SOURCE: Fuel consumption measured: 04.11.1989-12.11.1989 with Toyota Highlux 4x4: northern sections (1 to 98)
Fuel consumption measured: 13.04.1990-16.04.1990 with Toyota Highlux 4x4: southern sections (1 to 25)
Volumetrical measurements by 'HESSAG Kraftstoffverbrauchtester 1000B/400B'
IRI values measured by Namibian Department of Transport: February 1984 to December 1989 (all sections)
Every fuel measuring point got 12 readings (2x2x3); altogether 75x12=900 points (54 sections).
NOTA: * Petrol 93 reached boiling point. Measurements are discarded because large variations and unrealistic
high values. Fractions of Namibian normal 93 octane petrol boil between 33oC and 188oC.
** Deep sand which required 4x4 wheel drive: high. Measurement has to be discarded.
Ch = Chainage = 100 feet chainage;
Pavement characteristics: See NOTA: table 7
Calculated fuel consumption (section 5.3.3.3): FC = 2,4*IRI + 110,4 (ml/km)
