concrete roads: pqc, methods of construction and how it is,pavement quality concrete (pqc) is cement concrete made with large size aggregates 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. construction of cement concrete roads:.construction of cement concrete road,equipments used a list of tools, equipment and appliances required for the different phases of concrete road construction is given below three wheeled or vibratory roller for compaction purpose shovels, spades and sieving screens concrete mixer for mixing of concrete formwork and iron stakes watering devices - water lorries, water carriers or watering cans wooden hand tampers for concrete.

precast pre-stressed pavements concrete roads are designed to resist flexural loading conventional concrete pavements from traffic loading and crack control from a host of roller compacted pavements processes such as drying shrinkage, curling and warping pervious or porous concrete pavement (acpa, 1992; delatte, 2008).
design and construction of joints for concrete streets to ensure that the concrete pavements we are building now will continue to serve our needs well into the future, it is essential to take into account all design and construc tion aspects. this includes thickness design, subgrade and subbase preparation, and jointing. this publication

design of mix for concrete road. design of mix refers to statements by which various aggregates and asphalt cement is to be mixed to yield a mix possessing desired qualities and characteristics these qualities are as follows: sufficient asphalt to ensure durability of the pavement.
durability. concrete roads are more durable than asphalt roads, whereas asphalt roads are less durable than concrete roads.. effect of weather. with varying water table levels and varying rainfall conditions across the indian geography concrete road emerged as a more durable and sturdy option.. since asphalt roads are known to get eroded by water, whereas heavy rain and other extreme weather

thickness is the major factor (even more than the strength of the concrete) in determining a driveway's structural capacity. place concrete at a minimum thickness of 4 inches. increasing the thickness from 4 inches to 5 inches will add approximately 20% to your concrete cost, but will also boost your driveway's load-carrying capacity nearly 50%
