Jan 01, 1989 MATERIAL REQUIREMENTS Requirements for unbound aggregates to be applied in Portuguese roads are concerned with grading, Atterberg limits, sand equivalent and abrasion of coarse aggregate in the Los Angeles machine. Standards for the tests 276 that check these requirements are an adaptation of the corresponding ASTM standards.
Atterberg Limits and Indices. Atterberg defined the boundaries of four states of soil in the terms of limits. A fine-grained soil exists in different states depending on the amount of water in the soil system. The water content at which the soils change from one state to the other is known as consistency limits or Atterberg limit.
Road Aggregate 101 Nominal maximum andor minimum sized stone in mix The nominal size distribution of an aggregate specification is defined as the range of sieve openings through which 100 of the aggregate can pass.

fines of crushed solid structures to settled soil at various rates for example on 0, 30, half, and 70. The investigation additionally underscores the determination of different parameters of soil like moisture content and Atterberg limit at the various extent of demolished
Technician performing PI test. The PI is the difference between the liquid limit and the plastic limit PI LL-PL. Soils with a high PI tend to be clay, those with a lower PI tend to be silt, and those with a PI of 0 non-plastic tend to have little or no silt or clay.
Proper characterization of a dense-graded aggregate basesubbase material should include both quality and strength aspects. Gradation, passing the No. 200 sieve smaller than 0.075 mm fines content, and Atterberg limits for plasticity index PI are the most important properties that affect the quality and longevity of aggregates used as unbound layers in flexible pavement applications.
The liquid limit and plastic limit are called the Atterberg limits and represent the water content at which defined level of consistencies are achieved. ... operation that aggregate is used for, test number and aggregate type. Standard Test Procedures Manual STP 206-4

Atterberg Limits Test Procedure For all the Atterberg limits tests, soil samples consist of material passing a No. 40 425 m test sieve and are prepared for each test using wet or dry methods described in the standards. Moisture in Test specimens is adjusted by adding water, mixing with a spatula, and allowing to condition for at least 16 hours.

In this study, a well-graded crushed limestone was treated with SS-1hp type anionic emulsion bitumen. Several laboratory tests including gradation, Atterberg limits and compaction, i.e. moisture-density, were conducted on the virgin as well as emulsion stabilized base aggregate.
The combined effect of carbon black and crushed rock aggregates was investigated based on the compaction characteristics, Atterberg Limits, Particle size distribution and California Bearing Ratio ...

Also known as limits of consistency, Atterberg limits were first proposed by Atterberg 1911 8 9.

Atterberg limits are a basic measure of the critical water contents of fine-grained soils, such as silt and clay, as they transition from a solid to a liquid. Atterberg Limits are an inexpensive and well documented way of predicting the engineering properties of silt and clay soils. The Atterberg Limits are the shrinkage limit, plastic limit ...
