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.

“…The existing versions of the AASHTO design guide are empirically based on performance equations developed using the 1950s AASHO Road Test data (AASHTO 1962). A nationwide survey conducted in 1999 on the use of rubblization indicated that the AASHTO (1993) is the most widely used design procedure by state DOTs in the USA (Ksaibati et al 1999). Thompson (1999) summarized the deficiencies associated with the AASHTObased procedures and proposed Mechanistic-Empirical (M-E) based design concepts and procedures for the analysis and design of HMA overlay thickness for rubblized PCC pavements.…”

“…The results from a comprehensive investigation conducted by PCS/Law (PCS/Law 1991), the National Asphalt Pavement Association (NAPA) study (NAPA 1994), and a nationwide survey conducted by the Florida Department of Transportation (DOT) (Ksaibati et al 1999) all indicate that rubblization is the most utilized procedure for addressing reflection cracking (Heckel 2002). Rubblization involves breaking the existing PCC slab into pieces and overlaying it with HMA.…”

In Iowa, there are many portland cement concrete (PCC) type highway pavements. These pavements deteriorate over time due to materials, traffic and environmental related distresses and they are commonly rehabilitated by providing a hot-mix asphalt (HMA) overlay. To mitigate reflection cracking, a frequently observed distress on HMA overlaid PCC pavements, various fractured slab techniques are used, of which rubblization is considered to be the most utilized and effective technique. This paper describes the development of a mechanistic-empirical (M-E) thickness design system for HMA overlaid rubblized PCC pavements. In this computerized design procedure, HMA fatigue and subgrade rutting failure are considered using appropriate transfer functions. The design system strain predictions were validated using field results from an instrumented trial section in Polk county, Iowa.

Resonance drilling is a new technology, still at the laboratory stage. It has great potential to state mechanical vibration excited by harmonic vibration in rocks and an apparatus was built to achieve other parameters on the rate of penetration (ROP) in resonance drilling was analyzed. The results show that the rock drillability decreased with an increase in excitation frequency. When drilling with a large size drill bit, the ROP increased with excitation frequency. The ROP reached a maximum value at the resonant frequency of the rock. The ROP of the bit increased linearly with rotary speed when no vibration was applied on the rock and increased approximately exponentially when harmonic vibration was applied. In addition, the resonant frequency of the rock was changing during the process of rock fragmentation, so in order to achieve the desired resonance of the rock, it is necessary to determine an appropriate harmonic vibration excitation frequency.
