Abstract:

A plow-resistant recessed reflective marker (RRM) delineation system having a linear tapered profile and which uses a reflector base/reflector unit is proposed. A single-operator mechanized vehicle to install the RRM delineation system is described. This vehicle satisfies the design criteria which are given in the report. The apparatus automatically cuts the longitudinal main groove and the transverse drainage groove, cuts the reflective marker recess, removes the cutting debris from the groove, dispenses the adhesive for securing the marker to the pavement, installs the reflective marker unit, and propels the vehicle between adjacent markers. Details of the mechanical, hydraulic, pneumatic I and electrical subsystems are designed and presented. It is recommended that I this vehicle be built in order (1) to demonstrate the feasibility of the mechanized installation of the RRM delineation system and (2) to obtain generally lacking data on pavement cutting parameters.
