We work with developers, builders, HOAs and engineers, and we sequence paving around utilities, curbs and construction traffic so the street is delivered on schedule.
Subdivision Road Paving Sections: Base, Surface and Traffic Design
Road sections are designed by an engineer from soils, expected traffic and local standards. Residential streets commonly combine a few inches of asphalt over a thick crushed surfacing base, with heavier sections at intersections, cul-de-sacs and collector roads. We build to the plans and flag conditions in the field that may warrant engineering review, such as soft subgrade or unexpected groundwater.
Subdivision Road Paving Subgrade: Proof-Rolling, Stabilization and Geotextile
Subgrade is proof-rolled to find soft areas, which are removed and replaced or stabilized. In wet or silty soils, geotextile fabric and thicker crushed rock sections can protect against pumping and frost-related failure.
Subdivision Road Paving Equipment: Graders, Pavers and Compaction Fleet
Motor graders fine-grade the base, pavers place the asphalt at a controlled thickness, and a roller train compacts the mat to density. Pavement joints, utility covers and curb lines receive extra attention because they are common entry points for water.
Subdivision Road Paving Drainage: Crowns, Gutters and Stormwater Tie-Ins
Road crown, gutter slope, inlets and swales move stormwater off the street and into approved drainage facilities. We construct to your plans and protect inlets during paving to meet stormwater requirements.
Subdivision Road Paving Sequencing: Binder Course, Final Lift and Warranty Inspections
Many developers place a base lift early to support construction traffic, then wait to place the final surface lift after homes are built. This reduces damage and gives a smoother finished street. We plan lifts, patch construction damage before the final lift and coordinate inspections. For maintenance after turnover, see asphalt resurfacing and asphalt sealcoating.
Subdivision Road Paving Process: Utilities to Final Lift
- Pre-construction coordinationWe review plans, utilities, inspection requirements and schedule.
- Subgrade preparationSubgrade is proof-rolled and corrected.
- Crushed surfacing placementCrushed rock is placed and compacted in lifts to grade.
- Fine gradingGraders and string-line or machine control establish final grade.
- Base lift of asphaltA first asphalt lift is placed and compacted.
- Final liftAfter construction, damage is repaired and the surface lift is placed.
- Striping and turnoverMarkings are applied and the street is prepared for inspection.
