摘要:
FIELD: construction.SUBSTANCE: invention relates to the testing of road building materials. Method includes making samples, weighing them in air at a temperature of 20±2 °C, hold in water at 20±2 °C for 30 minutes, subsequent weighing of the samples in water at a temperature of 20±2 °C, removing excess moisture from the surface of the samples, then weighing them in air at a temperature of 20±2 °C, vacuuming in a vacuum chamber partially filled with water at a temperature of 20±2 °C at a residual pressure of 2,000 Pa (15 mm Hg), bringing the pressure to atmospheric, holding in water at a temperature of 20±2 °C, for 30 minutes at atmospheric pressure to saturate the pores released from the air with water, re-weigh in water, remove excess moisture from the surface of the samples and weigh them in air, and then calculate the water saturation. Vacuuming the samples placed on the stand inside the vacuum chamber above the surface of the water is carried out simultaneously with the evacuation of wat
