WebGrades of straight-run bitumen are designated by two penetration values, for example, 40/50, 60/80, 80/100 etc.; the penetration of an actual sample of the bitumen in any grade should fall between the lower and upper value given. 10.1.1.3 Apparatus a) The test apparatus consists of a right frame which holds the needle spindle in a WebThe penetration is a key factor influencing bitumen quality and is disproportional to the value of softening point as can be seen in Figure 5. Figure 5 shows that by increasing the amount of the coal tar pitch, the penetration decreases while the softening point increases and that these two parameters are inversely related.
