The	growing population and urbanization throughout the	world	 need a infrastructure. Concrete	is considered chief construction material new even today.  It  is  believed	that  other than water the concrete is next most consuming material	throughout	the world. Concrete	not only is used	in buildings but also efficiently used in  the  construction of  highway pavements.		The manufacture of concrete  with  ordinary	ingredients causes the depletion of the natural	aggregate on the other hand the	waste produced	from	industries,	agriculture	and replacement	of old tires	etc causes divesting	environmental effects. Hence	the manufacture	 of  concrete with	used	or recycled	material	as aggregate	is one of the active areas of research of the day. There is increasing volume of end to life tires due to increasing use of vehicles worldwide.

The work presented is an experimental investigation m order to study the suitability of crumb rubber. Rubber tire used as fine aggregate in concrete. The parented studied are the workability, compression strength, tensile strength and skid resistance. Fine aggregate replaced by crumb rubber from 5% to 20% with
an increment of	5% specimens	of standard size
were	cast	and	tested as per standard procedure.The	resuIts normal concrete	without crumb purpose.  The  results	reveal the
strength also.  However  the skid Were compared with the relevant results of rubber which was also cast and tested for the decrease in workability, compression and tensile resistance of crumb rubber concrete is improved when compared to that of normal concrete which should increase the viability of
crumb rubber concrete to be adopted in the	pavements	particularly the	place where skid resistance is the major parameter of consideration  aDepartment of civil engineering faculty of engineering   uhttp://tinyurl.com/533z7b2h
