Abstract:
Substantial resources are required to preserve aging highway systems. Various alternatives have been used for the rehabilitation of concrete pavements, including bonded and unbonded overlays, full-depth repair, crack and seat and asphalt overlay, joint and crack repairs, asphalt overlay, and rubblization with asphalt surface overlay. Presented are the results of extensive field investigation of rubblized concrete pavements. Various trenches were made in the rubblized pavements before the asphalt surface was placed. Some trenches were made at midslab, and others were made at old joints and cracks. In some trenches, permeability tests were conducted. Advantages and shortcomings of the rubblization procedures are presented and discussed. It is shown that well-executed rubblization procedures lead to durable pavements and that, for certain concrete pavements, rubblization is not a viable option because it may lead to inadequate pavement performance.

Abstract:
Reflective cracking is a common type of pavement distress, which manifests as cracks in an underlying layer propagating through to the surface of a pavement structure. To minimize reflective cracking of asphalt layers in composite pavements, four treatments are commonly used: standard/full rubblization, modified rubblization, crack and seat, and rock interlayer. The four types of treatment were evaluated to determine their effectiveness in mitigating reflective cracking via non-destructive Falling Weight Deflectometer tests and Surface Wave Method tests to measure layer modulus, along with field pavement performance surveys. It is found that moduli measurements from Surface Wave Method tests have reduced uncertainty comparing to those from Falling Weight Deflectometer tests, (2) the moduli of thin rock interlayers were captured by Surface Wave Method, but missed by Falling Weight Deflectometer. In addition, the Surface Wave Method results show that (1) crack and seat treatments provide the highest moduli, followed by modified rubblization, and (2) standard rubblization and rock interlayers provide moduli that are slightly lower than the other two treatments. Pavement performance survey was also conducted concurrently with the in-situ modulus tests. Based on the results of this study, modified rubblization and rock interlayer treatments are recommended for mitigation of reflective cracking.

Abstract:
Reflective cracking distresses frequently occur on the hot mix asphalt (HMA) overlay due to the movements of the underlying Portland cement concrete (PCC). Rubblization was proven in North America to be an effective approach among slab fracturing technologies for solving the premature reflective cracking problem. This paper presents the procedure of applying the rubblization technology in HMA overlay design in a research effort in China to develop the Chinese standard. In the study, the validity of rubblization was analyzed by a trench survey and sieve tests; the layer moduli of the composite subgrade and rubblized concrete slab were determined using FWD and plate bearing tests and a conversion chart; the thickness design for the HMA overlay over the rubblized PCC pavement was conducted using a Chinese version mechanistic–empirical design process; and finally the in-service monitoring over the pavements built using the developed procedure was conducted to test the validity of the procedure.

Abstract:
Several in‐place rehabilitation techniques have been used before placing an Asphalt Concrete (AC) overlay on Portland Cement Concrete (PCC) pavements in attempts to minimize reflection cracking. Among these techniques, “rubblization” of PCC has been recognized to be the most utilized procedure for the mitigation of reflection cracking in US. This paper presents the practices on the use of rubblization in US and discusses the performance of this technique based on field evaluation. The specifications for the rubblization procedure used by state Department of Transportation (DOT) in US were reviewed. To evaluate the performance of rubblization technique, the structural and the surface conditions of AC overlaid pavements with rubblized PCC layer are compared to those with virgin PCC layer. A series of field experiment tests were carried out on six representative AC overlaid pavements with both rubblized PCC and virgin PCC in Iowa during 2007. The field experiment tests include the Nondestructive (NDT) and destructive tests, and the distress survey. Deflection Basin Parameters (DBPs) were derived from NDT test results to characterize the structural condition of pavements. The results indicate that the rubblized PCC layer has strength comparable to that of virgin PCC layer and has better performance under that structural condition.

Natūriniai eksperimentiniai bandymai buvo atlikti, taikant neardomuosius (NDT) ir ardomuosius tyrimu metodus. Ilinkiai (DBPs) buvo nustatyti NDT bandymo metodais, charakterizuojančiais konstrukcines dangu salygas. Darbo rezultatai parode, kad pagal naujaji metoda paruoštas PPC sluoksnis igijo panašu stipri kaip ir PCC sluoksnis su standartine danga, tačiau regeneruota PPC danga igijo geresniu eksploataciniu charakteristiku.

Abstract:
In the process of old cement concrete pavement is transformed, asphalt overlay is the common method. However, due to the cracks of the original cement concrete slab when load and temperature and humidity changes will produce a relative displacement, it can not avoid reflective cracking. So in order to prevent the reflective cracking of asphalt overlay, crush the old cement concrete pavement is the important manner. Different construction technology is divided into three kinds: cracked steady pressure, impact compaction and rubblization technology. Among these, rubblization is an important technology that utilizes in-situ crushing technique in cement concrete pavement. This article discusses the characteristics of these three techniques, and it also evaluates effectiveness.

