack coats. For instance, slow breaking emulsion with 55-60% bitumen can be applied.

Most emulsions used for seal coats are applied at 120 ° F to 160 ° F. When using asphalt cement, application temperatures may range from 275 ° F to 375 ° F. Application temperatures for cutback asphalts may range from 125 ° F to 275 ° F. Cutbacks should be shot 25 ° F to 50 ° F below their respective flash point.

When asphaltic emulsions are used as a tack coat for asphalt concrete, the application rate is specified in terms of a residual rate. The residual rate is the amount of bituminous material that remains on the pavement after water and emulsifying or stabilizing agents evaporate; it is not the application rate from the distributor truck.

Asphalt Emulsion Application. Concrete Emulsion Application. Concrete emulsions can be used for almost any type of pavement application. They can be used for preventive and corrective maintenance on both asphalt and concrete pavements, stabilizing and reclaiming bases, building structural pavements and recycling worn-out pavements.

Asphalt emulsion does not require a petroleum solvent to make it liquid and in most cases asphalt emulsions can be used without additional heat. Both of these factors contribute to energy savings. Additionally, asphalt emulsions offer great flexibility in their application since they offer the end-user a great variety of characteristics not ...

Further, the certificate will indicate the non-volatiles (solids) content and ash content of ... Concrete emulsions shall be diluted one part asphalt emulsion to 5 parts potable ...

application. • DO NOT permit the asphalt emulsion to be heated above 185ºF. Elevated temperatures evaporate water, changing the characteristics of the asphalt emulsion. • DO NOT let the emulsion freeze. This breaks the emulsion, separating the asphalt from the water. The result will be two layers in

The asphalt particles are surrounded by the ionic charge, which causes the droplets to repel each other and stay suspended in the water. All asphalt emulsions are designed to eventually break, or revert to asphalt and water. Some emulsions break by chemically destabilizing the surfactant, others by a simple evaporation of the water.

Introduction to Concrete Emulsion • Residue from the vacuum distillation of crude oil • Crude oil contains 1-60% asphalt depending on the source • Not all refineries produce asphalt • 36 million ton asphalt used in USA each year • 31 million ton used in road construction, rest mostly in roofing • Concrete • The Chemistry of Emulsions

Tack Coat Guidelines

The contractor has the option of using any emulsion or asphalt binder that conforms to the Standard Specifications for a tack coat. For emulsions, the rate of setting is dependent upon the type of emulsion, the amount of water added, the type and concentration

2.5% to 3% polymer solids by weight of asphalt. The polymer modified emulsion shall be compatible with the mix design developed for the conventional slurry seal. Each shipment of emulsified asphalt shall be accompanied by a certificate of analysis or certificate of compliance from the manufacturer.

temperature of the asphalt emulsion during application shall be maintained between 120 -160°F (48.9 – 71.1 °C). 12 Material Storage and Handling Concrete emulsion stored on the job site must be agitated and heated using the distributor prior to use. Stored emulsion shall be inspected by the contractor for suitability prior to use on the project.
