asphalt emulsion viscosity

Standard Practice for Viscosity-Temperature Chart for

11 The viscosity-temperature chart covered by this standard is a convenient means of plotting data for estimating the viscosity of asphalt binders at any temperature within a limited range Conversely, the chart may be used to ascertain the temperature at which a desired viscosity is attained.

Asphalt Processors Inc

Cutback Asphalts can contain anything up to 50% kerosene or gasoil Asphalt emulsions contain 0-2% Thus there is a significant saving in the use of valuable white fuel products In a cutback the solvent is added merely to reduce viscosity of the Asphalt to a level where it can be poured and sprayed.

Temperature-Viscosity Data on Asphalt Cements

TEMPERATURE

Cutback asphalt A cutback asphalt is a combination of asphalt cement and petroleum solvent Like emulsions, cutbacks are used because their viscosity is lower than that of neat asphalt and can thus be used in low temperature applications After a cutback is applied the solvent evaporates away and only the asphalt cement is left.

• Supplied in grades depending on its consistency/viscosity • For emulsions viscosity is defined by tests like penetration and softening point • The choice of asphalt depends on the end use • Most asphalt grades can be supplied in emulsion form.

Asphalt Emulsion CSS-1h

Asphalt Emulsion CSS-1h is a cationic slow setting asphalt emulsion produced by the patented SMEP process The base asphalt for emulsification is derived from specially selected crude oils via carefully controlled refining process.

Use of Asphalt Emulsions

Figure 8-20—Tars obtained from distillation of bituminous coal The viscosity grades range from 1 (least fluid) to 3 (most fluid) Use of Asphalt Emulsions Emulsions are used for surface treatment, road and plant mixes, and crack and joint filling The mixing grades can be mixed unheated with damp aggregate.

EMULSION BASICS

slowly to the asphalt emulsion Never add the asphalt emulsion to a tank of water when diluting • DO NOT re-circulate emulsified asphalts for too many cycl They tend to lose viscosity when subjected to excessive pumping Also, air bubbles may become entrained which would render the emulsion unstable.

CQS-1hP Product Data Sheet

CQS-1hP Product Data Sheet Description and Physical Properties CQS-1hP is a cationic, polymer modified asphalt emulsion designed for use in slurry seals The slurry seal process mixes the emulsion, aggregate and additives in a specially designed machine, which also places the mixture The polymer improves durability for more demanding locations.

What is the difference between cutback, bitumen and

Apr 01, 2017· Bitumen, Emulsion and Cutback are Paving Binders That Are Used in Flexible Pavements * Bitumen is Obtained From Refining Process (Fractional Distillation) of Crude Oil (A Petroleum Product) and is Widely Known For Its Adhesive and Water Proofing.

Tests Applied on Bitumen

Viscosity Tests on Bitumen Asphalt The viscosity test measures the viscosity of an asphalt Both the viscosity test and the penetration test measure the consistency of an asphalt at some specified temperatures and are used to designate grades of asphalts.

Asphalt Emulsion CRS-2

Asphalt Emulsion CRS-2 is a cationic rapid setting asphalt emulsion produced by the patented SMEP process The base asphalt for emulsification is derived from specially selected crude oils via carefully controlled refining process.

For a more in-depth discussion on asphalt emulsion chemistry, the differences between anionic and cationic emulsions, and how the chemistry affects the break and cure, refer to Asphalt Emulsion Cutback Asphalt Cutback asphalts are mixtures of asphalt cements and solvents Solvents lower the viscosity.

Overview of Asphalt Emulsion

The use of asphalt emulsions began in the early part of the 20th century Today 5% to 10% of paving-grade asphalt is used in emulsified form, but the extent of emulsion usage varies widely between countri The United States is the world’s largest producer of asphalt emulsion The advantages of asphalt emulsion compared to hotRead More.

FIELD GUIDE TO EMULSIONS

asphalt emulsions Thus, a CSS-1H is a cationic slow set emulsion with a relatively low asphalt emulsion viscosity made with hard base asphalt Do asphalt emulsions have any uses around the home? Driveway sealers, roofi ng repair materials, caulks and mastics may contain specially formulated asphalt emulsions.

TRANSPORTATION RESEARCH

With viscosities in the range 05-10 Poise at 60°C, asphalt emulsion is of considerably lower viscosity than asphalt itself (100-4,000 Poise), allowing it to be used at lower temperature Low-temperature techniques for construction and maintenance reduce emissions, reduce energy.

Asphalt Emulsion

Emulsions are used because they effectively reduce asphalt viscosity for lower temperature Generally, asphalt emulsions appear as a thick brown liquid when initially applied but when the asphalt starts to adhere to the surrounding material (eg, aggregate) the color changes from brown to black.
