What is IRC SP 53 2019?




IRC SP 53 2019 is a standard published by the Indian Roads Congress (IRC), which is the apex body of highway engineers in India. The standard is titled "Guidelines on Use of Modified Bitumen in Road Construction (Second Revision)" and it was issued in October 2019. It replaces the previous version of the standard, which was published in 2010.


The purpose and scope of IRC SP 53 2019




The purpose of IRC SP 53 2019 is to provide guidance on the use of modified bitumen in road construction, especially for heavy traffic roads carrying overloaded trucks. The standard covers the following aspects:



  • The selection criteria and specifications of modified bitumen



  • The design methods and mix design procedures for modified bitumen mixes



  • The construction practices and quality control measures for modified bitumen pavements



  • The maintenance and performance evaluation of modified bitumen pavements



The scope of IRC SP 53 2019 applies to all types of roads, including national highways, state highways, urban roads, rural roads, and expressways. The standard also applies to all types of modified bitumen, including polymer modified bitumen (PMB) and crumb rubber modified bitumen (CRMB).


The main features and changes of IRC SP 53 2019




IRC SP 53 2019 has several features and changes that make it different from the previous version of the standard. Some of them are:

  • It provides a single specification for all types of modified bitumen, instead of separate specifications for PMB and CRMB.



  • It introduces new tests and criteria for modified bitumen, such as elastic recovery, force ductility, storage stability, softening point, penetration index, etc.



  • It updates the mix design procedures for modified bitumen mixes, based on the latest research and experience.



  • It recommends the use of warm mix asphalt (WMA) technology for modified bitumen mixes, to reduce energy consumption and emissions.



  • It incorporates the latest guidelines and best practices for construction and maintenance of modified bitumen pavements.



What is modified bitumen and why is it used in road construction?




Modified bitumen is a type of bituminous binder that has been modified by adding certain additives or modifiers to improve its properties and performance. Bituminous binders are commonly used in road construction as they provide strength, durability, flexibility, water resistance, and adhesion to aggregates.


The definition and types of modified bitumen




According to IRC SP 53 2019, modified bitumen is defined as "bituminous binder whose rheological properties have been altered by blending with suitable additives or modifiers". How to download IRC SP 53 2019 PDF for free?
