Aggregate plays a very important role in the performance of highway pavements. Unfortunately, there are many areas where good quality aggregates are not available, and they have to be imported from far away quarries.
Use of weak aggregates in pavement construction has been a subject of interest world over, as it reduces cost and pressure on good quality aggregates. This book investigates a type of weak aggregate obtained from ordinary brick and over burnt brick to study its applicability in construction of sub-base course of flexible pavements and also to study the feasibility of using over-burnt bricks in lean cement concrete mixes.
The laboratory result included in the book consists of investigation of properties of over burnt bricks and improvement of strength of soil using different proportions of brick and over burnt brick aggregate. Repeated tri-axial test and CBR test result details on the soil and brick mixture are provided.
The construction of bituminous base and sub base courses for roads and runways of satisfactory stability and load carrying capacity requires the use of well graded, high quality gravel or crushed stones. As the supply of high quality granular material is decreasing and bitumen is no longer a cheap material in India, bituminous bases cannot be considered as economical. Over burnt brick is basically a waste product in preparation of brick. If such poor aggregates are used in granular or bituminous construction, the service life of the pavement will be greatly reduced. Therefore it was decided to include the feasibility of using over burnt brick in lean cement concrete mixes. Various mixes were selected with varying cement content. Besides compressive test, modulus of rupture, E-value and fatigue test results are provided. Author has presented pavement design examples with the laboratory test data.
