Road Surface Defects Assessment

Defects occurring within 300 mm from the edge are assessed as ________ break

Edge breaks are caused by the breaking away of the surfacing at the outside edges of the surfacing. This is often due to poor unpaved shoulder ________

The degree of edge breaking is rated by measuring the average distance from the edge of the pavement to the maximum points of ________

Short transverse cracks are initiated at the edge of the road and migrate ________

Drop-off is the step between the surfacing and the shoulder caused by ________

Edge breaking extending into the wheel path should be classified as ________

Table B.11 describes the degrees of surface deformation from degree ______ to degree 5

Degree 1 of surface deformation is visible but not felt in a ______ vehicle

Drivers avoid surface defects by selecting a different path and driving very slowly when the degree of deformation reaches ______

The Engineering assessment section provides guidelines for the evaluation of the current condition of the pavement structure as manifested through visible ______

The defects in the pavement structure can be caused by poor surfacing, ingress of water, traffic, climate, quality of material in pavement layers, and the ______ of the pavement

Cracking, pumping, deformation, patching, and failures/potholing are modes of distress indicating defects in the pavement ______

This section defines the summarised pavement condition and need information to be recorded by the ________.

A general rating for the condition of the pavement is useful for data ________.

The description of the overall condition of the pavement is given in Table B.27: Description of Degrees of Overall Condition of ________.

Very good condition is described as having very few or no ________.

Poor condition is characterized by a general occurrence of particular structural defects with degrees ranging from warning to ________.

Certain items requiring possible maintenance measures that are not recorded under standard defects should be noted on the assessment form, including problems such as service crossings (trenches), mechanical damage, mole damage, root damage, or any other problems not listed on the form. This information is found in TMH9: Visual Assessment Manual -B-51- Part B: Flexible ________.
