How Is Heavy-Duty Pavement Designed for Cargo Terminals?

The design loads come from the fleet: reach stackers and top handlers with their axle weights, the stacking heights that set corner-casting point loads, and the travel patterns that determine repetitions. The engineer runs these through pavement design methods to get the required section — slab thickness for concrete, layer depths for asphalt — and checks the corner-casting punching load explicitly, because it governs in the stacking blocks. Concrete versus asphalt is decided by load intensity, maintenance capability, and construction staging: concrete costs more upfront and lasts under the loads; asphalt is cheaper and easier to phase but needs more frequent renewal in heavy areas.

The geotechnical investigation sets the foundation design: soft or saturated soils get improvement — stabilization, overexcavation, or geosynthetics — so the pavement structure bears on something competent. Drainage is designed as part of the pavement, not after it: the surface sheds water to inlets, and the base drains so saturation never softens the support. In concrete, the joint layout is engineered for the panel sizes the loads allow, with dowels or aggregate interlock for load transfer and sealants that keep water out of the joints — unsealed joints pump, fault, and fail.

Terminal pavement lasts when the section matches the equipment and the foundation stays dry. The handlers will find every weakness. • Pavement section designed from the actual equipment fleet's axle and point loads • Corner-casting punching loads checked explicitly in the stacking blocks • Subgrade investigation with stabilization where soils are weak or wet • Drainage integrated into the pavement design, keeping the structure drained • Joint layout, load transfer, and sealing detailed for heavy channelized traffic
