  • Q1. What tests are performed on aggregates and where do I take them?
     
    A1.    Three labs at the Materials and Tests Central Lab perform aggregate testing:
     
      • The Asphalt Lab test aggregates used in asphalt mixes,  
    Note: Except yearly quality samples, all aggregates may be taken to the Geomaterials Group Central Lab in Raleigh or one of the regional labs across the state. Aggregate samples need to have the appropriate sample tag attached to them.
     

    Q2. What is  Alkali-Silica Reaction (ASR) and what aggregate sources have been known to have issues with this in concrete mixes?

    A2. An explaination of what ASR is and the aggregate sources that have had issues with this is explained in this brief​.


    Q3. Who do I contact for annual Nuclear Gauge Calibrations?



    Q4. Who do I contact in my division with other questions regarding Conventional Density (Soil, ABC) or Density Gauge Questions? 

    ​A4. See the Materials and Tests GeoMaterials Section Employee Directory.​

     
    Q5. Where do I find current unit weights for quarry aggregates?
     


    Q6. Where do I find specific gravity, Absorption, Fineness Modulus, and Sulfate Soundness data for approved aggregate sources?
