2. Dowel bar retrofit - Wikipedia

   en.wikipedia.org/wiki/Dowel_bar_retrofit

   The caulking filler is used to prevent backfill material from flowing into the joint or crack. Non-shrink concrete backfill material that is tested as rapid set concrete patching materials is recommended for use on DBR projects. First, make two saw cuts in the pavement to outline the longitudinal sides of each dowel bar slot.

3. Concrete pavement restoration - Wikipedia

   en.wikipedia.org/wiki/Concrete_Pavement_Restoration

   Dowel bar retrofit (DBR) is a process that re-establishes load transfer capability on joints and cracks by installing epoxy-coated, round steel dowels into existing concrete pavement across transverse joints and/or cracks. Slots are cut using diamond-tipped saw blades; the existing concrete is removed and the dowels are placed in the slots ...

4. Self-healing concrete - Wikipedia

   en.wikipedia.org/wiki/Self-healing_concrete

   Autogenous self-healing crack. Self-healing concrete is characterized as the capability of concrete to fix its cracks on its own autogenously or autonomously. 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.

5. Concrete degradation - Wikipedia

   en.wikipedia.org/wiki/Concrete_degradation

   The filling of cracks, fissures or voids in concrete for structural purposes (restoration of strength and load-bearing capability), or non-structural reasons (flexible repairs where further movement is expected, or alternately to resist water and gas permeation) typically involves the injection of low viscosity resins or grouts based on epoxy ...

6. Filler (materials) - Wikipedia

   en.wikipedia.org/wiki/Filler_(materials)

   Filler can have a negative or positive effect on fatigue resistance depending on the filler type and shape. In general fillers create small discontinuities in the matrix. This can contribute to crack initiation point. If the filler is brittle fatigue resistance will be low, whereas if the filler is very ductile the composite will be fatigue ...

7. Self-healing material - Wikipedia

   en.wikipedia.org/wiki/Self-healing_material

   Upon cracking, these particles are exposed to oxygen, and in the presence of heat, they react to form new materials which fill the crack gap under volume expansion. [123] This concept has been proven using SiC to heal cracks in an Alumina matrix, [ 124 ] and further studies have investigated the high temperature strength, [ 125 ] and the static ...
