(ix) Location of water bodies (lakes and reservoirs), at everyoccurrence; and,(x) Height of embankment or depth of cut @ every 200m andevery change of feature whichever is earlier.(xi) Land width i.e. ROW;(xii) Culverts, bridges and other structures (type, size, spanarrangement and location);(xiii) Roadside arboriculture;(xiv) Existing utility services on either side within ROW;(xv) General drainage conditions(xvi) Inventory of all road side facilities for the publicincluding educational, health, communication facilitiesand road user based facilities such as tea shops, dhaba,vehicle service shops etc4.9.3.1.2 The data should be collected in sufficient detail. The datashould be compiled and presented in tabular as well as graphicalform. The inventory data would be stored in computer files usingsimple utility packages, such as EXCEL.4.9.3.2 Pavement Investigation4.9.3.2.1 Pavement Composition1. The data concerning the pavement composition may bealready available with the PWD. However, theconsultants shall make trial pits to ascertain the pavementcomposition. The test pit interval will be as per Para4.9.3.2.4 (iv) below.2. For each test pit, the following information shall berecorded:(i) test pit reference (Identification number,location):(ii) pavement composition (material type andthickness); and(iii) subgrade type (textural classification) andcondition (dry, wet)4.9.3.2.2 Road and Pavement Condition Surveys1. Detailed field studies shall be carried out to collect roadand pavement surface conditions. The data shouldgenerally cover:(i)pavement condition (surface distress type andextent);ADB-IV41

(ii)(iii)(iv)shoulder condition;embankment condition; anddrainage conditiona. Pavement• cracking (narrow and wide cracking), % ofpavement area affected;• ravelling, % of pavement area affected;• potholing, % of pavement area affected;• edge break, length (m); and,• rut depth, mmb. Shoulder• Paved: Same as for pavement• Upaved: material loss, rut depth andcorrugation,• Edge drop, mm.c. Embankment• general condition; and• extent of slope erosiond. Drainage• General condition• Connectivity of drainage turnouts into thenatural topography• Condition in cut sections• Condition at high embankments2. The objective of the road and pavement conditionsurveys shall be to identify defects and sections withsimilar characteristics. All defects shall be systematicallyreferenced, recorded and quantified for the purpose ofdetermining the mode of rehabilitation.3. The pavement condition surveys shall be carried outusing visual means. Supplemented by actualmeasurements and in accordance with the widelyaccepted methodology (AASHTO, IRC, OECD, TRLand World Bank Publications) adapted to meet the studyrequirements. The measurement of rut depth would bemade using standard straight edges.4. The shoulder and embankment conditions shall beevaluated by visual means and the existence of distressmodes (cuts, erosion marks, failure, drops) and extentADB-IV42
