Choosing a pavement for a busy yard or access route starts with understanding how the surface will be used. Roller compacted concrete (RCC) and asphalt are different pavement systems, and neither is automatically the right choice for every site. Loads, turning movements, subgrade conditions, drainage, construction access and long-term maintenance all belong in the comparison.
How the pavement systems differ
RCC is a low-slump concrete mixture placed with paving equipment and compacted with vibratory rollers. Asphalt is a bituminous pavement placed and compacted as a hot mix. Their materials, construction methods, joint details and maintenance needs differ, so a cost comparison should use comparable designs and project assumptions.
Start with site use and loading
List the vehicles and equipment that will use the pavement, including axle loads, frequency, turning paths, braking locations and stationary loads. A route used by occasional passenger vehicles presents a different design problem from a loading area with repeated heavy truck movements. Share traffic data with the pavement designer rather than relying only on the site's total square footage.
Compare lifecycle requirements
Ask for the initial construction scope, expected maintenance activities, access restrictions during repairs and the planning period used in any lifecycle estimate. Maintenance costs depend on design, materials, drainage, climate, construction quality and actual use. Request assumptions in writing and compare options on the same basis.
Account for construction and drainage
Review the condition of the subgrade, available work space, tie-ins to existing pavement, utility locations and how runoff will be managed. A strong pavement surface cannot compensate for unresolved drainage or foundation problems. The site plan should also show how construction can proceed while protecting nearby operations.
Questions to take into a planning meeting
- What vehicle and equipment loads should the design accommodate?
- Which areas have repeated turning, standing loads or concentrated traffic?
- What subgrade and drainage work is included in the scope?
- How will construction affect access and daily operations?
- What maintenance assumptions support the lifecycle comparison?
