6/14 · 2. Bitumen Carpet Road. In the construction of bitumen carpet road the recommended bitumen binder is 80/ 100 grade and the tar required should be of grade RT-3.

334-1.4 Thickness: The total thickness of the Type SP asphalt layers will be the plan thickness as shown in the Contract Documents. Before paving, propose a thickness for each individual layer meeting the requirements of this specification, which when combined with other layers (as applicable) will equal the plan thickness.

Hot rolled asphalt roadbase has been discontinued. Whilst a design based on DBM50 is the norm, information has been provided so Contractors can offer other thickness of other asphalt materials. (Note: The term asphalt is now used for all bitumen bound materials) • Hot Rolled Asphalt wearing course has been substituted with Thin Surfacing

Answer (1 of 2): After the development of mechanistic empirical design approach it depends up on your material and climate but typically it varies between 2 to 6 inches for normal

In the construction of bitumen carpet road the recommended bitumen binder is 80/ 100 grade and the tar required should be of grade RT-3. The 

ElektroPhysik’s asphalt layer thickness measuring device StratoTest 4100 doesn’t use with the standard core drill method which damages the construction layer. Thanks to its innovative measuring procedure, measurements of asphalt, slag, gravel and concrete layers in road construction and the concrete layering in landfill construction work are performed with ease
