Quasco Case Studies

Case Study 1
Shanghai’s Experience on Utilizing the Rubblization for Jointed Concrete Pavement Rehabilitation

As agencies continue looking for cost-effective methods to rehabilitate deteriorated JCP, rubblization using resonant breaker has been experimented by the Shanghai Municipal Roadway Authority (SMRA). It was demonstrated that rubblization using resonant breaker offers a viable option for the SMRA because the rubblized pavement sections have been performing very well with no visible distress.

Case Study 2
Research on Resonant Rubblized Effects of PCC Pavement

In order to understand the rubblized effects of resonant rubblized PCC pavement, and obtain the design considerations and parameters, authors carried out this research based on Huqingping and Jinshan Roads in Shanghai. Read more.

Case Study 3
Concrete Pavement Rehabilitation Using Resonant Rubblization Technology 

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.

Case Study 4
Vibration Monitoring of Sonic Concrete Pavement Breaker

Saguaro GeoServices was to determine if vibrations from the sonic concrete breaking machine could potentially cause damage to the property at 815 W 18th St. SGS positioned monitoring equipment along the EB I-10 Frontage Rd, next to the property. The sonic concrete breaking machine was directed to the demolition area that was nearest to the property, about 125 ft from the monitor, and made two passes while under operation. Read more.
