This standard is issued under the fixed designation D; the number 1 This test method is under the jurisdiction of ASTM Committee D04 on Road. The design procedures for Superpave and stone-matrix asphalt mixtures emphasize the importance of aggregate shape. The current test.

In some applications, reference radiographs for steel castings may not be entirely applicable to ductile cast iron material dependent upon design or other usage criteria.

Flat and Elongated Particles Overview The flat and elongated particle test is used to determine the dimensional ratios for aggregate particles of specific sieve sizes.

This characterization is used in the Superpave specification to identify aggregate that may have a tendency to impede compaction or have difficulty meeting VMA specifications due to aggregate degradation.

Flat or elongated particles Figure 1 tend to lock up more readily rather than reorient during compaction making compaction more difficult. They also have a tendency to fracture during compaction along their weak, narrow dimension, which can effectively make aggregate gradation finer and possibly cause lower-than-expected VMA.

Figure 1: Flat particles left and elongated particles right. This flat and elongated particle test uses a proportional caliper Figure 2 to help measure dimensional ratios. The specified ratio is set on the caliper and then about particles are tested for each specified sieve size.

Figure 2: Calipers for the flat and elongated particle test. The standard flat and elongated particles in coarse aggregate test is: ASTM D Flat Particles, Elongated Particles, or Flat and Elongated Particles in Coarse Aggregates Background Flat or elongated aggregate particles can, if present in sufficient number, 1 impede compaction or 2 affect HMA behavior by fracturing during compaction.

Compaction Difficulties As compared to cubic shaped particles ones with relatively equal diminsions in all directions flat or elongated particles tend to impede compaction. These particles tend to lock up with adjacent aggregate particles more readily than cubic particles and resist reorientation into a more dense configuration.

Therefore, significant numbers of flat or elongated particles can increase the compactive effort required to achieve a given density for a given HMA mixture.

In other words, flat and elongated particles make HMA compaction more difficult. Effect on HMA Behavior Flat or elongated particles also have a tendancy to fracture along their weak, narrow dimension when subjected to compaction loading. If they are present in large enough quantity, this fracturing can effectively change the aggregate gradation as larger flat and elongated particles are broken into smaller, more cubic particles Figure 3.

The resulting greater number of fine particles will fill existing void spaces and reduce the VMA.

This reduction in VMA can result in too little room available for the asphalt binder to coat the aggregate particles, which can result in mixture instability rutting and shoving. Also, the resulting lower VMA may make the HMA mixture highly sensitive to small variations in asphalt binder content.

Thus, a small increase in asphalt binder content associated with typical manufacturing tolerances that would normally be absorbed in an HMA with adequate VMA, may result in low stability in a low VMA mixture. Radha is moved by his devotion and Krishna grants his wish by making him blind again thus giving him everlasting fame. Countless such deeds figure in the Vedas and the Puranas, hearing which Suradasa humbly bows before that Lord.

Surdas is considered to be the foremost among them. By continuing past this page, you agree to abide by surdss terms.

A Lyric by Surdas: It propagates the path of Grace of God rather than of merging in Him, which seems an extension of the belief of earlier saints like Kabir Das.

Surdas spent the last years of his life in Braj, the place of his birth and lived on surdas ke dohe donations, which he received in return of his bhajan singing and lecturing on religious topics, until he died in c.

She however goes near him but Surdas, recognizing the divine sounds, pulls her anklets. As his fame spread far and wide, the Mughal emperor Akbar became his patron. Shri Vallabhacharya taught Surdas lessons in Hindu philosophy and meditation and put him in the surdas ke dohe of spirituality.

Radha asks Krishna why he helped Surdas for which Krishna says its surdas ke dohe his surdas ke dohe. Influence On Bhakti movement The philosophy of Surdas is a reflection doeh the times.It is not a complete procedure and should not be used to perform the test.
