Equipment Specifications	Capacity	Model and Year of Manufacture	Manufacturer Company and Country	Test Standard	Device Status - Quantity
Extraction	1500gr	AS 100-2005	Azmoonsaz Mabna - Iran	ASTM D2172	Sound - 1

General Specifications:
This device is used for extracting bitumen from asphalt and determining the bitumen content. A sample of up to 1500 grams is placed in the bowl, and by adding solvent and rotating the bowl using a lever, the bitumen can be separated from the asphalt, leaving only the aggregate materials. The device includes an aluminum bowl and lid with a capacity of 1500 grams, mounted on an aluminum base. The suitable filter for this device has an outer diameter of 250 mm.

Softening Point Apparatus for Bitumen

Equipment Specifications	Capacity	Model and Year of Manufacture	Manufacturer Company and Country	Test Standard	Device Status - Quantity
Bitumen Softening Point Apparatus	-	BI 130 -2007	Azmoonsaz Mabna - Iran	ASTM D36	Sound - 1

General Specifications:
The softening point of bitumen, among other factors, depends on temperature variations—softening increases as temperature rises. This simple apparatus, designed to determine this property, includes:

• A temperature-adjustable heating unit
• An 800 ml Pyrex beaker with a magnetic stirrer
• Two brass rings (molds)
• Two guide supports
• One steel ball

This setup is typically used in the Ring and Ball method to determine the softening point of bitumen.

Gradation Shaker	8-12 inch diameter	So 410	Azmoonsaz Mabna- Iran	ASTM-D422	Sound - 1

General Specifications:
The device operates with both vertical and horizontal motion powered by a vibration motor, ensuring optimal sieving results for aggregates and sand.

To facilitate the sieving process, an electric-powered Sieve Shaker is used. It features:

• A frame designed to hold 8-inch or 12-inch sieves
• A horizontal clamping lever to secure the sieves
• A nearly circular base plate with concentric grooves sized for 8 and 12-inch sieves, ensuring centered placement within the frame

This configuration enhances efficiency and accuracy in particle size analysis.
