Aggregate Testing Services in Midland, TX, for Base, Concrete, and Asphalt
Before aggregate goes into base, concrete, or asphalt, it has to meet spec. Magrym provides aggregate testing services in Midland, TX, for contractors and producers, from sieve analysis to soundness, with certified results that show how the material compares to the project specification.
The Material Under Everything You Build
Aggregate is in the base under your pavement, the concrete in your structure, and the asphalt on your road. Aggregate testing proves the rock and sand meet the gradation, cleanliness, and durability the specification demands before they go into the work. If the aggregate is out of spec, everything built with it inherits the problem.
The questions are always the same. Is the gradation right. Is there too much fine material. Will it hold up to weather and traffic. Magrym runs an AASHTO accredited lab in Midland that answers them with every aggregate quality test we run, delivering certified results that let a supplier qualify a source or a contractor accept a delivery without guessing.
We test aggregate for base, concrete, and asphalt against the project and agency specifications, and deliver certified reports formatted for your submittal. You talk directly to the lab, and we flag an out-of-spec result so it gets caught at the stockpile, not in the finished work.
Fine Aggregate Test and Coarse Aggregate Properties That Matter
We test the gradation, cleanliness, durability, and physical properties that determine whether an aggregate qualifies for base, concrete, or asphalt, running every fine aggregate test the specification calls for alongside the matching coarse aggregate work.
Sieve Analysis
We run the gradation through a full set of sieves to confirm the particle-size distribution meets the specification for the intended use.
- Coarse and fine gradation
- Percent passing each sieve
- Spec band comparison
Atterberg Limits
We determine the liquid limit, plastic limit, and plasticity index of the fines, the measure of how the fine material behaves with moisture.
- Liquid and plastic limits
- Plasticity index
- Sand equivalent
Specific Gravity and Absorption
We run a specific gravity test for fine aggregate to measure how the sand performs in the mix. We also run a specific gravity test for coarse aggregate, capturing water absorption and unit weight, the values mix designs depend on for accurate proportioning.
- Coarse and fine specific gravity
- Water absorption
- Unit weight and voids
Durability and Soundness
We test how the aggregate stands up to abrasion and weathering, running Los Angeles abrasion test services alongside soundness testing, so the material can survive the traffic and climate it will face in service.
- L.A. abrasion
- Soundness (sulfate)
- Durability index
Cleanliness and Deleterious Material
We check for the clay, silt, and deleterious particles that weaken concrete and base, including a full organic impurities test for fine aggregates, confirming the aggregate is clean enough for the spec.
- Material finer than No. 200
- Clay lumps and friable particles
- Organic impurities
Certified Reporting
Every result is delivered in a certified report formatted for your submittal or source qualification, with out-of-spec results flagged immediately.
- AASHTO accredited results
- Source qualification support
- Out-of-spec flagged immediately
Who Relies on Our Aggregate Testing
From the pit to the pour, aggregate has to be qualified before it goes into the work.
Aggregate Producers and Pits
Producers need to qualify a source and document that the material meets agency and project specs. We provide the certified testing that backs up the stockpile.
General Contractors
Contractors need to accept aggregate deliveries against the spec before they go into base, concrete, or asphalt. We test the material so the work is built on qualified rock.
Transportation and Roadway
Roadway base and surface aggregates carry strict gradation and durability criteria. Our AASHTO accredited lab provides results that meet the standards these projects require.
Concrete and Asphalt Producers
Mix designs depend on accurate aggregate properties, including the coarse aggregate tests for concrete that set gradation and specific gravity inputs. We provide the gradation, specific gravity, and cleanliness data that mix proportioning is built on.
A Local Lab That Keeps Your Material Moving
Aggregate results are only useful if they are correct and on time. Magrym provides certified aggregate testing services in Midland with the technicians and turnaround to qualify your material and keep your project moving.

From Sample to Certified Report
A clear path that qualifies your material against the spec.
Scope and Sample
We confirm the spec and intended use, and either receive your sample or collect a representative one from the stockpile or delivery. Fixed-fee proposal up front.
Lab Testing
We run the gradation, plasticity, specific gravity, durability, and cleanliness tests the specification requires, in our AASHTO accredited lab.
Spec Comparison
We compare every result against the project or agency specification and confirm whether the aggregate qualifies for its intended use.
Certified Report
You receive a certified report formatted for your submittal or source qualification. Any out-of-spec property is flagged so it gets handled before the material is used.
Frequently Asked Questions
Aggregate testing verifies that the rock and sand used in construction meet the gradation, cleanliness, and durability requirements of the specification. It includes sieve analysis, Atterberg limits, specific gravity, soundness, and cleanliness tests. The results qualify the aggregate for use in base, concrete, or asphalt and are documented in a certified report.
A sieve analysis, or gradation test, passes a sample of aggregate through a stack of sieves of decreasing opening size and measures the percent retained on each. The result is the particle-size distribution, which is compared to the specification band to confirm the material is the right blend of coarse and fine for its intended use.
Specific gravity and absorption are needed to design and proportion concrete and asphalt mixes accurately. Specific gravity converts between weight and volume of the aggregate, and absorption accounts for water the aggregate will take up. Without correct values, the mix proportions and water content can be off, which affects strength and durability.
Yes. Magrym operates an AASHTO accredited materials laboratory in Midland, TX. The accreditation means our procedures, equipment, and quality systems meet the national standards required for state, municipal, and federal submittals, so the certified results are accepted for source qualification and project acceptance.
Yes. We test aggregate sources for producers and contractors who need to document that a pit or stockpile meets agency and project specifications. The certified results support qualifying a source and accepting deliveries, so the material is proven before it goes into the work.
Yes. Magrym provides materials testing, land surveying, and civil engineering under one roof. The same lab can test the aggregate, concrete, and soil on a project, and the same firm can provide the survey and engineering, which keeps the data consistent and the coordination simple.
