for mass concrete such as dams etc. and 63mm for plain concrete. Crushed hard stone and gravel is the common materials used as coarse aggregates for structural concretes. Coarse aggregates usually obtained by crashing granite, gneiss, crystalline lime stone and good variety of sandstone etc.

ACI AsphAlt & CONCRETE, INC. 763.424.9191 info@aciasphalt | Guide to Asphalt Maintenance v1.1 4 There are a number of different rating systems used by contractors and engineering companies to determine the condition of an asphalt pavement. These systems generally rate your pavement on a 1–10 scale (or similar measurement

The anti-fatigue properties of asphalt concrete substructure were evaluated by the four-point bending fatigue test. The test temperature was 15 °C, the loading frequency was 10 Hz, and the test was controlled by constant strain. The test specimen was a 380 mm × 50 mm × 63.5 mm prism.
