The paper draws attention to the major differences in design methodology of flexible and rigid pavement designs. For concrete pavements, the design is based on the Equivalent Strength (CBR) of 1000 mm of subgrade. This includes the Selected Material Zone (SMZ) and is calculated using the widely accepted Japanese Public...

Diamond Grinding of Concrete Pavements
This presentation was part of a Forum presentation entitled “Concrete pavement construction equipment – batch plants, slipformers, diamond grinding”. It summarises that … Grinding improves ride quality improves microtexture improves macrotexture (albeit longitudinal) reduces tyre noise Grooving has no impact on ride quality has no impact on microtexture (hence no...
