AS PER ASTM D1559,ASTM D5581, AASHTO T245, EN 12697-12, EN 12697-34
Salient features
Temperature Conditioning: The water bath maintains a uniform temperature (typically 60 ± 1 °C or as specified) to condition the asphalt specimens before loading. This ensures the material exhibits properties similar to field conditions.
Uniform Heating: It prevents localized overheating or underheating, which can influence the stability and flow values.
Reproducibility: Accurate temperature control ensures consistent test results, critical for comparing asphalt performance across different mixes or batches.
Technical Specifications
- Double walled water bath
- Inner chamber is made of mirror polished stainless steel material S.S. ‑ 304 Grade, Fully Argon Welded
- Exterior body is fabricated from Mild steel material, which is powder coated in attractive shades.
- The gap between the inner chamber and exterior body is filled with glass wool insulation to prevent the thermal heat loss
- Temperature inside the bath is controlled by Microprocessor based Auto‑tune Digital temperature controller cum indicator.
- Temperate ranges from : 5 °C above ambient to 100 °C,
- Temperature accuracy will be of ± 0.5 °C
- The bath is also fitted with a constant speed stainless steel stirrer to maintain uniform temperature distribution within the bath chamber.
- The bath is so designed that it can accommodates at least 9 Nos. of 4" diameter marshal moulds and breaking head assembly on heavy platform.
