Results showed that the asphalt aggregate interface strength increased when the limestone surface texture features increased In addition as illustrated in the test results of #2 group the averaged ST value of limestone #2 was which was very close to the eigenvalue of #2 group granite of and averaged ST value of #2 group
Asphalt mixtures consisting of mineral aggregates bound with a bitumen binder [1] are used extensively as road surface asphalt is a relatively cheap material [1] the disruption to traffic flows and costs of replacing degraded road surfaces are significant leading to a demand for more durable is a major cause of such premature
Reclaimed asphalt pavement RAP is a recyclable aggregate produced during the demolition of old flexible pavements and consists of natural aggregates NA coated with aged bitumen The detrimental effect caused by the bitumen coating on strength and porosity has limited the use of RAP on traditional cementitious systems This study investigates the

soil times their volume Compare the mass of clay to that of the aggregate fraction of the concrete mixture to calculate the percentage of contamina tion ASTM C 33 aggregate specifications allow up to 3% contamination of fine aggregates sand with clay lumps and friable particles and 3 or 5% contamination of coarse aggregates with clay
The term sand equivalent expresses the concept that most fine aggregates are mixtures of desirable coarse particles sand and generally undesirable clay or plastic fines and dust ASTM 2003 [1] These materials can coat aggregate particles and prevent proper asphalt binder aggregate bonding
The strength and shape of aggregates significantly affect the durability performance tensile strength and stiffness of the asphalt pavements [7] [8] The aggregate must have the appropriate shape and strength for the high performance pavement because it directly influences the performance of the asphalt pavements [9] The excessive elongated and flaky
