A modified asphalt particle having a high softening point, a preparing method thereof and applications of the particle are disclosed. The diameter of the particle is not more than 120 [mu]m. The particle includes a core made of base asphalt and a shell formed by a modifying agent, and includes 7-9 parts by mass of the core and 1-3 parts by mass of the shell.
Straightrun bitumen is modified with polymer to increase the softening point: both plastomer APP and elastomere SBS are used. With SBS, the elastic recovery is improved. Durability is over 25 years and depends upon exposure. Mainly cold and soft application are performed (no or less fumes than hot application). Recycling is possible.

The softening point of a bituminous material can be defined as the temperature at which this bituminous material further softens after its arbitrary softness point is reached. There are various methods that are helpful in determining the softening point of a bituminous material. They are as follows: Vicat method as per ASTM D1525 or ISO 306
Nov 09, 2015 · EXPERIMENT NO. 12 SOFTENING POINT OF BITUMEN (RING-AND-BALL APPARATUS). [ASTM Designation: D 36-76, AASHTO Designation: T 53-89]SOFTENING POINT: Softening Point of Bitumen. The softening point is defined as the mean of the temperatures at which the bitumen disks soften and sag downwards a distance of 25 mm under the weight of a steel ball.
Penetration Grade Bitumen is a standard bitumen usually used as a Paving Grade Bitumen essential for road construction and for the production of asphalt pavements with superior properties, and it's very important once it bounds the aggregates and creates a unique cohesion and stability to the bituminous mix.. This grade of Bitumen is mainly used in the manufacture of hot mix asphalt for bases .
The heated Penetration Grade Bitumen under controlled environment is blown with air which controls the oil content in the Bitumen while it is oxidized. The different grades produced for suited applications are distinguished by two numbers to indicate the mid points of their softening point and penetration ranges.
Jan 02, 2019 · Introduction Bitumen has a number of applications but it is mainly used either directly or indirectly in the construction and maintenance of roads. It is estimated that 90% of its applications is in the road construction and maintenance industry. Typical bitumen types for road applications includes paving grades, cutback bitumen, and bitumen emulsions.

Softening Point The softening point is defined as the temperature at which a bitumen sample can no longer support the weight of a 3.5-g steel ball. Although it is commonly used in Europe, it is mostly used for roofing asphalts in the U.S. Basically, two horizontal disks of bitumen, cast in shouldered brass rings (Figure 1), are heated at a .
Nanofill-15 has little effect on softening point; by adding 7% nanofill, softening point increased by only 3%. In contrast, Cloisite-15A has a relatively higher impact on penetration and softening point of bitumen. By increasing Cloisite-15A content, penetration decreases from 63 to 45 and softening point increases from 54 to 61.
Softening point is the temperature at which a steel ball falls a known distance through the bitumen when the test assembly is heated at a known rate.
