1) Preparing asphalt concrete specimens with varying bitumen contents and compacting them using a Marshall hammer.
2) Testing the specimens for properties like stability, flow, density and air voids to determine the optimum bitumen content.
3) The optimum bitumen content is taken as the average of the contents that produce maximum stability, maximum density and air voids of 4%.
4) Graphs of properties vs bitumen content are used to identify the optimum content meeting specifications.

Brihadaranyaka Upanishad, First Chapter Second Brahmin in Bengali (Bangla) la...debkumar_lahiri
In this Upanishad, the sage Yajnavalkya narrated the expansion and contraction of the Universe and its formation from the Universal Consciousness and the mysteries of Ashvamedha yajna. This is written in Bengali (Bangla fonts) with the original texts and meaning.This Upanishad explains the mysteries behind 'ashvamedha yajna'. This is based on the unification of the divinity and mortality as seen by the seers.
The document discusses methods for determining the load carrying capacity of pile foundations. The load carrying capacity has two components: skin friction and end bearing. Several methods are available to calculate skin friction and end bearing for cast-in-situ and driven piles. The document provides equations that can be used to calculate the ultimate skin friction and end bearing capacity for cohesive and cohesionless soils. The total ultimate load capacity is the sum of the skin friction and end bearing capacities. The design load capacity is calculated by dividing the total ultimate load capacity by a factor of safety of 4.0.

1. There are several bearing capacity equations proposed by researchers to estimate the load carrying capacity of shallow foundations.
2. For cohesive soils, the net ultimate bearing capacity is calculated based on the undrained cohesion of the soil, depth of the foundation, width and length of the foundation.
3. For cohesionless soils, the allowable bearing capacity is calculated using the corrected SPT value, depth factor, width and length of the foundation, and tolerable settlement depending on if the width is less than or greater than 4 feet.

Biochemical oxygen demand (BOD) measures the amount of oxygen required by microorganisms to break down organic material in water, while chemical oxygen demand (COD) determines the oxygen required to oxidize organic and inorganic chemicals in water. COD values are higher than BOD values because COD accounts for both biodegradable and non-biodegradable substances, whereas BOD only considers biodegradable materials.
