Description Mcleod or similar
Description Dirt jump style shovel slapping
Method Vibrating plate
Description There are various sizes and models. Small plates weigh between 50 to 70kg, medium plates up to 90kg and heavy plates even more.
Method Machine attachment
Description It is possible to get compactor attachments that can be fitted to construction equipment such as excavators which allow for machine compaction of berms and ttfs.
Description Rollers are used more commonly in import build urban bike park constructions where there are less obstructions to access and egress for the machine and generally flatter terrain and safer conditions.
Method Back blading with skid steer
Description Reverse the machine, dragging loose materials with you behind the blade. Monitor the amount of material being pulled behind the blade. As you reverse alter the angle of attack of the machine adding more weight to the back side of the blade, this will push the loose material into the ground and compact it.
Method Bucket smashing
Description Using the back of the excavator bucket to push or punch into the ground to compact soils. Used in hard to reach areas, backslope, backs of elevated berms. The technique is normally followed by a hand crew who will add additional compaction manually.
Method Layering compaction
Description Build up layers and compact these to create import build trails and features. 200mm layers. ‘Layer cake’
Method Direction of compaction
Description In general it is recommended to criss-cross the direction of compaction. The last compaction has to be done in the riding direction to have a smooth feeling (same for narrow trails). Only berms are compacted vertically (going up and down from inside to outside edge) with a last shovel slapping in travelling direction to smooth the inter-lines.
Method Soil stabilisers
Description Soil stabilisers are chemical, lime or clay-based additives to add into the soil.
