150mm Mold Assembly for AFGB1

This 150mm mold assembly is designed for preparing asphalt specimens in a compatible GB1 Brovold-style gyratory compactor. It provides the cylindrical forming surface needed to consolidate loose asphalt mixtures under controlled gyratory compaction. A dedicated replacement or additional mold can reduce downtime between batches and help laboratories manage routine wear. The HMA listing states that a certificate is included, making it useful for documented mold management.

Key Features

• The manufacturer identifies 150mm GB1 molds as meeting the dimensional requirements of AASHTO T 312 and ASTM D6925.
• A purpose-built mold assembly supports proper fit and specimen formation in the compatible gyratory compactor.
• Keeping a second mold on hand can reduce waiting time between specimen batches and improve laboratory throughput.
• A dedicated mold simplifies scheduled inspections and replacement when bore wear affects testing.
• A supplied certificate provides useful documentation for laboratory quality records, subject to verifying the certificate scope.
• The design supports standard 150mm asphalt mix-design specimens used in routine gyratory compaction.

Included Items

One 150mm mold assembly and certificate, as listed by HMA; mold plates and extractor accessories are not confirmed.

Lab Manager's Tip

Verify compatibility with the GB1 machine and inspect the mold bore, finish and plate condition before each test series. For AASHTO T 312 and ASTM D6925, follow the current mold dimensional tolerances and required specimen preparation procedure.

Typical Applications

Superpave gyratory compaction, asphalt mix design, 150mm specimen molding and gyratory compactor maintenance.
