California Bearing Ratio method is an empirical method of design of flexible pavement developed by California Division of Highways, in 1928 for the design of Roadways, Railways and Airfield. In order to design a pavement by CBR method, the soaked CBR value of soil is evaluated which takes aroun...
The CBR value is the stress at the 0.100in (2.54mm) penetration depth. Occasionally, the ratio at the 0.200in (5.08mm) penetration depth is higher than the 0.100in depth, and the test must be rerun. If the check test shows similar results, the stress from the 0.200in penetration depth ...

"Riders who want a chilled-out Ducati sportsbike will love the SuperSport S, and rightly so as it has all the character, feel and sporting prowess you expect from a Bologna bike, but in terms of value it can’t match the Honda. Even the base model, without the Öhlins, is £...
CBR tests were performed at three thicknesses of the sand base layer for both soaked and unsoaked conditions. The obtained results show that the threshold value of sand layer thickness is dependent on the strength of subgrade clayey soil, which is dependent on the compaction moisture and soaking...
CBR valueThe unbound granular materials (UGM), base and subbase layers, play an essential role in the overall structural performance of thin pavement structures. They show complex stress dependent elasto-plastic behaviour under external loading. Therefore the UGM are commonly tested using the Repeated...

The net result, with the Fireblade SP in stock race trim, is a best-in-class drag coefficient value of 0.270. Winglets To generate downforce at track speeds – and maintain the smallest possible frontal area – the fairing also employs winglet structures that effectively generate the same downfo...
