Modular Building Block Approach to Construction Assembly in Place Mini-Roundabouts

ZKxKZ with partners at UMass-Lowell Plastics Engineering Department and Voltek will develop low cost mini-roundabout technology based on a rapidly installable system of interlocking modules made from recycled plastic materials. Phase I will focus on material and process selection, along with modul configuration optimization, governed by design for low acquisition, installation and life cycle cost. Implication for automated manufacturing, along with maximization of performance (particularly truck axle loading), will play an important part in all design decisions. Phase I will include use of accelerated testing techniques to simulate to the greatest extent possible the ability of the modular system to perform well when subjected to axle loads and snow plow impact. It is expected that the resulting system will reduce cost and shorten installation time of mini-roundabouts, leading to their more widespread use, with associated improvements tc traffic flow and safety. Study of the potential application of an optional composite post, developed by the PI for a separate application, will be included in Phase I. This post yields when impacted then self-rights to vertical after the impact, adding to improved safety and lower maintenance cost.
