Abstract |
|
RBI grade-81 have a good potential to reduce the cost of pavement layers if weak sub-grade is encountered on the alignment. On low volume paved roads, designers should consider the installation of RBI grade-81 to improve the California Bearing Ratio. Reduce layer thickness and increase a structural number of pavement. RBI grade-81 support gave in a solitary or multilayer to sublevel expands the quality of the dirt and in this way decrease the thickness of asphalt; thus reducing the cost of pavement construction. AT CBR value of 3%:- Total pavement thickness for CBR 3 % and traffic 5.5 MSA from IRC: 37 2012 PLATE 1 = 697 mm. AT CBR value of 15%:- Total pavement thickness for CBR 15% and traffic 5.5 MSA from IRC: 37 2012 PLATE 16 = 471.5 mm. Total 47.82% material saving from my study shows that. |
