This course will tell you about hot-mix asphalt often used for high-performance pavements. The degree of performance required should be selected based on traffic conditions and the availability of satisfactory materials. Hot-mix asphalt mixtures consist of mineral aggregate and asphalt cement. These hot-mix asphalt mixtures are particularly suitable for airfield pavements, roads and streets, and storage areas. Course Outline 1. GENERAL 2. EQUIPMENT 3. MATERIALS 4. DENSE-GRADED HOT-MIX ASPHALT 5. POROUS FRICTION COURSE 6. STONE MATRIX ASPHALT This course will give civil engineers and others an introduction to the hydrological and hydraulic design of area drainage plans, including hydraulic structures, erosion control and riprap design.