Abstract:
With a long history of constructing jointed concrete pavements, Pennsylvania pursued the construction of Special Pavement Studies (SPS-6) sections for the rehabilitation of jointed concrete pavements experiment. After 10 years of service under very high loads on rural Interstate highways, a number of sections required renewal. The performances of the eight standard Strategic Highway Research Program sections, a control section, and three state supplemental sections were examined. The experiment included a broad range of treatments, including minimum and maximum concrete pavement restoration, the use of thin and thick overlays, and the use of crack or break and seat as well as rubblization as pretreatments for pavement overlays. Ten years after construction, many of the pavements that received the treatments are in need of major rehabilitation. This provides an opportune time to evaluate both the structural and functional performances of these test sections to date. Additionally, an evaluation of cost-effectiveness showed the importance of performing thorough evaluations of projects for rehabilitation and the potential benefit of rubblization of badly damaged jointed concrete pavements, a method used on the state supplemental sections, as a preoverlay strategy.

Abstract:
Void is a major disease of cement concrete pavement, and it is also the inducement of other diseases. In order to predict the void, this paper quantificational analyzes the relationship between the times of load function and the lost of materials caused by erosion based on the analysis of the shape and height of void. And then it puts forward that the volume of the lost of materials caused by erosion is equal to the void under slab and gets the prediction models of voids beneath slab corner and along longitudinal joint edge. The results suggest that when the void height is less than side length, the prediction model of void beneath slab corner is same to the along longitudinal joint edge. The development of the void only has relationships with the anti-scour performance of the base course material, the ratio of height and size of void, and the times of standard axle load.

Abstract:
One of the Indiana Department of Transportation's (INDOT's) strategic goals is to improve its pavement design procedures. This goal can be accomplished by fully implementing the 2002 mechanistic–empirical (M-E) pavement design guide (M-E PDG) once it is approved by AASHTO. The release of the M-E PDG software has provided a unique opportunity for INDOT engineers to evaluate, calibrate, and validate the new M-E design process. A continuously reinforced concrete pavement on I-65 was rubblized and overlaid with a 13–in.-thick hot-mix asphalt overlay in 1994. The availability of the structural design, material properties, and climatic and traffic conditions, in addition to the availability of performance data, provided a unique opportunity for comparing the predicted performance of this section using the M-E procedure with the in situ performance; calibration efforts were conducted subsequently. The 1993 design of this pavement section was compared with the 2002 M-E design, and performance was predicted with the same design inputs. In addition, design levels and inputs were varied to achieve the following: ( a) assess the functionality of the M-E PDG software and the feasibility of applying M-E design concepts for structural pavement design of Indiana roadways, ( b) determine the sensitivity of the design parameters and the input levels most critical to the M-E PDG predicted distresses and their impact on the implementation strategy that would be recommended to INDOT, and ( c) evaluate the rubblization technique that was implemented on the I-65 pavement section.

Abstract:
Hot mix asphalt (HMA) overlays on fractured Portland cement concrete (PCC) is a common rehabilitation alternative used for PCC pavements in Pennsylvania. Several fracture techniques including rubblization, crack and seat (C&S), and break and seat (B&S) have been used for decades to minimize reflective cracking by reducing the effective slab length and, with it, expansion/contraction movement. The design of this type of overlay requires knowledge of the structural capacity of the fractured PCC layer. The AASHTO 93 and Pavement ME design methods are used by the Pennsylvania Department of Transportation (DOT). These methods and the Pennsylvania DOT documentation recommend certain values to characterize the structural capacity of the fractured PCC. However, the guidance envisaged the selection of these values provided by these design methods and the Pennsylvania DOT documentation is limited. The objective of this study is to determine realistic Pennsylvania-specific elastic modulus (EPCC) values and layer coefficients (LC) to characterize the in situ behavior of fractured PCC layer for jointed reinforced concrete pavements (JRCP) and jointed plain concrete pavements (JPCP). To obtain these structural properties, 11 different rehabilitation projects located in Pennsylvania were analyzed using falling weight deflectometer (FWD) data, backcalculation programs, and statistical methods. Based on this analysis, the recommended values of EPCC and LC for C&S overlay design are 360 ksi (kips per square inch) and 0.32, respectively. In the case of B&S overlay design, these values correspond to 400 ksi and 0.34, respectively. The variability of the slab fracturing process and the reduction of the structural capacity caused by fracturing were also analyzed in this investigation.
