They should rest on a non-rigid surface which has enough uniform bearing capacity.
It is necessary that the rigid pavement rests on a non-rigid surface.Ĭlarification: The design approach for rigid pavements is that it has to satisfy two conditions. The availability of material can be checked and if there is any possibility of recycling, it should be taken into account.Ĩ. Which of the below is not a secondary factor to be considered for the pavement design process?Ĭlarification: The recycling opportunity is considered to be a type of primary factor in the design process of the pavement. 80/100 is used in moderate conditions, 30/40 in cold conditions and 50/60 can be used in hot/moderate type climate.ħ. What grade of bitumen must be used for the construction in a hot climatic condition?Ĭlarification: The grade 60/70 must be used for the construction in hot climatic conditions. The flexible pavement is considered to be a layered system and each layer is evaluated.Ħ.
#IIT PAVE SOFTWARE SOFTWARE#
What is the structural analysis of flexible pavement using IIT Pave based on?Ĭlarification: The structural analysis of pavement using IIT Pave software is based on multi-layer theory.
This gives an idea of the traffic that is to be catered for and the design method can be chosen accordingly.ĥ. What is the formula used for the computation of design traffic?Ĭlarification: (N=frac×A×D×F) is the right formula used to compute the design traffic for the design of pavements. IRC 37 is used for flexible pavement design and IRC SP 37 is used for obtaining load-carrying capacity of bridges.Ĥ. IRC SP 58 is a handbook for use of fly ash in roadways. The characteristics of concrete used in the pavement design should be according to which code?Ĭlarification: IRC 58 gives the design of plain jointed rigid pavements. The pavement construction includes the construction of various pavement layers.ģ. The earthwork consists of excavation and embankment construction. The two stages are earthwork and pavement construction. There are two stages involved in the construction of a new road.Ĭlarification: The construction of a new road can be divided into two stages. Pensolve is an engineering spreadsheet review software.Ģ. Plaxis is used for design and analysis of deep foundations, tunnels and dams. The software uses the available data to do the structural analysis of the pavement. Which software can be used for the structural analysis of the pavement?Ĭlarification: IIT Pave is a software that has been developed by the Indian Institute of Technology. Pavement Design Questions and Answers for Entrance exams on “Pavement Design Process – 2”.ġ.
