· density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination This test method is applicable to aggregates not exceeding 5 in [125 mm] in nominal maximum size
· Furthermore, the aggregates contained in a transport unit generally contain adsorbed moisture and surface (the latter affects the apparent density ), in contrast, this test determines the apparent density in the dry state includes a procedure to calculate the percentage of voids Between the particles of aggregate based on the bulk density determined to by This test method .
Essential Points. Most of the aggregates possess a relative density within – with a similar particle density about Kg/m 3 (150181 lb/ft 3).; Hereabouts, for coarse aggregates, the standard test process has been described in ASTM C 127(AASHTO), and for fine aggregates, the standard test practice has been described in ASTM C 128 (AASHTO).
· MoistureDensity Relations of Soils, Aggregates, and Specified Mixtures 1. Scope: This test is to establish the moisturedensity relationship of soils, aggregates and mixtures. NOTE: Before field control of compaction can be exercised, it is required that the optimum moisture, maximum density values (4point Method) be
or aggregate to the test maximum wet density of the same soil or aggregate when compacted by a specific test method. The procedures are presented in 2 parts: Part 1. Determine the inplace, wet density Part2. Determine the laboratory test maximum wet .
· Different types of field density test are being practiced in different parts of the world for evaluation of insitu soil compaction and knowing the relative degree of compaction. FDT which is acronym of Field Density Test is a Quality Control test carried out at site for knowing the increased density or compaction achieved at site ...

Recommended Values of Specific Gravity and Water Absorption for Aggregates. The specific gravity of aggregates normally used in road construction ranges from about to with an average of about Water absorption shall not be more than per unit by weight.

The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with onethird of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.
The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry test is named in honor of Ralph Roscoe Proctor [], who in 1933 showed that the dry density of a soil for a given compactive effort depends on the amount of water the soil contains during soil ...

· The SSD density, SSD relative density, and absorption are determined after soaking the aggregate in water for a prescribed duration. This test method is used to determine the density of the essentially solid portion of a large number of aggregate particles and provides an average value representing the sample.
The result is the ratio of the density of the aggregate to the density of water. The appropriate test method depends on the size of the aggregate being tested. For coarse aggregates the test is performed in accordance with AS or AS with aggregate that has been treated in a range of conditions such as dry and saturated surface ...
· Procedure The aggregate sample: The material for the standard test consists of aggregates sized mm to aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary.
Dense Bituminous Macadam (DBM) – Grading, Testing and Method of Construction. Dense Bituminous Macadam (DBM) is a binder course used for roads and highway works with a greater number of heavy commercial vehicles and a closegraded premix material vehicle and a closegraded premix material having a voids content of 510 percent.

Relative density (specific gravity) is also used in the computation of voids in aggregate in Test Method C29/C29M. Relative density (specific gravity) (SSD) is used in the determination of surface moisture on fine aggregate by displacement of water in Test Method C70.
