Construction quality is crucial to the long-term pavement performance. Construction factors such as surface preparation, placement, joint construction and compaction/consolidation have an overwhelming effect on pavement performance, which cannot be ignored or compensated for in mix or structural design. Other construction considerations such as plant operations, mix transport and quality ...

layers. The rigid pavements are made of Portland cement concrete either plain, reinforced or pre-stressed concrete. The plain cement concrete slabs are expected to take up about 45kg/cm2 flexural stress. The rigid pavement has a slab action and is capable of transmitting the wheel load stresses through a wider area below.

Interlocking Cement Concrete Block Pavement. Interlocking cement concrete block pavement is another types of road pavement which consists of a layer of cement concrete paver blocks. The shape, size and strength for this block layer are specified. Generally, these blocks are laid over the soil subgrade which is well-compacted.

This design period is dependent on the nature and level of maintenance schedule. The design life may be taken as 10 to 20 years for low-traffic volumes (flexible pavements) and 20 to 30 years for high-traffic volumes, (rigid pavement) depending on the designer's discretion [IRC37-2001 and IRC58-2002]. 2.
Concrete's rigid design reduces the pavement's deflection and corresponding fuel consumption. Also smoothness of concrete pavements is less affected by seasonal changes, which could also contribute to lower fuel consumption. …
RIGID PAVEMENT A rigid pavement structure is composed of a hydraulic cement concrete surface course and concealed base and sub base courses. The surface course is the rigid layer and provides the majority of strength. While, in case of rigid …
