b. Shall closely monitor the activities of the District Maintenance Engineer toensure that the scheduled works (repair of defects and rectification activities)are prioritized and implemented.

a. Shall be directly responsible for the efficient and timely maintenance of all national roads and bridges within their respective jurisdictions;

b. Shall be held accountable for the proper expenditure of maintenance fundsand in the management of all other resources intended for the repair and maintenance of each road and bridge section in their area of concern;

c. Shall promptly submit to the Undersecretary for Technical Services, copy furnished the Director, Bureau of Maintenance, the names and latest picture of the MPPs and their respective assigned road section. Any changes in the assignment shall be submitted likewise to the above Offices.

a. Shall conduct inspection, at least twice a week, of the entire road section including the bridges subject of his/her assignment for the purpose of identifying and recording all noted defects and deficiencies;

b. Shall log results of inspection using Form MP-1 (Daily Road Inspection Report) which contains location of noted defects/deficiencies; estimated quantity, etc, and in which MP-1 shall be submitted daily to the Maintenance Engineer, copy furnished the District Engineer.

a. Shall assign technical personnel within his Office to regularly conduct actualfield inspections to validate if the MPPshad correctly logged and reportedthe location of the noted defects/deficiencies;

b. Shall immediately schedule rectification/repair works on thedefects/deficiencies noted by the MPPs, mindful of the response timeallowed for each defect;

c. As the DME's assigned technical personnel will conduct actual fieldinspections to regularly monitor the rectification/repair works to ensurequality and economic practicality of completed works, the DMEshall amongothers, order such works to be redone if the same is not to standards.

often occurs as a result of poor bonding or adhesion between layers

- edge of the bituminous surface is fretted, broken or Irregular.

- breakdown or disintegration of slab surface at edges, joints, corners or cracks. It is greater than or equal to 50mm wide, measured from the face of the joint or crack, with loss of material, or broken Into two or more pieces.

a depressed or broken part of a slab resulting from pavement cracking and disintegration of concrete.

Interconnected or interlaced cracks forming a series of small polygons resembling an alligator hide.

Deterioration of the upper concrete slab surface of more than 10mm affecting the whole slab.

is the bulging of the road surface generally parallel to the direction of traffic and/or horizontal displacement of surfacing materials, mainly in the direction of traffic where braking or acceleration movement occur.

refers to transverse undulations, closely and regularly spaced, withwavelengths of less than 2 meters

is a longitudinal deformation in a wheelpath. May occur in one or both wheelpaths of a lane

localized area within the pavement with elevations lower than the surrounding area. May not be confined to wheelpaths and could extend across several wheel paths.

seeping or ejection of water from beneath the pavement through cracks causing rocking, faulting and slab cracking.

is the vertical movement at a joint or crack under traffic

is the difference In elevation across a joint or crack creating a "step" deformation.

refers to shattered slab under this code.

This defect refers to the loss of or excess shouldering materials resulting on shoulder levelbeing lower or higher than the pavement level,

which is the difference in elevation between the edge of slab and shoulder; typically occurs when the outside shoulder settles.

- growth of grass on shoulders along secondary roads.

Growth of grass, weeds and shrubs or any kind of vegetation from the side of the canal to the RROW limits reaching an average height of 0.60 meters. This will indude trimming/pruning of trees In compliance with DO 93 s. 2014

Breaks on pavement occuring in variety of patterns ranging from isolated single crack to an interconnected pattern extending over the entire pavement surface.

- unconnected crack running transversely across the pavement/slab.

- unconnected crack running longitudinally along the pavement; can occur singly or as a series of nearly parallel cracks.

- interconnected cracks forming a series of blocks approximately rectangular in shape, commonly distributed over the full pavement. Cell sizes are usually greater than 1m.

- a crack extending diagonally from longitudinal edge to transverse joint

- unconnected crack diagonally across a pavement/slab

- unconnected irregular winding crack usually singular

- cracks on asphalt mirrored from the unsealed concrete weakened plane joint

Progressive disintegration of the pavement surface by loss of both binder and aggregates
