The minor arterial roads had an average asphalt layer thickness range of 91 - 99 mm 22 mm, against the designed thickness of 102 mm.Average values of relative dielectric constant of the asphalt layers were estimated in the newly constructed roads and its variation along the roads were used to locate potential low density section of the.
Asphalt pavement comprises the combined thickness of all asphalt courses as defined in clause 407.Asphalt regulating course asphalt regulating course is an asphalt course of variable thickness applied to the road surface to adjust the shape prior to the wearing course or any other bituminous surfacing or re-surfacing.
Establish the asphalt types, size and thickness of asphalt layers from the pavement design report and insert into the table.For regulation layers, insert the estimated range of thickness.If a pavement design report is not available, select the asphalt types from table 2a and the size of asphalt to suit the nominal layer thickness from.
All ministry numbered highways and ministry side roads with traffic volumes greater than 100,000 esals pavement design types a and b over the design period require a minimum thickness of 300mm of crushed base course cbc.Lower-volume side roads pavement design types c and d require a minimum thickness of 225mm of crushed base course cbc.
