Marshal test is extensively used in routine test programs for the paving jobs. The stability of the mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 600 °C. The flow is measured as the deformation in units of 0.25 mm between no load and maximum load carried by the specimen during stability test (flow value may also be

Followings are some different techniques and methods for reducing wear of rails....Use of special alloy steel, Good maintenance of track, Reduction of expansion gap, Exchange of inner and outer rail on curve, Use of lubricating oil on the gauge face, By coning of wheel, Reduction of the number of joints, interchanging inner and outer rails, Tilting of rails,

Hydraulic bench is a very useful apparatus in hydraulics and fluid mechanics. It is involved in majority of experiments to be conducted e.g. To find the value of the co-efficient of velocity ‘Cv’, coefficient of discharge ‘Cd’, to study the characteristics of flow over notches, to find metacentric height, to find head losses through pipes, to verify Bernoulli’s theorem

Something that is mixed or blended from two or more ingredients or elements before being used. This term is used usually for concrete in civil engineering. Sheet Asphalt: A premix of bitumen and sand (with or without filler) and containing coarse aggregate that exceeding 30%, laid in thickness varying from ¾" to ½" (dense carpet, stone metal is discarded and

Concrete is placed in the molds using a trowel in three layers of approximately equal depth and is remixed in the mixing pan with a shovel to prevent segregation during the molding of specimens. The trowel is moved around the top edge of the mold as the concrete is discharged in order to ensure a symmetrical distribution of the concrete and to minimize
