Rehabilitation of concrete pavements is a major issue within TxDOT. The department has many miles of old jointed and continuously reinforced concrete pavement which are approaching the end of their service life. Black topping and white topping can be used to gain additional life, but these treatments are often impacted by reflection cracking.

concrete overlays is one of several methods that have been used in an attempt to prevent, reduce the severity and/or delay the occurrance of reflective cracks. Design and construction guidelines and typical specifications for paving fabrics are presented in this report. These guidelines
concrete pavement construction technology. Although Item P-501 has been modified several times, many of the changes and new concepts have not been formally incorporated in the specification. As part of a recent IPRF study, a proposed specification for concrete airfield pavement has been developed for possible adoption by the FAA.

Dowel bar retrofit (DBR) consists of installing epoxy-coated, smooth, round dowel bars into existing concrete pavement across transverse joints and/or cracks. Slots are cut using diamond-tipped saw blades; the concrete is removed using lightweight jackhammers. The dowel assemblies are placed in the slots across the joints or crack and anchored into the existing pavement with non-shrink concrete …
(9) Place the fabric bond breaker layer to a grade and tolerance such that the overlying PCC pavement thickness will meet minimum design requirements. (10) Slightly dampen, but not saturate, the fabric, prior to concrete placement. (B) Maintenance . Maintain the geotextile fabric bond breaker layer during and after placement throughout its entire
A bond breaker should always be used between concrete pavement and cement treated base. There have been several instances across Texas where excessive cracking and premature failures occurred when a concrete slab was placed directly on cement treated base.
breaker, drainage and separation interlayer for portland cement concrete pavements in new construction and unbonded overlays. Example applications are, but not limited to, existing pavement with a new concrete pavement overlay, and between a chemically treated subbase or base and a new concrete pavement.

Case Study: Concrete Rubblization Interstate 86 Allegany County, NY. Concrete rubblization is a process in which existing concrete roadways are pulverized, in place, to create a flexible base for asphalt overlay. The process recycles existing pavement and reduces the possibility of reflective and joint cracking of the asphalt overlay.

Maintain the geotextile fabric bond breaker layer during and after placement throughout its entire length until placement of the concrete overlay. During this maintenance period, correct any
Apr 19, 2017 Remove concrete pavement between narrowly spaced sawcuts at the end of the slab with air hammers and hand tools to minimize spalling. Patches less than 100 feet in length will be removed without disturbing the subbase/subgrade according to subsection 603.03 of the Standard Specifications for Construction.

415.2.5 Concrete Pavement Gaps (1) Use concrete of the same mix design used for the contiguous pavement. If the engineer allows paving through the gap, use a concrete mix design that will develop 2500 psi opening strength in an engineer-approved maximum time. 415.2.6 Joint Filler
The Concrete Pavement Guide (CPG) provides a comprehensive overview of current new construction-reconstruction, preservation, and rehabilitation strategies used by the Department for concrete pavement. The information in this guide applies to all concrete pavement and composite pavement that was not previously cracked and seated.

Cracks that Occur Well After Sawing— Sometimes cracks continue to form as much as 60 days to 2 years after paving and sawing are complete. In some cases these may be cracks that formed early but were not visible. In other cases, uncontrolled cracking that first occurs or continues to develop well after paving and sawing is a clue that something is restraining or moving the concrete slabs to ...

Recycling concrete pavement into granular subbase was a time consuming process. First, the pavement was broken with a pavement breaker. Next, the rubblized pavement was hauled to a plant site, crushed and then hauled back to the project site. In 1993, Manatt’s Inc., Duit Construction and Wendling Quarries developed a concept to break,
