Asphalt Paving Inspection (Part 2) - HD - By Civil Engineering Welcome To My Vietnam Civil Engineering ! like subscribe for more video https://www.youtube.com/channel/UCbP0_PnqWY9Z9DAdiWj1HDA?sub_confirmation=1 Asphalt concrete is one kind of composite material, which is one type of artificial stone received after shaping and dense. 1 mix ratio and logical components are kneaded thoroughly mixed materials including minerals, petroleum bitumen and additives, if any. Interstate highways (US) Differences with inorganic cement concrete [edit | edit source] Akashi-Kaikyo Bridge (Japan) Asphalt concrete with bitumen binder serves composite materials, concrete and cement serves mixed adhesive materials When first produced cement concrete quality control people who X / N right to the desired concrete Marx. And asphalt one focused on adjusting the mixture of mineral materials (crushed stone, grit, sand, mineral powder) Cement concrete construction designed for occasional loads change as the civil and industrial. Asphalt designed for load works continuously change (drag and compress the surface) as motorways and airports Asphalt concrete structures [edit | edit source] Asphalt concrete structure with two kinds of framed and unframed: Frame structure is the structure in which the pore filling factor between particles of sand and crushed stone frame with Asphalt binder is less than or equal to one. Thus, the binder Asphalt not easy motion, rubble and sand particles in contact with each other directly through the hard layer of bitumen to create the structure. The chassis can just rubble. In this case no movement rubble mixed with mortar (a mixture of sand, filler, bitumen). The presence of the space rigid frame increases the stability of the coating surface. Familiar frame structures generally contain from 4-14% mineral powder and bitumen from 5-7%. Frame structure is rubble and sand particles were shifted by excess of Asphalt binder (pore filling factor greater than 1). The intensity and cohesion of this structure reduces the heat-resistant surface coating made with plastic deformation. Optimal Structure of Asphalt Concrete dependent components of the material quality, production technology and choosing good ingredients mixed concrete.
