Cracking along the road axis possibly due to poor construction and formation of a cold joint. Pavement crack refers to a variety of types of pavement distresses that occur on the surface of pavements. Different types of pavements develop different cracks. Type of cracking is also correlated with the type of climate and traffic.
WebHorst (geology) In physical geography and geology, a horst is a raised fault block bounded by normal faults. [1] Horsts are typically found together with grabens. While a horst lifted or remains stationary, the grabens on either side subside. [2] This is often caused by extensional forces pulling apart the crust.
