What truly makes a pavement last—and why shortcuts cost more in the long run.
At We Love Paving, durability isn’t luck—it’s engineering. Every parking lot, driveway, or road we build is a system of layers, compaction, slope, and drainage working together to withstand load, time, and climate.
This article breaks down the technical components that separate long-lasting pavement from premature failure, helping property owners and project managers understand the “why” behind every layer we install.
📏 1. Subgrade Evaluation and Stabilization
The subgrade is the native soil that supports the pavement system. If it’s weak, expansive, or poorly compacted, the surface above it will fail—no matter how thick the asphalt is.
Our Process:
-
Proctor compaction tests to determine ideal moisture and density
-
Subgrade compaction to 95%+ using heavy rollers
-
Soil stabilization (lime, cement, or geogrid fabric) for expansive or wet soils
-
Moisture conditioning if needed
💡 A poorly prepared subgrade is the most common cause of alligator cracking.
🧱 2. Aggregate Base Design
The aggregate base distributes the load from the pavement surface to the subgrade. Its depth and material type vary based on traffic volume, soil type, and project use.
WLP Specs:
-
Class II AB (crushed rock) installed at 4″–12″ depth
-
100% crushed, angular aggregate for better interlock
-
Layered compaction in 2″ lifts to 95%+ density
-
Slope engineered to 1–2% for surface water flow
We also design reinforced bases for dumpster pads, loading zones, and heavy-use areas using concrete collars or thicker base sections.
💧 3. Drainage and Surface Water Management
Water is the #1 threat to pavement. Without proper drainage, the base layer erodes, leading to subgrade saturation and failure.
WLP Drainage Solutions:
-
Crowned or cross-sloped surfaces (min 1%)
-
Curb and gutter tie-ins with drainage basins
-
Trench drains or French drains for high-volume areas
-
Edge support to prevent lateral water infiltration
🛠️ In mountain or coastal regions, we also recommend subdrain systems to control groundwater pressure.
🛣️ 4. Asphalt Layer Design
The surface asphalt must balance flexibility, load-bearing strength, and resistance to environmental factors like UV, oil, and thermal expansion.
Our Asphalt Specs:
-
Caltrans-approved hot mix asphalt (HMA)
-
Installed in 2–3 lifts depending on thickness
-
Compacted to 92–96% relative density
-
Mix design tailored to project type (e.g., commercial vs. residential)
We also use PG binders suited for local climate zones and aggregate gradation matched to expected traffic.
♿ 5. ADA Compliance Built Into Geometry
Proper slope, grade breaks, and transitions are essential for both safety and ADA compliance.
WLP ADA Engineering Includes:
-
Max 2% cross slope on accessible routes
-
Proper placement of truncated domes and curb ramps
-
ADA stall layout according to Title 24 and federal specs
-
Formwork, elevation checks, and signage during final walkthrough
We design ADA compliance into the plan set—not after the pour.
🔁 6. Post-Construction Maintenance Strategy
Even well-built pavement needs a lifecycle plan. Without sealcoating, crack repair, and re-striping, environmental exposure will degrade your surface.
WLP Maintenance Plans:
-
Sealcoat every 2–3 years
-
Crack sealing annually (or as needed)
-
Surface inspections at 6–12 month intervals
-
Refresh ADA markings and signage
🧠 Final Word: Durable Pavement Is Engineered—Not Estimated
A pavement’s longevity is not about the thickness of asphalt alone. It’s about the entire system: soil, base, drainage, slope, materials, and long-term planning.
At We Love Paving, we bring engineering precision to every inch—so your pavement performs like it should.
