From the experiment the value is 29.2 29.8 and 29.8 are close to the maximum allowable limit for good aggregates. Hence they can be acceptable as their Aggregate Impact value is less than 30. Aggregate ImpactValues AIVs below 10 are regarded as strong and AIVs above 35 would normally be regarded as too weak for use in road .

Impact testing of the base metal is not required if the design minimum temperature is warmer than or equal to the calculated value of MDMT. However for steels impact testing is not required if the stress ratio r 323.2.2 b is 0.3 or less and the design minimum temperature is warmer than or equal to −104 C −155 F and temperature reduction may be used if 323.2.2 c rules are .
The allowable temperature reduction determined from Fig. UCS-66.1 . production welds including at least 80 of the aggregate times at temperatures. . that the weld metal impact test values shall be at least as high as those for the base material. This paragraph may place an additional limit on the qualification thickness of a

Jul 01 2019 The apparatus of the aggregate impact value test consists of A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. Level and plane concrete floor of minimum 45 cm thickness are used to support it. The base of the machine should also have provisions for fixing its base.
shows these limits for fine aggregate and for one size of coarse aggregate. There are several reasons for specifying grading limits and nominal maximum aggregate size; they affect relative. 82.

Aggregate impact value The value of aggregate impact test W1W2100 The value of aggregate impact test should not be more than 45 by weight of aggregates used for concrete other than wearing surface An impact value 35 is permissible for the bituminous macadam Maximum permissible impact value for the water bound macadam is 40
Feb 10 2021 Another benefit in addition to calculating the strength value the test outcome known to provide an indirect indicator of the strength characteristics. Generally the aggregate impact value does not exceed 30 for the aggregate used in pavement wear. The 35 highest allowable value for bituminous macadam and 40 percent for water-bound macadam .

Maximum horizontal stress 143 MPa is at the center plane top and bottom Of course since the static model is linear there is no need to re-run the model unless you want pretty plots. The static maximum fiber stress SX of 26.0 MPa could be multiplied by the 5.48 vertical Impact Factor to find the dynamic maximum SX stress of 143 MPa.

Typical Values. Typical values for theoretical maximum specific gravity range from approximately 2.400 to 2.700 depending on the aggregate specific gravity and asphalt binder content. Unusually light or heavy aggregates may result in a value outside this typical range.
