Asphalt Mixers NL 2034 X / 003N

(Bitumen & Asphalt Testing Equipments)

Description

Standard: ASTM D1559, EN 1269/35, BS 598-107

Asphalt Mixer

The Asphalt Mixer is used for bituminous homogenous mixing by blending bitumen with aggregates to create a uniform mixture for asphalt pavement, highways, parking lots, and other surfaces requiring durable and weather-resistant pavement.

The mixer has been designed for bituminous homogenous mixing and consists essentially of a horizontal tilting thermostatic drum. The tilting drum is at 130° angles. The mixing chamber is heated by the dielectric chamber with diathermic thermostatic control. The unit comes with a PID temperature control unit with a digital display. This large capacity heavy-duty mixer is designed to mix bituminous samples for tensile splitting tests, compaction tests, marshall and other tests where uniformity is required. The mixer mixed homogeneous, uniform efficient fast mixture action. They are of easy and practical utilization suite for laboratory purposes. This mixer features 20 litres capacity. The bituminous mixture can be easily discharged by the total turnover of the mixing chamber.

Test Procedure

Test Procedure of Asphalt Mixer

  • Aggregate and Asphalt Cement Preparation: Prepare the aggregates, sand, fillers, and asphalt cement according to the mix design specifications. Ensure that the materials are properly graded and proportioned for the desired asphalt mix.
  • Heating the Mixer: Heat the mixing chamber to the specified temperature using the heating system. Maintain the temperature within the desired range throughout the mixing process.
  • Loading: Load the preheated aggregates, sand, fillers, and asphalt cement into the mixer in the prescribed proportions. Ensure that the materials are added gradually and evenly to promote thorough mixing.
  • Mixing: Start the mixing process and allow the materials to blend inside the mixer. Monitor the mixing time to ensure that the mix reaches the desired level of homogeneity.
  • Sampling: Take samples of the asphalt mix at regular intervals during the mixing process. These samples will be used for testing the properties of the mix, such as gradation, density, and binder content.
  • Discharge: Once the mixing is complete and the desired homogeneity is achieved, discharge the asphalt mix from the mixer. Ensure that the discharge mechanism is functioning properly and that the mix is discharged completely.
  • Data Evaluation: Evaluate the test results to ensure that the asphalt mix meets the specified quality requirements. Make any necessary adjustments to the mix design or mixing process based on the test results.
