 · A rigid pavement, as the name implies, is a type of pavement that stays like a rigid slab under the loading. The rigid slab bridges the low-bearing or poor compacted soil. So, rigid pavement is an ideal pick if you have poor bearing soil or the loading is heavy. Normally, civil engineers construct rigid pavement with un-reinforced or plain ...

 · Based on this background, we evaluated the effectivity of fly ash substitution in lightweight concrete as a material in rigid pavement construction based on the compressive strength requirements at 28 days of age. This study used a mixture of Portland cement type I and to produce lightweight concrete with a specific gravity of 1.2.

The Mumbai-Pune Expressway, the first access-controlled expressway in the country, witnessed first large-scale application of concrete for highways in India. This project represents about 100 km of six-lane concrete pavement - a staggering 800,000 m3 of concrete executed in a time span of 2-2 and a half years.
