Surcharge Weight 4.5kg Annular - SL104

Product code: SL104

Category: Soil and Geotechnical

Ring-shaped steel disk used in lab and field CBR testing. The 4.5kg annular surcharge weight is a ring-shaped steel disk used in California Bearing Ratio (CBR) testing. It is designed to apply a controlled, uniform surcharge load around the perimeter of a soil specimen, simulating the pressure exerted by overlying pavement layers or structural loads. It is used in both laboratory and field (in-situ) geotechnical testing to assess subgrade strength and performance. Key Features Precision-machined annular (ring-shaped) design Provides uniform load distribution during CBR testing Manufactured from durable steel for long service life Suitable for laboratory and field use Corrosion-resistant finish for improved durability Standardised dimensions for compatibility with CBR mould systems Technical Specifications Mass: 4.5 kg Type: Annular surcharge weight Material: Steel Inner Diameter: 54 mm Outer Diameter: 251.6 mm Thickness: 12.4 mm Available Options The following surcharge weights are available as part of the standard range: SL103 Surcharge Weight 2kg Annular SL104 Surcharge Weight 4.5kg Annular SL105 Surcharge Weight 9kg Annular SL106 Surcharge Weight 2kg Split SL107 Surcharge Weight 4.5kg Split SL108 Surcharge Weight 9kg Split SL115 Surcharge Weight 10lb Solid SL116 Surcharge Weight 5lb Split SL117 Annular Surcharge Weight 5lb Solid Applications California Bearing Ratio (CBR) testing Pavement and highway subgrade evaluation Soil strength classification Geotechnical laboratory testing Field (in-situ) soil compaction assessment Civil engineering construction quality control Delivery & Lead Time Standard items available from stock Typical delivery: 2–5 working days (UK, dependant on order quantity) Express shipping available on request (additional charges may apply) International delivery options available Compliance & Quality Manufactured to relevant geotechnical testing equipment standards Quality-controlled machining and weight calibration Each unit inspected for dimensional accuracy and finish quality Frequently Asked Questions Q: What is the purpose of an annular surcharge weight? A: It simulates overburden pressure on a soil sample during CBR testing to ensure realistic test conditions. Q: Why is the weight ring-shaped? A: The annular design allows load to be applied around the perimeter while keeping the centre clear for the penetration piston. Q: Can different weights be supplied? A: Yes, surcharge weights are commonly available in different masses depending on test requirements. Q: Is this compatible with all CBR moulds? A: It is designed to be compatible with standard CBR testing systems, but dimensions should always be checked. Request a Quote Ready to order or need more information?
