| II. PAVEMENT ENGINEERING AND PAVING MATERIALS
3. RIGID PAVEMENTS
In this sub section, total 7 projects comprising of 4 completed projects and 3 on going projects have been reported. Research work reported in the area of rigid pavements comprises of evaluation of Wollastonite in concrete works, Use of High volume fly ash in pavements, studies on flakiness and elongation indices of aggregates in different layers of pavements and high performance fibre reinforced concrete for construction and repair of concrete pavements. Use of sulfonated melamine formaldehyde super plasticizer and fly ash in concrete roads has also been reported.
|SALIENT POINTS FOR DISCUSSION|
|1. Techno – economic feasibility of use of Wollastonite in concrete works|
|2. Effect of flakiness and elongation indices of aggregates in different layers of pavements|
|3. Construction, quality control and performance of High volume fly ash concrete roads|
|4. Need to promote use of fly ash in pavements|
