Tiger: This ancient Chinese animal symbol is an emblem of dignity, ferocity, sternness, courage, and by itself is Yin energy. Also a symbol of protection, the image of a tiger is often seen on clothing or in the home to ward off harm any semblance of harm and assure safekeeping.
Sensitivity to the length of the asphalt segment is given in Figures 19 and 20. The minimum temperatures at the asphalt surface change by 1.5C when the length of the asphalt segment is assumed to be 1 m long. The maximum temperature changes significantly by about 7.2C when an infinitely long segment is considered.
A.3 R&BT TEMPERATURE. The softening point of asphalt binder as measured by AASHTO T53-08 is also known as R&BT. According to literature on the topic, this temperature, measured in Fahrenheit, corresponds to the temperature at which asphalt binder has a viscosity of 13,000 P (1,300 Pas).n this test, a 3.5-oz (100-g) needle is used to penetrate an asphalt sample for 5 s. The amount of penetration, measured in tenths of a millimeter, is the penetration number for the asphalt binder at the particular test temperature.
