A standard brick ( dimensions 200mm x 100mm x 65mm) is compressed lengthwise by a force Pas shown. If the ultimate shear stress for the brick is 8MPA, that occurs at an inclination of 45° with the horizontal, and the ultimate compressive stress is 26 MPa, what is the axial deformation of the brick? Modulus of elasticity of the brick is 2.65 GPa. 200 mm 100 mm 65 mm

Asphalt Binders and Mixtures

Asphalt binders are subsidiary products procured during the refining process of petroleum while manufacturing gasoline, diesel, and similar petroleum products. Asphalt binders are obtained from the residue that remains after the distillation of petroleum, this residue is further subjected to steam distillation and oxidation to remove the traces of gas oil present in the residue. Certain additives or modifiers are also added to asphalt binders to alter them to suit different applications.
