Rigid pavement is the technical term for any road surface made of concrete. Concrete roads are called rigid while asphalt -covered roads are flexible. These terms refer to the amount of deformation created in the road surface itself when in use and over time. The largest advantages to using concrete pavement are in its durability and ability to ...

pavements/structures include different joint patterns, different types of rigid pavement (e.g., CRCP/JPCP), structure foundations, drainage inlets, drainage inlet depressions, manholes and manhole frame and cover. Isolation joints keep cracks from propagating through the joint and are sealed to prevent water/dirt infiltration.

These are cracks in a flexible pavement overlay of a rigid pavement (i.e., asphalt over concrete). They occur directly over the underlying rigid pavement joints. Joint reflection cracking does not include reflection cracks that occur away from an underlying joint or …

Raveling The dislodgement of aggregate particles will result in the disintegration of the hot mixed asphalt progressively from the surface to downward direction.

Description. Series of closely spaced, crescent-shaped cracks near a joint, corner or crack. It is caused by freeze-thaw expansion of the large aggregate within the PCC slab. Durability cracking is a general PCC distress and is not unique to pavement PCC. Figure 1: D cracking at a slab.

Revised April 2007 Chapter 7 Pavement Maintenance Rigid Pavements Rigid pavements are normally composed of portland cement concrete (PCC) as the prime structural element. Depending upon conditions, the pavement slab may be designed with plain, lightly reinforced, continuously reinforced, pre-stressed, or fibrous concrete.

Deficiency of pavement materials: The various defects of rigid pavements are due to poor workmanship, use of soft aggregates, poor surface finish, improper curing poor quality of joint filler, etc. Structural inadequacy: If the pavement system is structurally unstable such as inadequate pavement thickness, inadequate subgrade support, poor subgrade soil, incorrect spacing of joints, etc., the ...

Full depth repair involves a full-depth slab removal followed by cast-in-place replacement of full lane-width areas of an existing rigid pavement. Typically the minimum length requirement is 6 ft (1.8 m); however, when repair areas are closely located, it is more cost effective to substitute a larger area, up

This design period is dependent on the nature and level of maintenance schedule. The design life may be taken as 10 to 20 years for low-traffic volumes (flexible pavements) and 20 to 30 years for high-traffic volumes, (rigid pavement) depending on the designer's discretion [IRC37-2001 and IRC58-2002]. 2.

Overview. The Rigid Pavement and Pavement Research Unit provides assistance, and technical expertise, in the areas of rigid pavement evaluation, rehabilitation, and construction. This Unit also coordinates all the activities associated with the Accelerated Pavement Testing Program and pavement research programs.

The Department will measure the quantity of full-depth pavement removal and rigid replacement by the number of square yards (square meters) repaired in the completed and accepted work. Full-depth pavement sawing is measured by the number of feet (meters) of perimeter full-depth saw cuts made in the completed and accepted work.

In this pavement, the load is distributed by the slab action, and the pavement acts as an elastic plate. Rigid pavements are constructed by using Portland cement concrete (PCC). The pavement materials are placed either directly on the prepared sub-grade or on a single layer of granular or stabilized surface.

Rigid Pavement Failures Spalling at the Joint:- Cracking, breaking or chipping of joint/crack edges or it is the breakdown of the slab near edge of the joint. Usually occurs within about 0.6 m (2 ft.) of joint/crack edge. Loose debris on the pavement, roughness, generally an indicator of advanced joint/crack deterioration. Excessive stresses at ...

Pavement Surface Repair, the researchers conducted a massive literature review and a nationwide survey of highway agencies to identify potentially cost-effective repair and treatment options. The information and findings from this study were then used in the subsequent field experiments

Rigid pavements can serve up to its design service life and even beyond if timely repairs are undertaken. All types of pavements deteriorate with time. Rate of deterioration is comparatively much slower than flexible pavements. The following figure indicates the typical treatment which may be considered with the age of Pavement.

Possible Causes: Movement of the rigid pavement slab beneath the HMA surface because of thermal and moisture changes. Generally not a load is initiated, however loading can hasten deterioration. Repair: Strategies depend upon the severity and extent of the cracking: Low severity cracks (< 1/2 inch wide and infrequent cracks).

Problem. Loose debris on the pavement, roughness, generally an indicator of advanced joint/crack deterioration. Possible Causes. Possible causes are (AASHTO, 1993 [1]):. Excessive stresses at the joint/crack caused by infiltration of incompressible materials and …

• Use partial-depth repair instead of FDR for spalls limited to the top one-third of the slab. • Full depth repairs should be used for rigid pavements with deterioration limited to isolated slabs, not widespread over the entire project length. • Structurally deficient pavements may require a …
