Percent Fractured Face Test. A sample retained on the mm (No. 4) sieve is collected and the number of particles with fractured faces is compared to the number of particles without fractured faces. A fractured face is defined as an "angular, rough, or broken surface of an aggregate particle created by crushing, by other artificial means ...
Mar 28, 2021 · Aggregate Crushing test (IS 2386 (Part 4):1963 BS 812–110:1990) Aggregate crushing test values indies the strength of aggregate and hence it is very significant. Similarly we can say crushing value is the relative measure of resistance of an aggregate under gradually applied compressive loads. Higher crushing strength means lower ...
Aggregate Crushing Value (ACV) test indies the resistance to crushing under gradually applied crushing load. It is measured as percentage of aggregates passing through mm IS sieve after specimen subjected to a compressive load of 40 tonne at the rate 4 tonne per minute and to the weight of aggregates taken.
Aggregate crushed value(ACV), determined in accordance with TMH1 method B1, shall not exceed the appropriate value in the 3602/3. DURABILITY The material shall comply with the requirements in columns 3,4 and 5 of table 3602/2. FLAKINESS INDEX Flakiness Index, determined in accordance with TMH1 method B3, shall not exceed
"Pavement and Materials Design Manual" prepared by the United Republic of Tanzania Ministry of Works 1999, and on relevant ERA and TRL publiions. Available information has been modified to provide a simple procedure to design gravel wearing courses and low standard roads, which is appropriate to Ethiopian conditions. Gravel road pavements are

Aggregate. Aggregate" is a collective term for the mineral materials such as sand, gravel and crushed stone that are used with a binding medium (such as water, bitumen, portland cement, lime, etc.) to form compound materials (such as asphalt concrete and portland cement concrete). By volume, aggregate generally accounts for 92 to 96 percent ...
Jul 17, 2021 · Crushing Test. One of the model in which pavement material can fail is by crushing under compressive stress. A test standardized by IS:2386 partIV 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.
Aug 27, 2019 · The values of aggregate crushing test agree in general with that of aggregate impact test. The crushing strength test is most significant as far as the conditions to which the aggregates is likely to be subjected in practice are concerned. The suitability of aggregate in the pavement layers is dependent upon the type of road construction.
