Stabilized pavement bases, such as soil-cement and cement-treated bases, have provided economical, long-lasting pavement foundations for nearly 70 years. Many engineers and public works officials are turning to a process called full-depth reclamation (FDR) with cement for a quality stabilized pavement base.

Full depth repair is recommended in case a weak concrete is identified at the site of distress or the pavement have multiple type of distresses such as cracking, breaking of joint, locking of joint, etc. . Repair of full depth transverse cracks requires new dowel bars to be placed and one new joint to be constructed.
