AN INVESTIGATION INTO QUALITY OF AGGREGATE IN ROAD 7 LAB TESTS ON AGGREGATE TO CHECK QUALITY FOR USE IN

AN INVESTIGATION INTO QUALITY OF AGGREGATE IN ROAD CONSTRUCTION ABSTRACT The current extensive use of low quality aggregate in Nigerian road for engineering applications is of concern because their appear to be a level of ignorance surrounding their existing properties and implications This project was conceived for the purpose of comparing the crushed aggregate deposits in Isi Agu Sep 12 32 Tests on Aggregate Aggregate plays an important role in pavement construction Aggregates influence to a great extent the load transfer capability of pavements Hence it is essential that they should be thoroughly tested before using for construction Not only that aggregates should be strong and durable they should also possess proper shape and size to
