The correct answer is: A. sheet asphalt
Sheet asphalt is a type of asphalt pavement that is made up of a layer of asphalt concrete that is applied to a prepared base. It is a common type of pavement for roads and highways, and it can also be used for bridge deck slabs.
Sheet asphalt is a good choice for bridge deck slabs because it is a durable and water-resistant material. It is also relatively easy to install and maintain.
B. Bituminous carpet is a type of asphalt pavement that is made up of a layer of bitumen that is applied to a prepared base. It is a less common type of pavement than sheet asphalt, and it is not typically used for bridge deck slabs.
C. Mastic asphalt is a type of asphalt pavement that is made up of a mixture of asphalt cement, sand, and filler. It is a very dense and durable material, and it is often used for high-traffic areas. However, it is also a very expensive material, and it is not typically used for bridge deck slabs.
D. Rolled asphalt is a type of asphalt pavement that is made up of a layer of asphalt concrete that is rolled into place. It is a common type of pavement for roads and highways, but it is not typically used for bridge deck slabs.
Bridge deck slabs are the horizontal surfaces of bridges that support the weight of the bridge deck and the traffic that travels over it. They are typically made of concrete, but they can also be made of steel or wood.
The surfacing material for a bridge deck slab must be durable, water-resistant, and easy to maintain. It must also be able to withstand the weight of the bridge deck and the traffic that travels over it.
Sheet asphalt is a good choice for bridge deck slabs because it meets all of these requirements. It is a durable and water-resistant material, and it is relatively easy to install and maintain.
