Impact of Diamond Grinding on Rigid Pavement

Diamond grinding is a rigid pavement preservation treatment which is typically utilized to increase pavement smoothness by eliminating the surface undulations. The focus of this study is to evaluate the impact of diamond grinding on rigid pavement performance by using the mechanistic-empirical procedure. The effectiveness of a diamond grinding was assessed by evaluating the IRI before and

Diamond Grinding Pavement Interactive

Diamond grinding addresses serviceability problems but not their root cause. For example, diamond grinding can substantially reduce the roughness on a faulted rigid pavement, but it will not address the cause of faulting, nor will it prevent roughness in the future as a result of additional faulting.

Rigid Pavement Construction Of Rigid Pavement

The pavements having high flexural strength is called rigid pavement. It is simply a concrete road that may be either RCC or PCC. Rigid Pavement is divided into different slabs during construction and a small gap is provided between the slabs so that concrete doesn’t crack during expansion in summer days. Unlike flexible pavements; rigid pavement acts as a slab and is capable of transmitting wheel

Difference Between Flexible And Rigid Pavement

1- Rigid pavement has a good flexural strength which serves as the major factor of design. 2- Rigid pavement has a concrete layer at the top, the base course and soil subgrade are under it. 3- Rigid pavement can distribute the load over a wide area because of its high flexural strength. 4- Load transfer is done by slab action. 5- The total thickness of the pavement is lesser than flexible
