(DOC) AGGREGATE IMPACT VALUE TEST | hong g.woei

The aggregate impact value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, lower aggregate impact value should be preferred. Toughness is the property of a material to resist impact. Due to traffic loads, the aggregate are subjected to the pounding action ...

Aggregate Water Absorption Test. Water absorption gives an idea of strength of aggregate. Aggregates having more water absorption are more porous in nature and are generally considered unsuitable unless they are found to be acceptable based on strength, impact and hardness tests. Water absorption shall not be more than 2% per unit by weight.

The LA abrasion test was originally developed in the 1920s to provide a quantitative method for evaluating the quality of pavement materials (Prowell et al., 2005, Kahraman and Fener, 2007).Over time, as the LA abrasion test was incorporated into various global standards, several attempts were made to investigate the relationship of the LAV to alternate methods.

Impact Testing

2021-9-7 · Impact tests are used in studying the toughness of material. A material''s toughness is a factor of its ability to absorb energy during plastic deformation. Brittle materials have low toughness as a result of the small amount of plastic deformation that they can endure. The impact value of a material can also change with temperature.
