Road Aggregate 101: Nominal maximum and/or 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. Commonly used aggregates i.e. 3. Unit : Kg/m 3 or lb/ft 3. Concrete made with this type of aggregate has a bulk density of 2300–2400 kg/m3. by Group 1 - WakandaSubject: Construction Materials and TestingInstructor : Engr. Essential Points. 2. AASHTO TEST METHODS CANNOT BE INCLUDED ON ODOT’S . Bulk Density = Weight of aggregate / Container of unit volume. The most recent Aggregate Base Course (ABC) unit weight test results performed by the NCDOT M&T Soils lab can be queried using this page. This test method is applicable to aggregates not exceeding 125 mm [5 in.] Normal-weight aggregate: An aggregate with a unit weight of 1520–1680 kg/m3 is classified as normal-weight aggregate.

Unit weight of steel 7850 kg/m3, cement 1440 kg/m3, sand (dry) 1540 to 1600 Kg/ m3, brick 1600 Kg/ m3, Aggregates 1750 kg/m3, bitumen 1040 kg/m3 The most common classification of aggregates on the basis of bulk specific gravity is lightweight, normal-weight, and heavyweight aggregates. in nominal maximum size. The variability in density can be used to produce concrete of widely different unit weights, see Table (1). TO GET COPIES OF THE TEST METHODS, YOU CAN ORDER A . Sand, gravel, and crushed rock belong to this category and are most widely used. ASTM Designation: C29/C 29M-07 . Heavy Weight Aggregate: Bulk Density (“Unit Weight”) and Voids in Aggregate . 4.1.3.5 Place the sample on a smooth, flat surface and mix … Road Aggregate 101: Gradation or distribution of different sized stones Open graded aggregate vs. well graded aggregate. 1.1 This test method covers the determination of bulk 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. Unit Weight of Water = 1000 litres/m 3 Required Amount of Water = 0.16362 X 1000 = 163.62 litres Therefore, we need 10.5 bags of cement, 0.5454 m 3 of sand, 1.09 m 3 of Coarse aggregates and 163.62 litres of water. HARD COPY OF ODOT’S MANUAL OF FIELD TEST … Normal Weight Aggregate: Produces concrete with unit loads ranging from 23 to 26 kN / m3 with a specific gravity between 2.5 and 2.7. THANK YOU! sand and gravel; crushed rocks such as granite, basalt, quartz, sandstone and limestone. Reporter: Noriel Mae E. Molde Weight in air of a unit volume of a permeable material. Unit Weight = mass/volume relationships Weight of the Material ----- Volume of the Material Unit Weight Definition Determination of Unit Weight of Aggregates Bulk It is the weight of aggregate needed to fill a unit volume of the container. DeLeon1st-semS.Y. It also indicates the aggregate grading and shape. DETERMINING UNIT MASS (WEIGHT) OF AGGREGATES TXDOT DESIGNATION: TEX-404-A CONSTRUCTION DIVISION 4 – 6 LAST REVIEWED: SEPTEMBER 2014 Note 1—Use standard gradation when dry loose unit mass fails the specification requirement at received gradation, and note this on the test report.
