CAP Covers Easily Surpass the American Traffic Standard

... With "Flying Colors" (Dr. Robert Jones, University of Texas, RGV)

The American Association of State Highway and Transportation Officials (AASHTO) designates the Standard Specification for Drainage, Sewer, Utility, and Related Castings - M 306-10.  Section 6 of this standard details the Proof-Load Testing.

Almost zero permanent deformation!

"H-20" and "H-25" certification methods use 40,000 lb and 50,000 lb loads, respectively, on a 9x9 platen for 1 minute.  After releasing, permanent deformation cannot exceed 0.125 inches.  CAP's cover with a 32-inch span deformed less than 0.02 inches after a 50,000 lb load (H-25). 

CAP Has Internal Proof Load Testing Capabilities (photo)

While our certification testing is with a third-party laboratory, CAP has the capability to test in-house for development and quality inspections.

Snowplow Resistance

Minor wear to surface, but overall integrity maintained.

Salt and Snow - No Problem

Material did not corrode or degrade.

CAP ONE - 30 Cover Resists More than 115,000 lbs!

CAP Cover shows remarkable retention of strength

“Cover shows... remarkable retention of strength”

Because of the dramatic H-25 result, CAP decided to discover where the product would reach failure. Our CAP ONE 30, with a 32 inch span, reached 116,000 lbs of force on a 9-inch x 9-inch platen.  This is like stacking more than two tractor trailers on top of each other and standing the bottom truck on one tire!
