Pengujian Penetrasi Aspal

Summary

This video demonstrates the process of conducting an asphalt penetration test. It begins by preparing the necessary tools and heating the asphalt to around 140°C. The asphalt is then poured into cups, cooled in a water bath at 60°C, and left for 30 minutes. Afterward, the asphalt is tested using a penetration testing device, ensuring the needle touches the surface at a specified distance. The final reading is compared with standard penetration classifications according to Indonesian regulations. The test ensures the asphalt's quality for specific uses.

Takeaways

• 😀 The script covers the procedure for conducting a penetration test on asphalt.
• 😀 Tools and materials required include a pot, a thermometer, a water bath, and a test container.
• 😀 The first step is to heat the asphalt to about 140°C using a stove and thermometer.
• 😀 Once the asphalt reaches the correct temperature, it should be poured into a container, covering it with tissue.
• 😀 The temperature of the container should be checked by holding its sides to ensure accuracy.
• 😀 Next, a water bath should be prepared, with the water heated to around 60°C.
• 😀 The cooled asphalt should then be submerged into the water bath, and the container should be closed.
• 😀 After 30 minutes, the asphalt is removed from the water bath and placed on a penetration test apparatus.
• 😀 The penetration test apparatus should be calibrated so that the needle touches the asphalt surface at 1 cm from the container's edge.
• 😀 The penetration test is started, and the results are recorded, ensuring they fit within the classification criteria based on Indonesian standards.
• 😀 The final penetration value is categorized into one of the two classification groups according to the Indonesian standard RSNI 501:2003.

Q & A

What is the initial step in the penetration test for asphalt?

The first step is to prepare the tools and materials needed for the test.

At what temperature should the asphalt be heated for the test?

The asphalt should be heated to approximately 140°C using a thermometer.

What should be done once the asphalt reaches the target temperature?

Once the asphalt reaches 140°C, it should be removed from the heat and poured into a container, filling it with three or four portions as needed.

How should the asphalt be checked for temperature during the test?

The temperature should be checked by holding the container and feeling the sides for warmth.

What is the purpose of the water bath in the test process?

The water bath is used to cool the asphalt. The water should be heated to about 60°C.

How long should the asphalt be submerged in the water bath?

The asphalt should be submerged in the water bath for about 30 minutes.

What should be done after the 30 minutes of cooling?

After 30 minutes, the asphalt should be removed from the water bath and placed into a container of water, then positioned on the penetration test device.

What is the next step once the asphalt is placed on the penetration test device?

The needle should be adjusted to touch the surface of the asphalt, set 1 cm away from the edge of the container.

What is the function of the 'on' and 'start' buttons on the penetration test device?

The 'on' and 'start' buttons activate the device to begin the penetration test, allowing the needle to penetrate the asphalt.

What should be done after starting the penetration test?

The readings on the penetration test device should be monitored, and the value recorded to determine the penetration classification.

How is the penetration classification determined?

The penetration value is compared to the classification standards set by RSNI No. 501 2003 to ensure it falls within the appropriate category for asphalt in Indonesia.
