Product details
Asphalt specific gravity test balance
- The product is suitable for road paving, geological exploration, and lane research laboratories.
- Principle: According to GB/T2413、1966、2834、ASTMC20/C134/C373/C329、EN-725-10、AASHTOT166、ASTMD6572、T0705 standard. Suitable for boiling, vacuum saturation method, wax sealing method, and surface drying method. Can quickly and accurately read the measured values.
When conducting asphalt density tests, different methods should be used based on the characteristics of the mixture itself:
Dry method: suitable for type 1 or type 2 asphalt specimens with rough but dense surfaces
Water weighing method: suitable for dense type I asphalt specimens
Wax sealing method: suitable for type 1 or type 2 asphalt specimens with a water absorption rate greater than 2%
-
Volume method: suitable for asphalt crushed stone mixtures with large voids and open graded asphalt specimens with large voids and permeability
（GP型） Model of GP (MH type) Model of MH
Mode 1: Directly read the volumetric density of compacted asphalt mixture, Mode 1: Directly read the volumetric density and apparent voids of compacted asphalt mixture
Consider porosity, wet density, and volume. Rate, wet density, volume.
Mode 2: The wax sealing method can directly read the bulk density for water absorption rates>2%. Mode 2: The wax sealing method can directly read the bulk density for water absorption rates>2%
