The document outlines various tests conducted in highway engineering, including soil subgrade tests like the California Bearing Ratio test, aggregate tests such as the Los Angeles Abrasion test and Impact test, bitumen tests like the Penetration test and Ductility test. Diagrams are included showing the apparatus and procedures for tests like the CBR, Los Angeles Abrasion machine, and softening point test. The document was created by an engineering student to explain common material testing methods used in highway projects.
