Key bitumen types for road applications including paving grades, cutback bitumen, and bitumen emulsions.

Bitumen and Bituminous Materials in Detail

 · Traditionally bitumen is regarded as a colloidal system which consist of high molecular weight asphaltene micelles & are dissolved in lower molecular weight oily medium called as maltenes. According to structure bitumen can be classified in two type :-1) SOL Type or solution type. 2) GEL Type or gelatinous type.

A Basic Introduction to Rheology

asphalt or bitumen much more temperature dependent than low viscosity fluids such as water. To measure shear viscosity using a single head (stress controlled) rotational rheometer with parallel plate measuring systems, the sample is loaded between the plates at a known gap (h) as shown in Figure 2. Single head rheometers are

by changing the mass of bitumen added, whilst keeping the mass of rubber constant. Quantities of 10, 20 and 40g bitumen were added to 5g of rubber to give percentage of rubber as 33, 20, and 11% respectively. Sets of seven beakers were prepared for each rubber-bitumen ratio and within each set, each beaker was allowed to cure for a different time.

EMULSION BASICS

seize or shear the asphalt emulsion. • DO NOT apply severe heat to pump packing glands or pump casing. The pump may be damaged and the asphalt may become even harder. • DO NOT dilute rapid-setting grades of emulsified asphalt with water. Medium and slow setting grades may be diluted, but always add water slowly to the asphalt emulsion.
