ASTM C936/C936M is the ASTM standard that defines the Standard Specification for Solid Concrete Interlocking Paving Units. It provides a technical reference for evaluating paving units intended to interlock in installed systems, helping buyers, specifiers, and manufacturers align on product expectations. By focusing on solid concrete units, ASTM C936/C936M supports more consistent material selection, quality control, and procurement decisions for paving applications where dependable unit performance matters.

Purpose of ASTM C936/C936M

The purpose of this standard is to establish a clear specification for solid concrete interlocking paving units. It serves as a common technical basis for product compliance and comparison, helping reduce uncertainty when units are selected for paving projects. ASTM C936/C936M is typically used to support consistent manufacturing and purchasing decisions, and it may also guide acceptance checks where solid concrete interlocking units must meet defined specification requirements.

Common use cases of ASTM C936/C936M

This standard is commonly referenced when solid concrete interlocking paving units are specified, purchased, or reviewed for paving installations. It is useful in project specifications, product submittals, and quality assurance workflows where the paving units must meet an agreed ASTM standard. ASTM C936/C936M is also relevant for manufacturers and testing laboratories that need a reliable reference for product classification and conformance documentation.

Why ASTM C936/C936M matters

ASTM C936/C936M matters because it helps create consistency in the evaluation of solid concrete interlocking paving units. For procurement and compliance teams, the standard supports clearer product comparison and more defensible acceptance criteria. It may also reduce project risk by giving engineers, suppliers, and inspectors a shared technical language for specification review and quality control. In practice, that can improve coordination and help avoid ambiguity during purchasing and installation planning.
