Webcollected from depths of about 2-3 feet and laboratory tests for LL, PL, PI, particle size distribution, OMC, MDD and CBR values (both soaked and unsoaked) have been performed on these samples at Geotechnical Laboratory, according to AASHTO and ASTM specifications [11-14]. The soil classifications of these samples have been done WebThis test method sets out the procedure to determine the California Bearing Ratio (CBR) of road construction materials. The specimens are compacted and tested in a laboratory. NOTE: This method is adapted from AS 1289.6.1.1. ... OMC according to T111 but using a -19 mm portion (b) Calculate the LMR according to Step 6(b)
Predicting Soaked CBR Value of Fine Grained Soils Using Index …
Web29. avg 2016. · CONCLUSION Based on above test results and discussions the following conclusions may be made From simple correlation method CBR can be predicted by soil properties. Liquid limit is considered as higher priority for predicting soaked CBR value followed by OMC, MDD and PI based on assessment factor R2 . CBR correlated with … Web08. feb 2024. · The particle-size distribution curve and California Bearing Ratio (CBR) values of all the blends met the minimum requirements. Results of RLT tests confirmed that all the nominated blends were found to provide the resilient modulus value required to be used as pavement materials. ...

Predicting the California Bearing Ratio From Compaction and ...
WebOMC. CBR value decreases with increase in OMC but also increases with increase in MDD and grain size. From regression analysis the coefficient of variation (adjusted R2) for the CBR value is found to be 0.998. From the formula and table 2, we can conclude that the correlation equation can be Web24. avg 2024. · From then on the curing times for some soils when undertaking CBR testing was extended to reflect the difference between the Field Moisture Content (FMC) of a soil and its Optimum Moisture Content (OMC). The changes to the Australian Standard mean that depending upon the FMC to OMC difference and the Liquid Limit (LL) of the sample, … Web26. apr 2024. · Unsoaked CBR test was conducted on specimens compacted at optimum moisture content (OMC) and at 2% wet and dry sides of OMC, whereas soaked CBR test was conducted only on specimens compacted at OMC. CBR value increases with penetration depth up to 5.08 and 7.62 mm under unsoaked and soaked conditions, … hydro cleaning pipes
