Aggregate Base Course (1″, Txdot)

Aggregate Base Course, TxDOT Specification, 1” Size Range

Aggregate Base Course meeting TxDOT specifications in a 1" size range is a high-quality, crushed stone material engineered for use as a stable foundation layer in roadways, parking lots, and other heavy-duty surfaces. Produced by crushing and screening durable rock, this base course is designed to meet the rigorous standards set by the Texas Department of Transportation, ensuring consistent gradation, strength, and compaction properties.




The 1" size range offers an optimal balance between load-bearing capacity and compaction, making it ideal for supporting asphalt or concrete pavements. Its angular shape interlocks well, reducing movement and providing excellent stability, while the TxDOT attribute guarantees reliable performance and compliance for public infrastructure projects. Common applications include road base, driveways, commercial site pads, and underlayment for sidewalks and patios. The main advantage of this material is its superior compaction and load distribution, though its coarse texture may not be suitable for decorative or surface applications.
