According to wikipedia, A road is a thoroughfare, route, or way on land between two places that has been paved or otherwise improved to allow travel by foot or some form of conveyance, including a motor vehicle, cart, bicycle, or horse.
Roads consist of one or two roadways (British English: carriageways), each with one or more lanes and any associated sidewalks (British English: pavement) and road verges. There is often a bike path. Other names for roads include parkways, avenues, freeways, tollways, interstates, highways, or primary, secondary, and tertiary local roads.
Prefabrication of any structure component off-site during highway construction (or reconstruction) offers major time and user cost savingsin comparison with the traditional cast-inplace methods of construction. Precast prestressed road pavements’ technology offers dramatic increase in durability, while it also substantially decreases the construction time and the user costs. The choise of material for molding concrete road paving blocks greatly influences the end product. be it a road kerb, paving block or side slab. kafum engineering understand this best and therefore ensure that all road construction molding equepments are made to pass the highest standerd.
A concrete slab is a common structural element of modern buildings. Horizontal slabs of steel
reinforced concrete, typically between 4 and 20 inches (100 and 500 millimeters) thick, are most
often used to construct floors and ceilings, while thinner slabs are also used for exterior paving.
Sometimes these thinner slabs, ranging from 2 inches (51 mm) to 6 inches (150 mm) thick, are
called mud slabs, particularly when used under the main floor slabs or in crawl spaces.
Slabs can be on-ground, suspended, or a mix of both. They can be insulated, both underneath
and on the edges.
