Automated Shotcrete Machine for Road Maintenance

The numerous advantages of the shotcrete process are especially evident when viewed from a sustainability point of view. Unlike many sustainability claims that are based on political or social ideals that are often difficult to quantify and substantiate, the sustainability advantages of the shotcrete process directly and positively impact the economic side of a project, falling in line with traditional business decisions such as material, labor, and time savings as well as improved quality.

In addition to the following “top ten” sustainability advantages of shotcrete, ASA’sSustainability page offers a wealth of information on the topic.

•Formwork savings of 50 to 100% over conventional cast-in-place construction;

•Formwork does not have to be designed for internal pressures;

•Complex shapes require very little, if any, formwork;

•Crane and other equipment savings or elimination;

•Labor savings of at least 50% in repair applications;

•New construction speed savings of 33 to 50%;

•Speed of repair reduces or eliminates downtime;

•Better bonding to the substrate, which enhances durability;

•Adaptability to repair surfaces that are not cost-effective with other processes; and

•Ability to access restricted space and difficult-to-reach areas, including overhead and underground.
