Understanding The Subbase
The Foundation Behind Every Durable Pavement
A subbase is the engineered layer between natural subgrade soil and the final pavement. It distributes loads, limits settlement, improves drainage, and creates a stable working platform so asphalt or concrete performs as designed. Distinct from the base course, a well-built subbase mitigates rutting, pumping, and premature cracking by spreading traffic forces across a broader area.
Eric Smith Asphalt Paving builds subbases to specification using clean, well-graded aggregates compacted in controlled lifts. Proper thickness, moisture conditioning, and density verification are essential. When installed correctly, the subbase safeguards pavement life, reduces maintenance costs, and delivers smooth, long-term performance for driveways, parking lots, and roadways.
From Evaluation To Final Proof-Roll
We begin with site evaluation and soil characterization (visual classification, proof-rolling, and, when needed, laboratory CBR/Proctor). The subgrade is shaped to plan elevations, soft areas are undercut or stabilized, and separation or reinforcement geosynthetics are placed when warranted. Grades and crowns are set for positive drainage and to match adjoining structures.
Next, we install the specified aggregate—such as graded aggregate base or crushed stone—in uniform lifts. Each lift is moisture-conditioned and compacted with calibrated equipment to target density. We validate compaction and surface tolerances, fine-grade to tight elevations, proof-roll to confirm stiffness, and prepare the platform for the base course and final paving.
Engineered Aggregates, Correct Thickness, Verified Results
We select durable, angular aggregates with sound gradation for interlock and stability (e.g., crusher run or graded aggregate base). Material quality may be validated against project specs for abrasion resistance, fines content, plasticity, and cleanliness. Where appropriate, geotextile separators and geogrids control contamination and reinforce weak subgrades.
Subbase thickness is designed around anticipated loading and soil support—light-duty areas may require 6–8 inches, while heavy truck lanes and dumpster pads often need 10–14 inches or more. Drainage is addressed through cross-slope, edge outlets, and, when needed, underdrains to prevent moisture-related weakening and freeze-thaw damage.
Our quality program includes lab Proctor tests to establish optimum moisture, in-place density testing to confirm 95–98% compaction (per spec), and proof-rolling or lightweight deflectometer checks for uniform stiffness. We document results, correct variances promptly, and deliver a stable, smooth platform ready for long-lasting pavement.
