Methods for determination of aggregate impact value (AIV ...
Materials Lab Methods for determination of aggregate impact value (AIV) (BS 812112: 1990) Prepared by: Eng. Mohammed Mousa The Islamic University of Gaza IUG. Scope: This Part of BS 812 describes methods for the determination of the aggregate impact value (AIV) which gives a relative measure of the resistance of an aggregate to sudden shock or impact. Two procedures are .
QUALITY ASSURANCE for AGGREGATES
The aggregate crushing value should not exceed 45% for aggregate used for concrete other than for wearing surfaces, and 30 % for concrete for wearing surfaces, such as runways, roads for pavements. Aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, As an alternative to crushing value, the aggregate impact value should not exceed 45% by ...
Pavement materials: Aggregates
Extracted rock is typically reduced to usable sizes by mechanical crushing. Manufactured aggregate is often a bye product of other manufacturing industries. The requirements of the aggregates in pavement are also discussed in this chapter. Desirable properties Strength The aggregates used in top layers are subjected to (i) Stress action due to traffic wheel load, (ii) Wear and tear, (iii ...

Inspection Sampling Procedures for Fine Coarse Aggregates
The lab should be set up to meet the flow requirements of the most routine test performed. The need for backtracking should be minimized, especially if more than one technician is working at a time. A little extra time and thought to the set up of the lab will significantly increase productivity and decrease turnaround time. 2 Sampling Sampling Techniques Safety Sample References Size of ...
AGGREGATE TOUGHNESS/ ABRASION RESISTANCE AND DURABILITY ...
Bullas and West [4] reported the aggregate impact value did not, but the aggregate crushing value did separate suitable and unsuitable aggregate for bitumen macadam roadbase. Fookes, Gourley and Ohikere [5] recommended that combinations of physical tests such as impact, crushing and abrasion resistance be used to assess aggregate durability.

Aggregate Crushing Value | seperti layang layang
· Aggregate Crushing Value. Introduction. The principal mechanical properties required in stones are satisfactory resistance to crushing under the roller during construction and adequate resistance to surface abrasion under traffic. Aggregates used in road construction, should be strong enough to resist crushing under traffic wheel loads.
