The surface course is the rigid layer and provides the majority of strength. Conclusions/ summary as per the above discussion of pavements (rigid and flexible pavement) by many researchers some conclusions or summary is drafted which are as follows: But the initial costs are somewhat high.
Types of Pavement Road Surface Structural Engineering
775.5 kn + 1574.5 kn.
These findings are consistent with research at massachusetts institute of
Functions •good riding surface •resistance to weathering and vehicle load conditions •structural stability to. This paper presents the results of pavement (plateau) dimensioning, designed for traffic of heavy vehicles (dump trucks) exclusively with a weight of 2,350 kn, ie. 25 rows rigid pavement is beneficial because of its durability and low maintenance cost. The cost of flexible pavement per kilometer was found outto have 7.9 million etb more than the rigid pavement because of the incurring costs of maintenance through its design life.therefore, it is suggested that portland cement concrete pavement shall be used in (pccp) pavement construction to cater local material requirements.
Based on design considerations there are two types.
Two variant solutions for flexible and rigid pavement are given,. Rigid pavement carries higher flexural strength than flexible pavement i.e. A short summary of this paper. Less maintenance cost and continuous traffic and flow.
Flexible pavement have low completion cost but repairing cost is high.
Flexible pavement, on the other hand, provides high riding quality but has reduced life and needs maintenance. Rigid pavement has a concrete layer at the top, the base course and soil subgrade are under it. Pavement designs •composition of road pavement: Pavement design methods, developing guidelines with a protocol for considering rigid versus flexible pavement designs when allowed alternate bids, and developing the alternate pavement design analysis tool (apdat) for pavement type analysis.
Flexible pavement designs when allowed as alternate bids:
Flexible pavement designs when allowed as alternate bids: It carries bending and deformation without rupture under wheel axial load. Rigid pavement has a high flexural strength. Its durability is double or triple of flexible pavement which makes it very economical in the long term view.
Rigid pavements are constructed from cement concrete or reinforced concrete slabs.
In the long run it is about half the cost to install and maintain. Rigid pavements provide very poor riding quality and are only used in special requirements. If you are planning to construct the road on your property or surrounding then we prefer you to choose rigid pavement. Rigid pavements have high flexural strength than flexible pavements due to.

Rigid pavement has the ability to bridge small imperfections in the subgrade.
In simple terms, a flexible pavement can be defined as a pavement layer comprising of a mixture of aggregates and bitumen, heated and mixed properly and then laid and compacted on a bed of granular layer. On rigid pavements use 3.2% less fuel compared to flexible pavements. The total thickness of the pavement is lesser than flexible pavement. Rigid pavement can distribute the load over a wide area because of its high flexural strength.
Following are some adverse conditions that require us to choose rigid pavement over flexible pavement:
Load transfer is done by slab action. Inflexible pavement, the load is transferred by grain to grain contact.
