The Applied Technical Services Family of Companies (ATS FoC) provides ASTM C136 testing services. ASTM C136 is a widely recognized method to determine the particle size distribution, or gradation, of fine and coarse aggregates. Accurate aggregate gradation is essential for producing durable, high-performing concrete, asphalt, and other construction materials. ATS FoC helps contractors, producers, engineers, and project owners verify aggregate quality, meet project specifications, and maintain compliance with industry standards.
Can ASTM C136 Identify Problems with Aggregate Gradation?
ASTM C136 is the standard method for sieve analysis of fine and coarse aggregates. It measures particle-size distribution using a series of sieves. The test reports the percentage of material retained on each sieve and, combined with ASTM C117 wash analysis, shows the percentage passing the No. 200 sieve. ASTM C136 identifies gradation issues by highlighting distribution gaps, excessive fines, or surplus coarse particles, which may impact the following:
- Compaction
- Concrete strength
- Workability
Our ASTM C117 Testing Services
Our ASTM C136 aggregate testing services provide accurate and reliable sieve analysis to determine the particle size distribution of fine and coarse aggregates used in construction. Experienced technicians use advanced laboratory equipment and standardized procedures to evaluate aggregate gradation. This ensures compliance with project specifications, industry standards, and quality control requirements. The test measures the percentage of material retained on a series of sieves, providing detailed gradation data to support the following:
- Aggregate source evaluation
- Asphalt production
- Concrete mix design
- Road construction
Our ISO 17025-accreditted laboratory handles a wide range of aggregate types and sizes, providing precise results that help optimize material performance, consistency, and durability. Through rigorous quality assurance and efficient turnaround times, we assist contractors, producers, engineers, and project owners in verifying aggregate suitability and maintaining compliance with standards. Our ASTM C136 testing services deliver dependable data to support successful construction and infrastructure projects.
What Materials Can Be Tested Under ASTM C136?
We test a wide range of construction aggregates for concrete, asphalt, masonry, and general construction. Our services cover natural and manufactured materials, including specialty requests for recycled content. Typical materials include:
