1. Marshall Test

• Purpose: To determine the feasibility of asphalt-concrete aggregates in road design construction.
• Results: Marshall stability and flow, indicating the maximum load for asphalt concrete.
• Significance: Serves as a reference for testing asphalt mixtures using Marshall tools.
• Criteria: Aims to meet conditions set in planning criteria (SNI 06 2484, 1991).

2. Maximum Specific Gravity of the Mixture

• Definition: Ratio of the weight of the asphalt mixture in air cavity to its volume when air cavity is zero.
• Purpose: To calculate the void content of each asphalt content.
• Importance: Obtaining maximum specific gravity value of uncompacted asphalt mixture (SNI 03 6893, 2002).

3. Extraction of Asphalt Content in the Mixture

• Process: Separating materials using a solvent to dissolve one component.
• Common Solvents: Spiritus, gasoline, technical trichlorethylene.
• Purpose: To determine asphalt content in the asphalt mixture using centrifugal extractor or Soxhlet device.
• Reference Standard: SNI 03 6894, 2002.

4. Beklement Beam Test

• Definition: Tool for measuring deflection and inflection points in pavement.
• Purpose: To assess the back deflection of pavement structure under standard tire pressure and load.
• Outcome: Helps in calculating thickness of flexible pavement layers.
• Reference Standard: SNI 03 2416, 1991.

5. Asphalt Core Drill Test

• Purpose: To ensure pavement specifications match contractual agreements and to assess pavement thickness and density.
• Method: Conducted using a core drill machine to extract pavement samples from the field.
• Importance: Determines thickness and characteristics of the pavement mixture at predetermined STA points.
• Reference Standard: SNI 03 6890, 2002.
