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

The surface course may consist of one or more bituminous or Hot Mix Asphalt (HMA) layers. These pavements have negligible flexure strength and hence undergo 

temperature to occur along Egnatia road which is 13 oC and one set at the almost Determine design thickness of the bituminous layers for the specified 

3/14 · The total thickness of compacted layer is generally kept 75 mm. This method is commonly used for strengthening of existing bituminous pavement. A suitable wearing course is provided over this layer before opening to traffic. 4. Premixed Type In this technique, the

More than 95% of the road infrastructure in India consists of flexible pavements with several Thicknesses of the bituminous layers vary from 200 to 250.

Seek advice from Roads and Maritime Pavements unit if a primerseal is to be used between an asphalt layer (greater than 50 mm thick) and a granular base.

Its thickness ranges from 50 mm to 100 mm. c. Base Course: Mainly, hard crushed aggregates are used in the construction of this layer. The base course is the
