What causes longitudinal cracking in concrete?

The field investigations conducted in Texas, USA, identified several causes leading to irregular longitudinal cracking in several concrete pavements, (1) late or shallow saw cutting of longitudinal saw-cut joints, (2) inadequate base support under the concrete slab, (3) high level of built-in warping and curling, (4) …

What causes longitudinal edge cracking?

Transverse/Longitudinal Cracking Longitudinal cracks are caused by a poorly constructed paving lane joint, temperature cycling, reflective cracking in a base layer, or volume changes in subgrade.

What is longitudinal crack?

Longitudinal cracking is cracking in the surface of road that runs longitudinally along the pavement. It can consist of a single crack or as a series of parallel cracks.

What is the difference between repair and rehabilitation?

Repair is the process of restoring something that is damaged or deteriorated or broken, to good condition. 3. Define Rehabilitation. Rehabilitation is the process of returning a building or an area to its previous good conditions.

What is civil repair?

Define Repair. Repair is the technical aspects of rehabilitation. It refers to the modification of a structure, partly or wholly, which is damaged in appearance or serviceability.

Which of the following is simplest method of crack repair?

Routing and sealing is the simplest and most common concrete crack repair method. The idea here is to treat the crack like a joint. The technique simply involves enlarging the cracks on the surface and then sealing them with a joint sealant.
