Highway engineering laboratory manual provides experimental knowledge to civil engineering students on the principles and procedures of testing the materials such as aggregates and bitumen used in highways construction. Various experiments covered in the manual includes I TEST ON AGGREGATES1. Specific gravity determination of the coarse aggregate sample2. Determination of abrasion value of the coarse aggregate sample.3. Determination of water absorption capacity of the coarse aggregate sampleII TEST ON BITUMEN4. Specific gravity determination of the bitumen/asphalt sample.5. Determination of consistency of the bituminous material.6. Viscosity determination of bituminous binder.7. Determination of softening point of the asphalt/bitumen sample8. Determination of ductility value of the bitumen sample9. Estimation of loss of bitumen on heating10. Determination of optimum binder content by Marshall methodIII BITUMINOUS MIXES11. Determination of stripping value of the bituminous mix Demonstration12. Determination of bitumen content in the bituminous mix by cold solvent extraction method.
