Marshall Mix Design - Pavement Interactive

During the loading, an attached dial gauge measures the specimen's plastic flow as a result of the loading (Figure 2). The flow value is recorded in 0.25 mm (0.01 inch) increments at the same time the maximum load is recorded. Figure 2. Marshall stability testing apparatus. Typical Marshall design stability and flow criteria are shown in Table 1.

• DO guard against mixing different classes, types, and grades of emulsified asphalt in storage tanks, transports, and distributors. For example, if cationic and anionic emulsified asphalts are mixed, the blend will break and separate into water and coagulated asphalt that will be difficult to remove. Because it is hard to determine

GCA-05-N045 Low Temperature Asphalt - EAPA

With this method, the asphalt temperature is lowered by approximately 30°C without changing the viscosity of the bitumen. The zeolite in a dosage of approx. 3% m/m. related to the total mix can be applied up to a mixing temperature of up to 190°C. Therefore, it is not possible to apply zeolites for temperature reduction with mastic asphalt.
