LBS LABOUR INTENSIVE APPLICATION PROCEDURE
Adjust the size of the containers or buckets to hold the correct volumes of crusher sand, roadstone and bitumen emulsion for the final LBS Asphalt mix.
Load the measured crusher sand, roadstone and bags of LBS filler into wheel barrows for transportation to the road.
Place the bags of LBS filler the correct distance apart for the area to be covered by the seal and place the measured crusher sand and road stone alongside.
Mix the crusher sand, roadstone and LBS filler thoroughly.
Add the required quantity of bitumen emulsion to each mixed stockpile and mix thoroughly.
Place the thickness guides.
Apply water lightly to the base, sweeping off any freestanding water immediately (no prime is required).
Spread the prepared LBS Asphalt mix within the guides.
Level the LBS Asphalt mix to the required loose depth.
Lightly apply water and compact the area by roller with 2 to 3 passes using vibration (water the drums of the roller to assist with sticking of material).
Lightly water the compacted area again if required and continue rolling with 2 to 4 passes without vibration. Once the surface becomes saturated with a brown liquid sufficient water and compaction has been applied.
