A series of viscosity measurements were conducted on two specimens, one for 90% BSS modified binders, other is for the Neat asphalt, both of them have the same process but different temperature but same rpm. For BSS viscosity measurement, shearing was applied using spindle V-73 at a speed of 1, 2, 3, and 4 rpm. Viscosity measurement was conducted using Brookfield Viscometer (ASTM D4402). In this test, the viscosity, torque, and shear stress are determined while applying a rotational shear on the specimens. To prepare specimens, 10.5 grams of 90 bitumen scrap shingle sample was poured into aluminum chamber. The thermoset was preheated at its designated temperature for 45 minutes. Samples and the spindle were preheated in an oven for 45 minutes at 180 C before being placed into the aluminum chamber in thermoset. After loading the sample, an additional 30 minutes waiting time was used to ensure thermal equilibrium. The replicate was used for each test temperature and the average of the three values was recorded as the viscosity at the specified temperature and speed. For the neat binder the thermoset was preheated in an …show more content…
The magnitude of the VTS is directly proportional to the temperature susceptibility of the binder (Rasmussen et al. 2002). The VTS values were reported to range from −3.35 to −3.84 (U.S. DOT 2011), which is almost consistent with values of −3.36 to −3.98 reported by Rasmussen et al. and Puzinauskas (Rasmussen et al. 2002 and Puzinauskas 1967).

Shear susceptibility
Shear susceptibility is the rate of change in viscosity with the shear rate (Roberts et al. 1996). The shear susceptibility is determined by calculating the slope of the line formed by a log of shear rate versus the log viscosity graph by using the following equation (Raouf and William 2010).

• ## Gravimetric Analysis Of Sodium Silicate Solutions

The results were expressed in min, and the time was counted from the mixture of MK+WTS with the alkaline solution. Temperature kinetics curves of the geopolymer binders were obtained with a semi-adiabatic calorimeter, which was isolated from the external environment. The test was made to observe the temperature rise with time and to verify the exothermic geopolymerization reactions in the first hours after mixing. Thermocouples (K-type) registered the temperature. Data were recorded each 10 seconds for a period of 25 h by a datalogger Testo 177-T4.…

Finally, the electrical energy converted to heat was calculated. The voltage, current and time was considered. Therefore; Volt x ampere x time = Q Q (Copper) = 10.020 x 3.261 x (60 x 8) = 15684.12J Q (Aluminum) = 9.997x 3.254 x (60 x 8) = 15614.51J Having obtained this, the specific heat of water was calculated using the formula, Q/m∆T.The SHC for the copper at 8 minutes was calculated to 775J/Kg℃.

• ## 7.59 From The Stress Strain Data For Poly (Methyl Methacphiet?

For copper, the critical resolved shear stress is 2.10 MPa (305 psi) at a dislocation density of 105 mm-2. If it is known that the value of A for copper is 6.35 10-3 MPa-mm (0.92 psi-mm), compute the crss at a dislocation density of 107 mm-2. Solution We are asked in this problem to compute the critical resolved shear stress at a dislocation density of 107 mm-2. It is first necessary to compute the value of the constant 0 (in the equation provided in the problem statement) from the one set of data. Rearranging this expression such that 0is the dependent variable, and incorporating appropriate values given in the problem statement Now, the critical resolved shear stress may be determined at a dislocation density of 107 mm-2…

• ## Analysis Of Enthalpy

The specific heat, s, is known for most substances. Another equation needed is for calculating heat for objects with a fixed mass, like the calorimeter: q=C∆T. When these two equations are plugged into the first one, and it is expanded out, the resulting equation looks like this: “C_cal (T_f-T_(i,cw) )=-(m_cw )(s_water )(T_f-T_(i,cw) )-(m_hw)(s_water)(T_f-T_(i,hw))” (French et al, 105). Note that all of the substances reach the same final temperature. Temperature was measured during the reaction, allowing the amount of heat absorbed by the solution and the calorimeter to be measured.…
