Frequently Asked Questions

Gilsonite oil-based sealer is a petroleum-based product that penetrates into asphalt rather than sitting on the surface like water-based alternatives. It bonds at the molecular level and extends pavement life significantly longer. Most contractors in East Texas use only water-based products, but the penetrating action of gilsonite provides superior protection against UV damage and moisture intrusion.

Clay-heavy soils in East Texas expand when wet and contract during dry periods, creating movement under asphalt surfaces. Without proper road base and compaction, this shifting causes cracking and premature failure. A stable crushed stone base layer isolates the asphalt from soil movement and prevents settling that leads to low spots and water pooling.

Isolated potholes under 2-3 feet wide can be patched if surrounding asphalt remains structurally sound. When multiple potholes cluster together, cracking extends beyond the damaged area, or the base has failed, full section replacement prevents repeated repairs. Saw-cut patches last longer than simple fill because they create clean edges that bond properly.

Water seeps into small cracks, then expands when temperatures drop overnight during winter months. This expansion forces cracks wider, allowing more water penetration in the next rain cycle. East Texas experiences frequent freeze-thaw patterns from November through March, accelerating surface deterioration without preventive sealcoating to block moisture entry.

Base prep involves excavating existing material, grading for drainage, laying crushed stone or aggregate, then compacting in lifts to achieve stable density. Proper compaction prevents the base from shifting under traffic weight or settling during heavy rains. Skipping compaction steps or using insufficient base thickness causes premature asphalt failure regardless of surface quality.

Recycled asphalt millings compact and stabilize over time, creating a durable surface for residential driveways and low-traffic areas at lower cost than full asphalt. They work well in East Texas because the material contains residual binding agents that reactivate under heat and compaction. Millings aren't suitable for high-traffic commercial lots or areas requiring smooth finished surfaces.

Asphalt in East Texas needs sealcoating every 2-3 years due to intense UV exposure and high humidity that break down surface binders. Traffic volume, sun exposure, and whether gilsonite or water-based sealer was used all affect timing. Waiting longer than three years allows oxidation to penetrate too deep for sealcoat to restore properly.

Heavy East Texas rainfall saturates compromised asphalt, weakening the bond between surface and base layers. Traffic then displaces the saturated material, creating depressions that hold more water and accelerate breakdown. Potholes expand rapidly once they start because each vehicle passage ejects more loose asphalt from the edges.

Chip seal applies hot asphalt emulsion to existing pavement, then spreads and compacts stone chips into the surface to create a textured wearing layer. It preserves roads economically without the cost of full overlay. Regular paving lays thick asphalt over prepared base for new construction or complete replacement, providing a smooth finished surface suitable for all traffic types.

Traffic wear, UV exposure, and water pooling all degrade paint at different rates across a parking lot. High-traffic drive lanes and entrance areas fade within 12-18 months, while protected spaces last longer. East Texas sun intensity accelerates paint oxidation, and standing water from poor drainage lifts paint from the asphalt surface during freeze-thaw cycles.

Base depth requirements, site access, drainage grading, and total square footage all impact pricing. Properties with poor existing base or heavy clay soil need deeper excavation and more aggregate, increasing material and labor costs. Commercial projects requiring thicker asphalt for heavy truck traffic cost more per square foot than residential driveways designed for passenger vehicles.

DIY cold-patch products from hardware stores provide temporary fixes but don't compact properly or bond to existing asphalt edges. Professional repairs saw-cut clean edges, compact hot asphalt in lifts, and achieve proper density that prevents water intrusion. Temporary patches typically fail within one season, requiring re-repair at higher total cost than doing it correctly initially.
