Abstract
A multi-faceted field research program utilizing seven different APP modified bitumen membranes and three types of liquid applied reflective coatings began in 1991. This long-term project is intended to evaluate: 1) The performance of the various membranes and coatings, including comparison of the weathering effects on coated & uncoated membranes; 2) Comparative performance of coating application soon after membrane installation, versus coating application after the membrane has been allowed to weather (pre-weathering); 3) Thermal performance offered by coatings; and 4) Aspects of recoating. This paper includes: 1) information on the physical & thermal performance of the membranes & coatings through 11/92; 2) recommendations regarding membrane preparation prior to coating; 3) recommendations on coating; and 4) recommendations for improvements to RCMA, ARMA guide for membrane prepartion prior to coating.
