CONCRETE ROADS FOR LOW TRAFFIC VOLUMES Brian Walker BCP Engineers
Advantages Of Concrete Roads • Ideal for emerging contractors • Low capital costs on plant • Can be laid on very steep grades • Little or no layerworks required • Low maintenance costs
Some Problems With Concrete Roads • Incorrect aspect ratios • Irregular shaped panels • Settlement of fills • Late saw cutting of joints • Plastic shrinkage cracks
Other Types Of Concrete Roads • Rollcrete • Interlocking concrete blocks
Summary • Lower maintenance costs • Helping emerging contractors • Low capital cost of plant • Ideal for steep grades • Can reduce the cost of drainage • Reduced requirement for scarce layerwork material
How Not To Build A Road • Inappropriate surfacing • Combined withno maintenance
