road work is divided :
- Employment Mapping ( Measurement of the road )
- Clearing and grubbing work ( cleaning the road of trees and topsoil )
- Stripping Employment ( Establishment of the road )
- Employment Sub Grade ( soil compaction )
- Employment Sub Base Coarse ( Foundations Down )
- Employment Base Coarse ( Foundations Upper ) . Add Prime Coad ( Base Layer Binding between coarse and ATB )
- Employment Wearing Coarse ( top layer ) = ATB . Add Take Coad ( adhesive layer between ATB and Hotmix )
- Employment Coarse Surface ( Surface Layer ) = hotmix
- Employment Marka Street
- Installation of Street Signs
- cleaning and leveling of land
- Before the highway was built , the land formerly cleared of rubbish and subsequently flattened trees .
- to clear land and dig the ground
Once the land was cleared and then do land leveling work using the bulldozer tool .
- excavator
To move soil excavation then used dump truck
- bulldozer
Work subbase material
Work subbase material in the form of stone using dump trucks transport then leveled and compacted by using a tandem roller
- tandem roller ~ Work in alignment with tandem rollers do again when penghamparan foundation layer above , and lapir surface. when the job is done penghamparan foundation materials urugan elevation measurements with theodolite tool
Work the soil material selection , base B , a base , the shoulder using a motor grader . While using a vibrator roller compacting . then to clean the dust on the surface of the base of a used air compressor , new prime coat overlaid
Road Works with Asphalt Coating
After the subbase layer is completed, the next process is asphalt work that previously has been preheated to melt
To work on asphalt used asphalt finisher tool .
- Asphalt Finisher ~ Having successfully worked with a layer of asphalt road elevation has been measured using a theodolite according to plan the next step is to meet with a bulldozer compaction density and elevation are planned .
The next job is finishing compaction and leveling of the highway with a roller tool peneumatic Roller Peneumatic
Highway construction has been finished with the following
