HIGHWAY MAINTENANCE

10.1 THE TECHNIQUE FOR HIGHWAY MAINTENANCE

The techniques for highway maintenance

Road maintenance is a continuous process that involves keeping and repairing of the existing road. So, it
is carried out to control the rate of damage and to ensure the safety towards the road users or the public.
The purposes on road maintenance:

i. To ensure the durability of road.
ii. To maintain the usage for the traffic user.
iii. To improve the traffic system operation.

The organizations that involve with road maintenance in Malaysia:

i. Federation Government by Highway Malaysian Boarded for highway link maintenance.
ii. Federation Government by Federation JKR for federation road link maintenance.
iii. State Government by State JKR, District JKR, Town Council etc. For local and state roads link.

Visual Assessment of Surface Conditions

Assessment of surface conditions is used by road authorities to:
i. Measure of the ability of the pavement to continue to provide the required service to the public
ii. Determine the inadequacies and deficiencies of pavements
iii. Determine the remedial measures to be taken; and
iv. Planning and programming of pavement maintenance and/or rehabilitation

In this assessment, pavement distresses are categorized and quantified. Distress in flexible pavement can
be categorized as cracks, surface deformations, surface defects, patches, potholes and edge defects.

Crack

Cracks results from partial or complete fracture of pavement surface. Cracks can be isolated or
interconnected. The damaging effects of cracks are: loss of water proofing layers, loss of load spreading
ability, loss of fines from road base due to pumping, loss of riding quality and loss of appearance.
