Option 1 :

Full depth asphaltpavement withunmodified penetration

70/100.Advantages :

- Cost

- Durability- Sources available

- Maintenance

- Long life span

Bridge

Location of bridge : chainage 1+850 to 1+870

Length = 20m

Beam bridge

Cost effective, easy to manufacture

Can resist bending and twisting


17/22

Drainage

Types of drainage design:

1. Traversable Ditch with Concrete Lining

2. Symmetrical or V-shaped Ditch

For superelavation at the horizontal alignment, openchannel ditch is used with the frame and vane cratesinlet.

Culvert is also installed to allows water flows

underneath the road, then divert them to low-lyingarea.

Traversable Ditch withConcrete Lining

Symmetrical or V-shapedDitch


19/22

Drainage Maintenance

Cutlassing or cleaning off the ditch regularly to avoidthem from silting up and sending water back to the road.

Provide vegetation to reduce soil erosion at the side

slope of the V-shaped ditch.


20/22

Conclusion

Route length is 2.615km with one bridge. Road standard of R5 with design speed of

85km/hour.

Design consideration is following the standard Embankment volume > Excavation volume

Therefore, volume of soil needed to fill in forproject purposed is 35413m.

Hopefully can improved the quality of road inSarawak by performing good design, betteroption for road pavement, effective bridge anddrainage system design.
