PQC stands for Pavement Quality Concrete (PQC) Grade of PQC is Generally M40 and it is designed as per IRC:15-2002. PQC is used for the construction of Concrete roads as a top layer . Generally Top layer on the highway having thickness of 300 mm. Quality Concrete (PQC) is cement concrete made with large size aggregates 37.5 mm nominal size in accordance with IRC specifications and laid over a dry lean concrete sub-base. This construction is used specifically for highway concrete pavements and for airport runway pavements as it can take heavy loads.

Thus PCC road may be M25-M30 concrete and 20 mm nominal size of aggregate, generally use for low volume road,PQC shall not be consider as RCC because aggregate size for RCC work is to be restricted to 20 mm

Expansion joint are maid by Inserting a Compressive fiber sheet thickness of 25 mm,now we discuss Construction joint..I want to said that when work is going to end the joint we will make there it shall be expansion type..location of this type joint may be every 30 mtr or where work will end whichever is less.Now discussed Contration joint..these type joint width shall be less 5 mm In some roads we also provide Dowell bars is this joint without Compressible sheet, the joint where Dowell bar are inserted we cut groove by Sawing machine over this,Space between two contraction joint depend on lane width if lane width of pqc is 4 m. Then location of joint shall be evry 4 m. Intervals..if lane width is 3.5 m. Then joint distances should be 3.5 m....I want to said that length and width ratio will be 1
