2. Concrete pavement restoration - Wikipedia

   en.wikipedia.org/wiki/Concrete_Pavement_Restoration

   When installing pavers over top of an existing asphalt of concrete pad, there are three installation options: sand set, bituminous set, and mortar set. [1] Due to rising oil prices, these methods are often less expensive than an asphalt overlay and last three times longer in addition to providing a greener, more sustainable solution. [2] [3] [4]

   The repair needed also differs based on the severity and extent of the cracking. For minor cracks, preventative crack filling is a good procedure that can help prevent future potholes from forming. In the early stages, sealing cracks with crack sealant limits further deterioration of the subgrade due to moisture penetration.

4. Reflective crack - Wikipedia

   en.wikipedia.org/wiki/Reflective_crack

   Cracks under the overlay can cause stress concentration at the bottom of the overlay. Due to the repeated stress concentration, a crack starts in the overlay that has a similar shape to the crack in the old pavement. This crack is called a "reflective crack". [1] Reflective cracking can be categorized as one of the distresses in asphalt ...

5. Pavement cracking - Wikipedia

   en.wikipedia.org/wiki/Pavement_cracking

   Different types of pavements develop different cracks. Type of cracking is also correlated with the type of climate and traffic. [ 1 ] [ 2 ] Sometimes the cracks are aggregated using an index such as Crack index , and sometimes they are merged with other distresses and are reported using Pavement Condition Index .

6. Self-healing concrete - Wikipedia

   en.wikipedia.org/wiki/Self-healing_concrete

   It not only seals the cracks but also partially or entirely recovers the mechanical properties of the structural elements. This kind of concrete is also known as self-repairing concrete. Because concrete has a poor tensile strength compared to other building materials, it often develops cracks in the surface. These cracks reduce the durability ...

   Asphalt batch mix plant A machine laying asphalt concrete, fed from a dump truck. Asphalt concrete (commonly called asphalt, [1] blacktop, or pavement in North America, and tarmac or bitumen macadam in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams.
