ASTM RR:D04-1027 PDF Download

The ASTM RR:D04-1027 standard is a standard developed by ASTM International Committee D04 on Road and Paving Materials. This standard provides guidelines for testing preformed expansion joint fillers used in concrete construction.

The standard specifies two types of preformed expansion joint fillers: nonextruding and resilient. Nonextruding fillers are designed to prevent the extrusion of the filling material under compression, while resilient fillers are able to accommodate movement and recover to their original shape after deformation.

The standard outlines various test methods to evaluate the performance and quality of these fillers. These tests include measuring the dimensions, density, water absorption, compressibility, recovery after compression, and resistance to gas permeability. The standard also defines the procedures for sampling and conditioning the specimens before testing.
