PAVEMENT CONDITION INDEX 101

PAVEMENT CONDITION INDEX 101 There are two ways to measure the condition of a road network The first way is to call it the Squeaky Wheel, sit back and wait for the complaints The more complaints, the worse the condition of the roads The second way is to use a more thorough, comprehen-sive and pro-active approach to review the entire road.

Evaluation and Rating of Gravel Roads

ROAD CONDITIONS AND DEFECTS A gravel road is best given an overall rating through obser­ vation of individual defects These defects can be combined to provide the information necessary to make an overall assessment of road conditions This system will consider three primary conditions: crown, drainage, and gravel layer, along.

Review of remote sensing methodologies for pavement

Unpaved roads are typically constructed using a mixture of gravel placed and compacted over finer-grained soil such as clay or silt (or mixtures of these soils) (Fig 1 a) The finer-grained soil may be naturally deposited as part of the geological cycle or constructed as a fill as part of an artificially constructed structure such as an embankment or on top of an earth retaining structure.
