alia, by factors like traffic, soil type and rainfall, following the technical
specifications laid down in the Rural Roads Manual (IRC:SP20:2002).
Normally rural roads would need to be designed to carry upto 45 commercial
vehicles per day (CVPD) only. All cases of design for new construction
where a higher traffic is projected need detailed justification. In the case
of new construction for eligible Habitations of population below 1,000
where traffic expected is likely to remain very low (below 15 CVPD), in the
interest of economy, the road would generally be designed for a gravel or
other unsealed surface as provided in the Rural Roads Manual, subject to
considerations of rainfall. In case of new construction to connect Habitations
with population below 500 where the projected traffic growth is likely to be
very low, the carriageway may further be restricted to 3.0 m.
(iii) Where the road passes through a Habitation, the road in the built-up area
and for 50 metre on either side may be appropriately designed preferably
as a Cement Road or with Paved Stones, besides being provided with side
20 drains. Appropriate side drains and cross drainage will be provided, so that
improper drainage does not damage the road or the dwellings alongside.
(iv) Wherever local materials, including Fly Ash, are available, they should be
prescribed subject to adherence to technical norms and relevant Codes of
Practice.
(v) Rural Roads constructed under PMGSY must have proper embankment
and drainage. Adequate number and type of Cross Drainage (CD) works,
including causeways, where appropriate, must be provided based on site
requirements ascertained through necessary investigations. Minor bridges
(of single lane specifications only) may be provided where necessary. In
case the length of an individual bridge exceeds 15m, a separate DPR will
be prepared after site inspection jointly by the Superintending Engineer
and the State Technical Agency. In case the length exceeds 25m, the
project will be separately executed by the engineering division of the State
