Influence of Recycled Waste High Density Polyethylene

Results of flexural strength indicates that the strength decreased systematically with increasing percentage of plastic content but remained the same with 2% and 4% replacement of coarse aggregate with waste HDPE. This may be due to decrease in adhesive strength between the surface of the waste plastic material and the cement paste.

Pavement materials Aggregates

Crushing test One of the model in which pavement material can fail is by crushing under compressive stress. A test is standardized by IS:2386 part-IV and used to determine the crushing strength of aggregates. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load.

Dec 19, 2019 The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength i.e. low crushing value should be preferred. Lower crushing value means higher strength as it indicates a lower crushed fraction under load.

The use of low grade and unsound crushed rock aggregates

Ghana and many developing countries have relied heavily, in the past, on hard granites and granitic gneisses for the production of rock aggregates and rock products for civil engineering works including the construction of roads and buildings. Experience in Ghana has shown however, that the quantity of crushed rock aggregates produced from hard rocks have proved insufficient for the needs of ...
