physical properties or strength parameters of soil subgrade. An empirical approach is one which is based on the results of experimentation or experience. An empirical analysis of flexible pavement design can be done with or with out a soil strength test. An example of design without soil strength test is by using is HRB soil classification system‚ in which soils are grouped from A-1 to A-7 and a group index is added to differentiate soils within each group. Example with soil strength test uses McLeod

stress of 670MPa. 2 METHODS Five samples of cold-rolled steel of 50mm gauge length‚ 3mm thickness and 12.5mm width are tested to AS 1931-2007 Metallic Materials – Tensile Testing at Ambient Temperature with SHIMADZU Tensile Strength Tester Machine. Fig 1. SHIMADZU Tensile Strength Tester Machine. The data is collected in the sense of Applied Load (N) vs. Displacement (mm). Average Applied Load and Displacement from all five specimens is then used to calculate the Stress (MPa) and Strain. Stress/Strain

strong‚ light‚ and rustproof which is what makes it so important and diverse. The original application for this metal was in the military aerospace industry specifically because of its efficiencies in structural qualities‚ a result of titanium’s strength and density. It has become the metal of choice for many different applications. According to Titanium Industries‚ Inc.‚ Titanium was actually first used in dentistry in the 1940’s. Today titanium is routinely utilized in the dental industry for
