Woodward (109) used the Vialit Plate Test and the Instron Adhesion Pull-Off Test (INAPOT) along with the NET to predict the adhesion property in the laboratory. The INAPOT was developed as a method to quantify the effect of steady load and temperature conditions on the adhesive bond per- 41 formance of aggregate prisms pressed into a pot of bitumen (109).

Optimisation of bitumen emulsion properties for ballast

The ballast used for this study was granite aggregate sourced from Bardon Hill quarry in Leicestershire, United Kingdom (23, 26).Due to the dimensions of the test apparatus, two scaled (approximately one third scale) gradations (clean and fouled ballast) were used as

Adhesion with bitumen The aggregates used in bituminous pavements should have less affinity with water when compared with Durability The property of aggregates to withstand adverse action of weather is called soundness. The aggregates are subjected to the physical and chemical action of rain and bottom water, impurities there-in and that of atmosphere, hence it is desirable that the road

crushing strength test on aggregates

The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – 12.5mm, 10mm and 2.36mm. Procedure to determine Aggregate Crushing Value i) The aggregates passing through 12.5mm and retained on 10mm IS Sieve are oven-dried at a temperature of 100 to 110 o C for 3 to 4hrs.

Freeze

Freeze-thaw (FT) cycles and moisture susceptibility are important factors influencing the geotechnical characteristics of soil-aggregates. Given the lack of published information on the behavior of cement-bitumen emulsion-treated base (CBETB) under environmental conditions, especially freezing and thawing, this study investigated the effects of these additives on the CBETB performance.

WO2006131727A1

The amount of small particles of aggregate in a mass of aggregate is reduced by causing a binder, for example bitumen, to contact the small particles and preferentially adhere to them, thereby causing groups of small particles to coalesce and thereby define larger particles . As a result, the amount of small particles in the mass is reduced thereby allowing the mass of material to be used in
