Pages : 154
Book Description
This manual (FHWA-RD-99-152) presents guidelines and recommendations to assist highway maintenance agencies and other related organizations in planning, constructing, and monitoring the performance of concrete pavement partial-depth spall repair projects. Included in the manual are discussions pertaining to when partial-depth spall repair operations are appropriate, the types of repair materials and construction methods that should be used, how each individual step in a spall repair operation should be performed, and how the performance and cost-effectiveness of spall repairs can be evaluated. This report will be of interest and benefit to various levels of agency maintenance personnel, from crew supervisors to the chief maintenance engineer.

Book Description
The Strategic Highway Research Program's project H-106, the partial-depth spall-repair experiment, is the most extensive effort to date to evaluate the performance of various rapid-setting materials and procedures used in the repair of partial-depth spalls in Portland cement concrete pavements. Four test installations consisting of a total of 1,607 patches, were constructed in 4 climatic zones, and the experiment investigated the performance of several cementitious, polymeric, and bituminous patching materials, and procedures used in repairing jointed concrete pavements. The techniques included the following: saw and patch, chip and patch, mill and patch, waterblast and patch, and minimal praparation clean and patch under adverse conditions. The patch performance has been good: only 2.3% of the patches have failed.

Book Description
This publication includes two pavement maintenance manuals intended for use by highway maintenance agencies and contracted maintenance firms in the field and in the office. Each is a compendium of good practices for Portland cement concrete joint resealing and partial-depth spall repair, respectively, and stem from two Strategic Highway Research Program studies. The first manual covers the need for joint resealing, the planning and design, construction, and evaluation of joint seal performance. The second manual gives a description of procedures and materials recommended for partial-depth spall repair in jointed Portland cement concrete pavements. The manual covers the details of planning and design, construction, and evaluation of performance.

Book Description
"The Strategic Highway Research Program (SHRP) H-106 maintenance experiment and the Federal Highway Administration (FHWA) Long-Term Monitoring (LTM) of Pavement Maintenance Materials Test Sites project studied the repair of partialdepth spalls in concrete pavements. The purpose of partial-depth spall repair is to restore a pavement's structural integrity, improve its ride quality, and extend its serviceable life. Highway agencies spend a large amount of time and money annually performing partial-depth spall repairs, both as temporary and permanent fixes. Frequently, the repairs are not made as efficiently as desired or do not perform as long as intended. The primary consequences are added disruption to traffic, more exposure of patching crews to traffic, and additional maintenance expenditures. The purpose of this study, then, was to address the merits and deficiencies of current spall repair materials, designs, and practices. The study evaluated the relative performance of selected patching materials, as well as the effect of selected repair methods. The study also examined repair material properties and tests that correlate well with field performance. This report documents the entire portland cement concrete (PCC) partial-depth spall repair study, including the installation of 30 unique repair types (i.e., combinations of patching material and patching method) at 4 different test sites, the laboratory testing of experimental repair materials, and the 7-year performance monitoring of the various partial-depth repairs. It also discusses the results of comprehensive statistical analyses conducted on material performance and laboratory testing data. The results of a detailed cost-effectiveness analysis are also presented"--Technical report documentation page.

Partial-depth Repair of Jointed PCC Pavements

ISBN:
Category : Pavements, Concrete
Languages : en
Pages : 50
Book Description
The installation of durable patches on jointed portland cement concrete pavement using several types of cast-in-place concrete, is described. The recommended procedures for pavement preparation and patch installation are given, and additional maintenance procedures as cleaning and sealing joints and assuring proper drainage are briefly discussed. The successful evaluation of proprietary products for repair concretes through a laboratory determination of concrete properties, field use of acceptable products, and the assessment of performance data during and after installation is discussed. Included in this study were some of the cements, admixtures, and other special products for repair concretes, from a list maintained by the Materials Division of the Virginia Department of Highways & Transportation to provide assistance in the selection of the proprietary products. A production chart is presented as an aid in estimating the number of patches that can be installed during typical lane closure periods. Concretes with short curing times increased potential production, however, the selection of a repair product is acknowledged to also be dependent on factors such as cost and availability of materials. A procedure for installing precast patches for partial-depth repairs is described however; the rate of pavement preparation is too slow to make this procedure a viable alternative to cast-in-place patching.
