Design Of Cement Concrete Pavement Irc

This construction is used specifically for highway concrete pavements and for airport runway pavements as it can take heavy loads.

Design of cement concrete pavement irc.

Irc 73 1980 geometric design standards for rural non urban highways 120 00 20 00 72. The stresses induced in concrete pavements are mainly flexural. In this case the load carrying capacity is mainly due to the rigidity ad high modulus of elasticity of the slab slab action. Rigid pavement design as the name implies rigid pavements are rigid i e they do not flex much under loading like flexible pavements.

Guidelines for the analysis and design of cast in place voided slab superstructure first revision 183. Thickness design 6 jointing 7. Subgrades and subbases 2. Therefore flexural strength is more often specified than compressive strength in the design of concrete mixes for pavement construction.

3 2the mechanistic empirical design approach which was used in the second and third revisions of irc 37 is retained in the current revision as well for the design of flexible pavements. Construction of cement concrete roads. Irc 75 2015 guidelines for the design of high embankments first revision 935 00 40 00 74. Guidelines for the use of interlocking concrete block pavement.

Following are the factors involved in the design process for concrete streets. They are constructed using cement concrete. Critical load positions since the pavement slab has finite length and width either the character or the intensity of maximum stress induced by the application of a given traffic load is dependent on the. 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.

Street classification and traffic 4. The theory selected for the analysis of pavements is linear elastic layered theory in which the pavement is modeled as a multi layer system. Guidelines for design and construction of cement concrete pavements for low volume roads first revision 181. A simple method of concrete mix design based on flexural strength for normal weight concrete mixes is described in the paper.

The stresses induced in concrete pavements are mainly flexural. Check out the mix design for concrete roads as per irc 15 2011. Construction specifications sub wades and subbases unlike o er paving materials the structural strength of a concrete pavement is largely within the concrete itself. 62 may be referred to for the design of low volume rural roads.

Therefore flexural strength is more often specified than compressive strength in the design of concrete mixes for pavement construction.
