The aggregate crushing value (ACV) provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two versions available: 150 (standard) and 75 mm dia. The apparatus comprehend cylinder, plunger, base plate, tamping rod and measure.

Aggregate crushing Value (percent)=w2/w1*100 26.43 Aggregate crushing value = W2/W1 * 100 = 771/2917 * 100 = 26.43% RECOMMENDED VALUES The suitability of aggregate is adjudged, depending on its proposed use inthe pavement layers. Specified limits of percent aggregate crushing value for different types of road construction s given bellow.

Feb 03, 2012· From the experiment, we get average percent wear are 22.34% still not exceeding JKR's standard, <30%. So we can conclude that the aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.

In road construction, the quality of aggregates is assessed by the crushing strength of aggregates.For higher quality of roads, the aggregate should possess low aggregate crushing value. Here I am going to teach you how to determine the crushing strength of aggregates.First, let us check what are the various apparatus needed for this experiment.

Overview. The Los Angeles (L.A.) abrasion test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA.. Figure 1: L.A. abrasion testing equipment.

The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS-2386 Part-4. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be preferred.

Feb 04, 2012· The Polished Stone Value (BS 812: Part 3) Gives A Measure Of Resistance Of Road Stone To The Polishing Action Of The Pneumatic Tire. Under Conditions Similar To Those Occurring On The Surface Of The Road Where The Surface Of The Road Consists Largely Of Road Stone, The State Of Polish Of The Sample Will Be One Of The Major Factors Affecting The Resistance Of The Surface …

Experiment to Determine the aggregate impact value of different coarse aggregate ... Aggregate Impact Values and Aggregate Crushing Values are often numerically ... Observations & Results: ... to a sudden shock or impact which in some aggregates differs from its resistance to a slow compressive load.

The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. 2. Aggregate crushing value < 45% for aggregates used for concrete for non-wearing surfaces and <25% for wearing surfaces like …

The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load. The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is suspected.

number. Report the mean as the Aggregate Crushing Value, unless the individual results differ by more than 0.07 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number and report the median as the Aggregate Crushing Value.

METHOD B1 THE DETERMINATION OF THE AGGREGATE CRUSHING VALUE 1 SCOPE The ACV of an aggregate as defined hereunder is determined by crushing a prepared confined aggregate sample under a specified, gradually applied compressive load and

Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) Scope & significance: Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.

Apr 10, 2012· Aggregates used in the construction, should be strong enough to resist crushing. If the aggregates are weak, the stability of the structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied compressive…
