PCC overlays of existing rigid pavements have been used for years to restore pavement structural capacity. All types of rigid pavement designs (JPCP, JRCP, CRCP) are appropriate to be overlaid and to be used as overlays.This section briefly describes the AASHTO design procedure for the two major types of PCC overlays: unbonded and bonded.. Unbonded. An unbonded PCC overlay consists of a ...

However, continuing advancements in recycling technologies, including hot in-place recycling (HIR), cold in-place recycling (CIR), cold central plant recycling (CCPR), and fulldepth reclamation (FDR), and their successful implementation and growing positive performance record, are providing pavement managers with a wider variety of technically acceptable, cost effective reuse and recycling ...
Concrete pavement can be maintained over time utilizing a series of methods known as concrete pavement restoration which include diamond grinding, dowel bar retrofits, joint and crack sealing, cross-stitching, etc. Diamond grinding is also useful in reducing noise and restoring skid resistance in older concrete pavement.

pavement distress at joints and intermediate cracks be-tween joints. Continuously reinforced pavements are built without contraction joints, Due to the relatively heavy, continu-ous-steel reinforcement in the longitudinal direction, these pavements develop transverse cracks at close inter-vals. A high degree of load transfer is developed at these

Rigid pavements are so named because the pavement structure deflects very little under loading due to the high modulus of elasticity of their surface course.A rigid pavement structure is typically composed of a PCC surface course built on top of either (1) the subgrade or (2) an underlying base course.Because of its relative rigidity, the pavement structure distributes loads over a wide area ...
