PUMA

A new type of laboratory testing equipment designed to fill the gap between expensive and complex laboratory tools (such as triaxial cells) and more empirical methods (such as the California Bearing Ratio test).
It is designed to generate realistic values of modulus for use in pavement design.

PUMA can be used to test unbonded, hydraulically bonded and asphalt materials. It has been designed as an affordable, simple and practical tool, capable of generating scientifically meaningful data (modulus and resistance to permanent deformation), for use in pavement design.

It can be used to test samples made of granular material, soil or lightly stabilized material, etc., with a maximum particle size of 31.5 mm.

Key Features Puma

• Designed for use within a UTM cargo frame
• Compatible with existing loading systems currently used for asphalt testing
• Compaction can be performed using existing vibrating hammer equipment
• Flexibility to change stress ratios (vertically and horizontally) and number of load cycles if desired
• Possibility to perform the test directly under DPT equipment to simulate as close as possible to the probable "on-site" DPT value.
• The equipment can be used on all unbound materials with particle size up to 31.5 mm
• Suitable for testing on hydraulically bonded materials
