Section XXIII-101 - General

A. Qualified products listings and the evaluation of materials for these lists are administered by the traffic services section and the materials section within the Department of Transportation and Development.

B. Qualified products listings are basically developed for those materials and items requiring source approval, performance evaluation, in-service evaluation, long term testing, or other conditions not conducive to normal sampling and testing of materials received at the point of delivery. Prospective sources of supply should be aware that those samples required for evaluation must be furnished at no cost to the department, and that results of tests and evaluations may be published and made available for public distribution by the department. Testing and evaluation time varies depending upon the specific item; some items require considerable time for testing and evaluation. The qualified products listings are in two general areas, i.e., traffic control devices and construction materials. Examples of such lists are as follows.

1. Traffic control devices:

a. conflict monitors;

b. controller cabinets;

c. coordination units;

d. disconnect hangers and leads;

e. flashers for controllers;

f. flashing switches for beacons;

g. load cells;

h. loop amplifiers;

i. pedestal bases;

j. pre-emption units;

k. pull boxes;

l. signal lenses;

m. signal and pedestrian heads; and

n. traffic signal controllers.

j. elastomeric railroad grade crossings;

k. epoxy resin systems for concrete;

l. flexible plastic gaskets and sealants for culvert pipe;

m. preformed elastomeric compression joint sealers;

n. form release agents;

o. hydrated limes and quicklimes;

p. lubricant adhesives;

q. manhole steps;

r. metallic detection tapes and wires;

s. mineral fillers for asphaltic concrete;

t. paint, activated epoxy primers and topcoats;

u. paint-inorganic zinc primers and topcoats;

v. paint-organic zinc primers and topcoats;

w. paints, high build water borne traffic;

x. plastic filter cloth;

y. polyurethane polymer joint sealers;

z. portland cements and portland pozzolan cements;

aa. preformed closed cell polyethylene joint fillers;

bb. pvc extended coal tar joint sealers;

cc. raised pavement markers;

dd. rapid setting patching materials for concrete;

ee. reflective sheetings;
